发现了广泛的变异。通过草坪草种质资源耐逆能力的鉴定,筛选出耐盐结缕草种 质材料 5 份,耐盐多年生黑麦草 8 份,耐旱高羊茅种质材料 4 份,耐热高羊茅种 质材料 10 份和草地早熟禾 6 份。上述研究为草坪草耐逆遗传规律的研究和新品 种选育奠定了材料基础。 采用耐逆的草本植物种质材料,在天津、内蒙古和湖南示范推广,探讨其栽 培关键技术,为优异耐逆新品种在特殊环境的大面积推广应用提供理论依据。 4. 微藻 在我国内陆水体采集分离培养产油微藻 300 余株,筛选出油脂含量 30%以 上、生长快、适合于大规模培养的藻种 30 余株,其中油脂含量 40%以上的藻种 2 株;建立了以无菌通气培养为基础的产油微藻筛选评价体系;目前正在利用 18S rDNA 进行产油藻种的分子鉴定工作。 对筛选出的 2 株产油微藻优良藻种进行了大规模培养实验,建立了藻种扩 大、规模培养和浓缩采收的关键工艺,为进行产油微藻规模化生产奠定了基础。 在实验室培养条件下研究了 N、P、Fe3+、盐度、光照强度、温度对小球藻 (Chlorella sp. )生长速率、生物量和油脂产量影响的规律,发现重要理化因子对小 球藻(Chlorella sp. )生长和油脂含量的影响有两种模式:1. 适宜模式,2. 胁迫模 式。这两种模式都可以提高油脂含量,但是只有适宜模式可以提高油脂产量。上 述研究为优化产油微藻培养条件提供了理论基础。 与企业合作开展了 “红球藻产业化生产及产品质量标准研究”,制定了红球 藻产品质量标准,2010 年 10 月 29 日红球藻新资源食品获国家卫生部正式批准; 22 中国科学院植物种质创新与特色农业重点实验室 2010 年报 并在云南程海建成全球最大红球藻生产基地,实现了大规模生产。

Korban* Key Laboratory of Plant Germplasm Enhancement and Specialty Agriculture, Wuhan Botanical Garden, Chinese Academy of Sciences, Moshan, Wuhan 430074, People’s Republic of China (Y.H.); and Department of Natural Resources and Environmental Sciences (S.V., R.E.S.-G., S.R.-M., D.Z., S.S.K.) and Department of Crop Sciences (A.V.L.), University of Illinois, Urbana, Illinois 61801 Three genes encoding flavonoid 3#-hydroxylase (F3#H) in apple (Malus 3 domestica), designated MdF3#HI, MdF3#HIIa, and MdF3#HIIb, have been identified. MdF3#HIIa and MdF3#HIIb are almost identical in amino acid sequences, and they are allelic, whereas MdF3#HI has 91% nucleotide sequence identity in the coding region to both MdF3#HIIa and MdF3#HIIb. MdF3#HI and MdF3#HII genes are mapped onto linkage groups 14 and 6, respectively, of the apple genome. Throughout the development of apple fruit, transcriptional levels of MdF3#H genes along with other anthocyanin biosynthesis genes are higher in the redskinned cv Red Delicious than that in the yellow-skinned cv Golden Delicious. Moreover, patterns of MdF3#H gene expression correspond to accumulation patterns of flavonoids in apple fruit. These findings suggest that MdF3#H genes are coordinately expressed with other genes in the anthocyanin biosynthetic pathway in apple. The functionality of these apple F3#H genes has been demonstrated via their ectopic expression in both the Arabidopsis (Arabidopsis thaliana) transparent testa7-1 (tt7) mutant and tobacco (Nicotiana tabacum). When grown under nitrogen-deficient conditions, transgenic Arabidopsis tt7 seedlings expressing apple F3#H regained red color pigmentation and significantly accumulated both 4#-hydrylated pelargonidin and 3#,4#-hydrylated cyanidin. When compared with wild-type plants, flowers of transgenic tobacco lines overexpressing apple F3#H genes exhibited enhanced red color pigmentation. This suggests that the F3#H enzyme may coordinately interact with other flavonoid enzymes in the anthocyanin biosynthesis pathway. Flavonoids are ubiquitous secondary metabolites in higher plants and play important roles in myriad activities, such as protecting plants from UV radiation and pathogen infection, providing flowers and seeds with pigmentation to attract pollinators and seed dispersers, and reducing the risk of oxidative damage to human health (Regan et al., 2001; Schaefer et al., 2004; Veeriah et al., 2006). Flavonoids consist mainly of anthocyanins, chalcone, flavone, flavonol, flavanone, 1 This work was supported by the Illinois Council for Food and Agricultural Research (grant no. 06I–003–3–SEN) and the U.S. Department of Agriculture National Research Initiative Plant Genome Program (project no. 2005–35300–15538). 2 Present address: Facultad de Ciencias Quı́micas, Universidad Autónoma de San Luis Potosı́, Av.

Of these flavonoid molecules, anthocyanins are broadly distributed in flowering plants and predominantly contribute to both flower and fruit colors. The biosynthetic pathway of anthocyanins has been well established in different plants, including petunia (Petunia hybrida), snapdragon (Antirrhinum majus), and maize (Zea mays; Holton and Cornish, 1995; Winkel-Shirley, 2001; Grotewold, 2006). Briefly, the biosynthesis of anthocyanins begins with the condensation of malonyl-CoA with 4-coumaroyl-CoA, leading to the formation of naringenin chalcone (Fig. 1), and this reaction is catalyzed by the enzyme chalcone synthase (CHS). The chalcone is subsequently converted into naringenin by chalcone flavanone isomerase (CHI). Naringenin is then hydroxylated, at the 3# position of the central ring, by flavanone 3-hydroxylase (F3H) to produce dihydrokaempferol (DHK). DHK can be further hydroxylated at the 3# position or at both 3# and 5# positions of the B-ring to produce dihydroquercetin and dihydromyricetin, respectively. DHK, dihydroquercetin, and dihydromyricetin generally lead to the production of the brick-red/orange pelargonidin-, red/pink cyanidin-, and blue/violet delphinidin-based pigments, respectively (Grotewold, 2006). Therefore, the hydroxylation pattern plays an important role in coloration. Moreover, the hydroxylation pattern is also an important deter- Plant PhysiologyÒ, June 2010, Vol. 153, pp. 806–820, www.plantphysiol.org Ó 2010 American Society of Plant Biologists Proteomics 2010, 10, 1861–1874 1861 DOI 10.1002/pmic.200900694 RESEARCH ARTICLE Proteomic analysis of rice seedlings infected by Sinorhizobium meliloti 1021 Feng Chi1, Pingfang Yang2, Feng Han1, Yuxiang Jing1 and Shihua Shen1 1 The Research and Development Center for Energy Plants, Institute of Botany, Chinese Academy of Sciences, Beijing, P.

China Rhizobial endophytes infect and colonize not only leguminous plants, but several nonleguminous species as well. Using green fluorescent protein tagging technique, it has been shown that Rhizobia infect different varieties of rice species and migrate from plant roots to aerial tissues such as leaf sheaths and leaves. The interaction between them was found to promote the growth of rice. The growth promotion is the cumulative result of enhanced photosynthesis and stress resistance. In addition, indole-3-acetic acid also contributes to the promotion. Gel-based comparative proteomic approaches were applied to analyze the protein profiles of three different tissues (root, leaf sheath and leaf) of Sinorhizobium meliloti 1021 inoculated rice in order to get an understanding about the molecular mechanism. Upon the inoculation of rhizobia, proteins involved in nine different functional categories were either up-regulated or down-regulated. Photosynthesis related proteins were up-regulated only in leaf sheath and leaf, while the up-regulated proteins in root were exclusively defense related. The results implied that there might have been an increase in the import and transport of proteins involved in light and dark reactions to the chloroplast as well as more efficient distribution of nutrients, hence enhanced photosynthesis. Although the initiation of defensive reactions mainly occurred in roots, some different defense mechanisms were also evoked in the aerial tissues.

The interaction between Nod factors and Lysm-Like receptors initiates a signal transduction pathway that is critical for the invasion process [7–9].

In this study, the impact of SA pretreatment on photosynthesis was evaluated in the leaves of young grapevines before heat stress (25°C), during heat stress (43°C for 5 h), and through the following recovery period (25°C). Photosynthetic measures included gas exchange parameters, PSII electron transport, energy dissipation, and Rubisco activation state. The levels of heat shock proteins (HSPs) in the chloroplast were also investigated. Results: SA did not significantly (P < 0.05) influence the net photosynthesis rate (Pn) of leaves before heat stress. But, SA did alleviate declines in Pn and Rubisco activition state, and did not alter negative changes in PSII parameters (donor side, acceptor side and reaction center QA) under heat stress. Following heat treatment, the recovery of Pn in SA-treated leaves was accelerated compared with the control (H2O-treated) leaves, and, donor and acceptor parameters of PSII in SA-treated leaves recovered to normal levels more rapidly than in the controls. Rubisco, however, was not significantly (P < 0.05) influenced by SA. Before heat stress, SA did not affect level of HSP 21, but the HSP21 immune signal increased in both SA-treated and control leaves during heat stress. During the recovery period, HSP21 levels remained high through the end of the experiment in the SA-treated leaves, but decreased in controls. Conclusion: SA pretreatment alleviated the heat stress induced decrease in Pn mainly through maintaining higher Rubisco activition state, and it accelerated the recovery of Pn mainly through effects on PSII function. These effects of SA may be related in part to enhanced levels of HSP21. Background Heat stress due to high ambient temperatures is a serious threat to crop production [1]. Photosynthesis is one of the most sensitive physiological processes to heat stress in green plants [2]. Photochemical reactions in thylakoid lamellae in the chloroplast stroma have been suggested as the primary sites of injury at high temperature [3]. Heat stress may lead to the dissociation of the oxygen evolving complex (OEC), resulting in an imbalance during the electron flow from OEC toward the * Correspondence: shhli@wbcas.cn 4 Key Laboratory of Pant Germplasm Enhancement and Speciality Agriculture, Wuhan Botanical Garden, Chinese Academy of Sciences, Wuhan 430074, PR China acceptor side of photosystem II (PSII) [4]. Heat stress may also impair other parts of the reaction center, e.g., the D1 and/or the D2 proteins [5]. Several studies have suggested that heat stress inhibits electron transport at the acceptor side of PSII [6-8]. Direct measurements of the redox potential of QA have demonstrated that heat stress induces an increase in the midpoint redox potential of the Q A /Q A - couple in which electron transfer from QA- to the secondary quinone electron acceptor of PSII (QB ) is inhibited [6-8]. On the other hand, some studies have shown that the decreased photosynthesis could be attributed to the perturbations of biochemical processes, such as decreases in ribulose bisphosphate carboxylase/oxygenase (Rubisco) activity and decreases © 2010 Wang et al; licensee BioMed Central Ltd.

Et Zucc.) Maxim Shaohua Zeng1,2†, Gong Xiao1,2†, Juan Guo1,2, Zhangjun Fei3,4, Yanqin Xu1, Bruce A Roe5, Ying Wang1* Abstract Background: Epimedium sagittatum (Sieb. Et Zucc.) Maxim, a traditional Chinese medicinal plant species, has been used extensively as genuine medicinal materials. Certain Epimedium species are endangered due to commercial overexploition, while sustainable application studies, conservation genetics, systematics, and marker-assisted selection (MAS) of Epimedium is less-studied due to the lack of molecular markers. Here, we report a set of expressed sequence tags (ESTs) and simple sequence repeats (SSRs) identified in these ESTs for E. sagittatum. Results: cDNAs of E. sagittatum are sequenced using 454 GS-FLX pyrosequencing technology. The raw reads are cleaned and assembled into a total of 76,459 consensus sequences comprising of 17,231 contigs and 59,228 singlets. About 38.5% (29,466) of the consensus sequences significantly match to the non-redundant protein database (E-value < 1e-10), 22,295 of which are further annotated using Gene Ontology (GO) terms. A total of 2,810 EST-SSRs is identified from the Epimedium EST dataset. Trinucleotide SSR is the dominant repeat type (55.2%) followed by dinucleotide (30.4%), tetranuleotide (7.3%), hexanucleotide (4.9%), and pentanucleotide (2.2%) SSR. The dominant repeat motif is AAG/CTT (23.6%) followed by AG/CT (19.3%), ACC/GGT (11.1%), AT/AT (7.5%), and AAC/ GTT (5.9%). Thirty-two SSR-ESTs are randomly selected and primer pairs are synthesized for testing the transferability across 52 Epimedium species. Eighteen primer pairs (85.7%) could be successfully transferred to Epimedium species and sixteen of those show high genetic diversity with 0.35 of observed heterozygosity (Ho) and 0.65 of expected heterozygosity (He) and high number of alleles per locus (11.9). Conclusion: A large EST dataset with a total of 76,459 consensus sequences is generated, aiming to provide sequence information for deciphering secondary metabolism, especially for flavonoid pathway in Epimedium. A total of 2,810 EST-SSRs is identified from EST dataset and ~1580 EST-SSR markers are transferable. E. sagittatum ESTSSR transferability to the major Epimedium germplasm is up to 85.7%. Therefore, this EST dataset and EST-SSRs will be a powerful resource for further studies such as taxonomy, molecular breeding, genetics, genomics, and secondary metabolism in Epimedium species. Background Herb epimedii, a traditional Chinese medicinal herb, is prepared from the aerial parts of Epimedium species of Berberidaceae, which is a basal eudicot family containing enormous medicinal plants.

Maxim, together with other four Epimedium species, E. brevicornu Maxim, E. pubescens Maxim, E. wushanense T. S. Ying, and E. koreanum Nakai, is listed in Chinese Pharmacopoeia [1]. Herb epimediicontains various bioactive components and has been utilized extensively as a tonic and antirheumatic medicinal herb for thousands of years in China. Currently, Herb epimedii is still widely used to treat many diseases such as impotence, frequency/urgency of urination, coronary heart disease, chronic bronchitis, and neurasthenia [2].

In the present study, microsatellites and nucleotide sequences were employed to elucidate the domestication genetics of soybean. † Methods The genomes of 79 landrace soybeans (endemic cultivated soybeans) and 231 wild soybeans (G. soja) that represented the species-wide distribution of wild soybean in East Asia were scanned with 56 microsatellites to identify the genetic structure and domestication origin of soybean. To understand better the domestication bottleneck, four nucleotide sequences were selected to simulate the domestication bottleneck. † Key Results Model-based analysis revealed that most of the landrace genotypes were assigned to the inferred wild soybean cluster of south China, South Korea and Japan. Phylogeny for wild and landrace soybeans showed that all landrace soybeans formed a single cluster supporting a monophyletic origin of all the cultivars. The populations of the nearest branches which were basal to the cultivar lineage were wild soybeans from south China. The coalescent simulation detected a bottleneck severity of K′ ¼ 2 during soybean domestication, which could be explained by a foundation population of 6000 individuals if domestication duration lasted 3000 years. † Conclusions As a result of integrating geographic distribution with microsatellite genotype assignment and phylogeny between landrace and wild soybeans, a single origin of soybean in south China is proposed. The coalescent simulation revealed a moderate genetic bottleneck with an effective wild soybean population used for domestication estimated to be ≈2 % of the total number of ancestral wild soybeans. Wild soybeans in Asia, especially in south China contain tremendous genetic resources for cultivar improvement.

IN T RO DU C T IO N The origin of agriculture known as the Neolithic revolution in human history has resulted in the transition from a hunter-gather mode to an agricultural-based society (Diamond, 2002; Salamini et al., 2002). Domestication of animal and plant has played an essential role in the rising of agriculture (Diamond, 2002; Salamini et al., 2002). Making the genetics of domestication clearer could lead to a more comprehensive understanding of the evolution and history of crops and provide valuable information not only on the increasing demand of improvement of yield and quality, but also on the origin of agriculture (Jones and Brown, 2000; Diamond, 2002). Domestication was an evolutionary process in which several characters such as loss of seed dispersal, increase in grain size and synchronous ripening and so on, were adaptively evolved and selected by human beings (Brown et al., 2009; Glémin and Bataillon, 2009). Modern crops, especially landraces that descended from the wild-relative populations should maintain many of the features from wild populations. Therefore, genotypic comparison between cultivars and wild relatives from the natural distribution areas would indicate the direct ancestors of the crops (Brown et al., 2009). Recently, molecular genetics has been used to trace the evolutionary origin and domestication history of crops, such as common bean, sunflower, einkorn wheat, rice, maize and potato (Heun et al., 1997; Matsuoka et al., 2002; Harter et al., 2004; Chacón S et al., 2005; Spooner et al., 2005; Doebley et al., 2006; Londo et al., 2006; Smith, 2006). Domestication was accompanied by a reduction in genetic diversity, as well as loss of useful traits reserved in wild relatives. During domestication, lines that contained agronomically important characters were selected, which resulted in a genome-wide reduction of genetic diversity or selective sweep in domesticated crops (Tanksley and McCouch, 1997; Buckler et al., 2001; Diamond, 2002). For example, it was suggested that several grasses had about two-thirds of the genetic diversity of their wild relatives (Buckler et al., # The Author 2010.

Phylogenetic comparisons for a selection of orthologues among several related species in Ericales and two outgroups permitted placement of duplication events in relation to lineage divergences. Gene ontology (GO) categories were analysed for each whole-genome duplication (WGD) and the whole transcriptome. † Key Results Evidence for three ancient WGDs in Actinidia was found. Analyses of paleologue GO categories indicated a different pattern of retained genes for each genome duplication, but a pattern consistent with the dosage-balance hypothesis among all retained paleologues. † Conclusions This study provides evidence for one independent WGD in the ancestry of Actinidia (Ad-a), a WGD shared by Actinidia and Camellia (Ad-b), and the well-established At-g WGD that occurred prior to the divergence of all taxa examined. More ESTs in other taxa are needed to elucidate which groups in Ericales share the Ad-b or Ad-a duplications and their impact on diversification.

IN T RO DU C T IO N The importance of polyploidy, or whole genome duplication, in plant evolution has been long recognized by researchers. Nearly 35 % of flowering plants are of recent polyploid provenance and at least 15 % of angiosperm speciation events are caused by whole genome duplication (Wood et al., 2009). Using recently developed genomic approaches, several ancient genome duplication events have also been inferred during the evolution of flowering plants (Blanc and Wolfe, 2004; Cui et al., 2006; Barker et al., 2008; Soltis et al., 2009). Recent polyploids are easy to detect by changes in chromosome numbers, genome size and gene copy number compared with progenitors, but ancient polyploids, or paleopolyploids, are much harder to identify because diploidization, gene loss and chromosomal rearrangements erode the signal. Despite the obfuscating action of these forces, paleopolyploidy may still be inferred by recognition of homoeologous chromosomes or large bursts of gene duplication (Barker and Wolf, 2010). Although completely sequenced and assembled nuclear genomes provide the ultimate resource for inferring paleopolyploidy, the identification of peaks of gene duplications in expressed sequenced tags (ESTs) provides an economical method to survey ancient polyploidy. The thousands of ESTs available for many plants provide a useful ‘snapshot’ of each genome. Large-scale duplication events lead to a punctuated, dramatic increase in the number of duplicated genes (Lynch and Connery, 2000; Blanc and Wolfe, 2004). The resulting excess of paralogues of a particular age produces a peak in the age distribution of duplications across gene families within a genome. This approach has been successfully employed in a variety of plants including wheat (Blanc and Wolfe, 2004), maize (Blanc and Wolfe, 2004; Schlueter et al., 2004), Solanum (Schlueter et al., 2004; Blanc and Wolfe, 2004; Cui et al., 2006), Populus (Sterck et al., 2005), Arabidopsis (Blanc and Wolfe, 2004; Maere et al., 2005; Barker et al., 2009), lettuce (Barker et al., 2008) and sunflower (Barker et al., 2008). Researchers have begun to elucidate the phylogenetic position of paleopolyploidizations in relation to lineage divergence by combining genomic and phylogenetic methods in the Fabaceae (Pfeil et al., 2005), Compositae (Barker et al., 2008) and Brassicales (Bowers et al., 2003; Schranz and Mitchell-Olds, 2006; Tang et al., 2008; Barker et al., 2009). The genus Actinidia, well known as kiwifruit, contains 76 species of climbing plants originating mainly in China (Huang and Ferguson, 2007). Over the past three decades, kiwifruit has developed into an important horticultural cash crop and a fruit industry worldwide (Huang and Ferguson, # The Author 2010.

Jatropha curcas Population genetics analysis showed that average Nei’s gene diversity (He) was 0.19, and Oil content average Shannon Information Index (I ) was 0.292, indicating a relatively high genetic Genetic diversity variation in the collections. The dendrogram based on Nei’s genetic distance showed that Genetic distance distinct genetic differentiation occurred in Chinese Jatropha, most of the mainland Cluster analysis accessions were clustered into a sub-group (Ia), and accessions from Hainan Island and its Core collection of germplasm neighboring Guangdong province were generally clustered into another sub-group (Ib). A core germplasm collection was established by SCR strategy. This core collection consisted of 46 accessions that accounted 20.54% of the initial collection, and maintained over 90% of observed alleles, polymorphic loci and polymorphism rate. Slight correlation of oil content variation and genetic diversity was observed. Tropical populations are the most important genetic resources and crosses between this tropics and the mainland are recommended for genetic improvement of Jatropha in China. ª 2010 Elsevier Ltd.

Introduction Biofuel is renewable and benign to environment, and has showed a great potential in coping with worldwide energy crisis and increasingly serious environmental problems. It has attracted attention from most of the countries in the world as an alternative to fossil fuels. According to the USDA report in 2007, China is the third largest biofuel producer in the world just behind Brazil and America [1,2], and development of biofuel has great prospect in China because of the good basis and great energy demand in the future. It is essential for biofuel production to develop feedstocks. It is also not easy to find a proper feedstock in the first phase of development.

All explants could be de-differentiated. However, subsequent callus growth depended mainly on genotype and tissue type. Nonembryogenic callus accumulated more resveratrols and piceids and had a higher growth index than pro-embryogenic and embryogenic calli. UV-C irradiation for 20 min was most efficient in promoting both the accumulation of resveratrols and piceids and callus growth index. There was dynamic production of resveratrols and piceids in UV-C-irradiated leaf-derived calli over a 72 h period, with optimum harvest time for the highest total stilbene content at 48 h. Accumulation of stilbenes in UV-C-irradiated calli depended upon genetic background and tissue type, with higher stilbene contents in two interspecific root stocks and leaf or exocarp explants.

Introduction Stilbenes are nonflavonoid phenolics found in the tissues and organs of plants in several families, including Vitaceae, Arachaceae and Pinaceae (Gambino, Bondaz, & Gribaudo, 2006). They are thought to play a phytoalexin-role in plants that produce them. One of the most relevant and extensively studied stilbenes is trans-resveratrol (trans-3,5,40 -trihydroxystilbene) (Cantos, TomásBarberán, Martínez, & Espín, 2003), which has been reported to have a number of health-beneficial properties, such as antioxidant capacity, cardiovascular protective effect, antimutagenic properties and estrogenic and cancer chemopreventive activity (Hung, Chen, Huang, Lee, & Su, 2000; Sgambato et al., 2001). Trans-resveratrol is an important and leading stilbenic compound in many plants, but its cis-form has not been detected often. In addition to resveratrol, its glucoside (piceid) has also shown beneficial effects on health. For example, trans-piceid can inhibit low-density lipoprotein oxidation, reduce platelet aggregation, and act as a tumour and metastatic carcinoma inhibitor (Kimura & Okuda, 2000). There has been particular interest in grapes, as they encompass a broad germplasm base, are widely planted and consumed and * Corresponding author at: Institute of Botany, Chinese Academy of Sciences, Wuhan 430074, PR China.

However, stilbene biosynthesis and accumulation in grape tissues under natural conditions varies with environment and growth stage of the plant. Plant cell culture potentially offers uniform secondary-product synthesis by eliminating effects of unforeseen climatic conditions and diseases, as occurs in field-grown plants (Trejo-Tapia et al., 2008). Thus, callus and cell suspension cultures are attractive for optimising production of secondary metabolites. However, low and unstable yields have been major obstacles to developing large-scale production systems using plant cells. Many studies of Vitis cell-cultures have been undertaken to stabilise and increase stilbene yield, but most attempts have been limited to Vitis vinifera cultivars and grape leaf tissues. Studies at the Vitis germplasm level have shown that resveratrol content depends on genotype (Li, Wu, Wang, & Li, 2006), with range 0.01–356 lg g1 fresh weight (Fw) in berry skins and 0.01–35.1 lg g1 Fw in seeds. All V. vinifera cultivars have low trans-resveratrol concentrations, but some species–hybrid rootstocks have much higher transresveratrol concentrations in their berry skins than has V. vinifera. Moreover, grape leaves accumulate stilbenes at low levels under natural conditions, and there are different concentrations of trans-resveratrol in different tissue types within the same genotype (Li et al., 2006; Tassoni et al., 2005; Zamboni, Vrhovsek, Kassemeyer, Mattivi, & Velasco, 2006).

Email: tingwang@wbgcas.cn B Abstract. Island populations provide an ideal natural experiment with which to study the forces driving population evolution. Seventeen populations of Dacrydium pectinatum de Laubenfels on Hainan Island, China, were sampled throughout its distribution range and then assessed using inter-simple sequence repeats (ISSR) markers. Population genetic parameters were estimated by Bayesian approaches as well as conventional methods. Genetic bottleneck signatures were further dissected by performing three heterozygosity excess tests and the mode-shift indicator test. Compared with other coniferous species, a relatively high level of genetic variation and a low degree of differentiation was revealed in D. pectinatum. In addition, severe bottlenecks were identified at local, regional as well as range-wide scale. Ecological and life-history traits were suggested to play major roles in the shaping of the genetic variation pattern. In particular, long life span could have exerted a lagging effect on both the genetic variation and differentiation of extant populations. Our findings may contribute to improving management practices for the restoration of D. pectinatum. Introduction Island systems have long been recognised as ideal natural experiments for the study of basic questions about population genetics (Darwin 1859; Grant 1998; Stuessy and Ono 1998; Bottin et al. 2005). They possess several features that are highly valuable for understanding evolutionary processes, including discrete entities, small areas but varied habitats and being often geologically dynamic (Emerson 2002). Compared with mainlands, islands’ geographic isolation and simpler environmental systems make them particularly suitable to discern the effects of mechanisms, such as genetic drift, gene flow or migration and natural selection, on the population evolution, because of the relative ease in designing experiments and analyses that are not confounded by environmental factors (Hedrick 2000; Maki 2001; White and Searle 2007). Island populations generally tend to possess low levels of genetic variation (Frankham 1997). There are several possible reasons for this genetic depauperation, including (i) the net loss of genetic variation that is associated with colonisation events and founder effects, (ii) the subsequent loss caused by the finite population size since foundation and (iii) adaptation to island environments, which can be established through the selection for favourable alleles or gene combinations (Jaenike 1973; Frankham 1997). In most cases, studies of plant species support this generalisation (Frankham 1997; Crawford et al. 2001; Maki 2001; Muller et al. 2009). However, notable exceptions do exist (Weller et al. 1996; Francisco-Ortega et al. 2000; Helenurm 2001; Hiramatsu et al. 2001; López-Pujol et al.  CSIRO 2010 2003). For example, moderate to high levels of genetic variation has been detected in a critically endangered perennial larkspur, Delphinium pentagynum subsp. formenteranum, endemic to the island of Formentera, Spain (López-Pujol et al. 2003). The plant can remain dormant for many years and allow genetically distinct individuals to be present at different years for crossing, which leads to the increase of the overall effective population size (Ne), generating a positive effect on genetic diversity (López-Pujol et al. 2003). In addition, the spatial distribution pattern of island populations should also influence the partition of genetic variation among the populations (Nielsen 2004). However, relatively few studies have systematically attempted to deal with this issue, especially for coniferous species. Hainan Island (18090 –20100 N, 108230 –111030 E) is one of the hotspots of biodiversity in China (Li 1995). Its flora contains 3164 vascular plants, 12.8% of which are endemic (Liang and Yang 2009). The island, consisting of 33 900 km2, is separated from the Chinese mainland by the Qiongzhou Strait, which is ~20 km wide and 100 m deep (Tang et al. 2003). Yan (2006) indicated that throughout the geological history, Hainan Island has experienced a connection (before the late Neogene), disconnection (from the late Neogene to the Pleistocene), reconnection (from the late Pleistocene to the early Holocene) and redisconnection (since the Holocene) with Chinese mainland. Nonetheless, it is almost certain that the process of connection and disconnection has been repeated many times through the Pleistocene, as global sea levels repeatedly rose and fell (Hope 2005).

Separation of flower color in the progeny was also observed, progeny with red flowers lighter than ‘Chaohong’, white flowers as in ‘Jinkui’ and intermediate types with a red base to the petals and white margins were all present. Flow cytometry analysis confirmed that most of the progeny were tetraploids, and molecular marker data showed that most of these tetraploid progeny had three alleles from the hexaploid parent and one allele from the diploid parent.

The planted area of worldwide kiwifruit industry has reached approximately 140,000 hectares and the total production exceeded 1.8 million metric tons (Belrose Inc. 2008). However, the international kiwifruit industry mainly relies on a few naturally selected cultivars from two infraspecific taxa of Actinidia chinensis (A. chinensis var. chinensis and A. chinensis var. deliciosa), the commercially most valuable species of the genus Actinidia, which encompasses more than 50 species and 70 taxa (Li et al. 2007).

Ex situ conserved populations of S. xylocarpa maintain intermediate levels of genetic diversity (HE ¼ 0.570– 0.640). However, a general and significant heterozygote excess was found, with a mean FIS of 0.103. S. xylocarpa was determined to be predominantly outcrossing (tm ¼ 0.992; ts ¼ 1.092). Population size and genetic diversity were found to be positively correlated (r ¼ 0.991; P ¼ 0.084).

Introduction Human activities and global climate change have led to progressive and large-scale habitat degradation, fragmentation, and loss, with consequent loss of species and genetic diversity (Heywood and Iriondo, 2003). About two-thirds of vascular plants may disappear by the end of the 21st century if aggressive conservation measures are not taken (Pitman and Jorgensen, 2002). Ex situ preservation of living plants has played a significant role as a complement to in situ conservation, especially for critically endangered species or those that are now extinct in the wild (Frankham et al., 2002). The most important ex situ conservation sites are the world’s 1800 botanical gardens, which are estimated to have preserved nearly 30% of rare or endangered plant species (Maunder, 1994; BGCI, 2003). Though great effort has been made toward plant ex situ conservation in recent years, there has been little focus in assessing the efficacy of ex situ conservation strategies. Genetic diversity is of critical importance for the maintenance of a species’ ecological and evolutionary potential to cope with a changing environment, and loss of genetic diversity within species is often associated with reduced fitness (Booy et al., 2000). Hence, measuring and maintaining genetic variation in ex situ plants are major objectives for most species conservation plans (Avise and Hamrick, 1996; Li et al., 2002; Frankham et al., 2002). Furthermore, the mating system of a population determines how genetic information is transferred from one generation to the next and how genetic diversity is distributed among individuals and populations within a species. Thus, knowledge of a plant’s mating system is useful in conservation management. However, assessing the levels of genetic variation and mating system for endangered ex situ plant species has rarely been conducted (Li et al., 2002). * Corresponding author.

Introduction Plant species with island-mainland distributions have often been considered a model for the study of isolation and genetic divergence (Chiang et al., 2006). Compared to their mainland counterparts, island populations are generally characterized as having lower genetic variation, less among-population differentiation, more significant inbreeding, and a much higher risk of extinction (Frankham, 1997, 1998; Maki, 1999; Lee et al., 2002; Nielsen, 2004). They also tend to display strong differentiation from mainland populations (Rivera-Ocasio et al., 2002; Yeh and Hu, 2005). Nevertheless, these generalizations have mainly been derived from examinations of plants with larger mainland populations but smaller island ones. For cases where mainland populations are smaller than island populations, very few studies have been conducted. Moreover, even if in plants whose mainland populations are larger, other different patterns have also been recorded such as that both island and mainland populations contain similar amount of genetic diversity (Maki and Morita, 1998), that populations within the island exhibit higher levels of genetic differentiation than those in the mainland (Maki and Morita, 1998) as well as that insular populations are not significantly differentiated from their mainland sources (Muller et al., 2009). * Corresponding author.

Effects of deficit irrigation applied to home lawns, used as means of water conservation, are an important issue. However, the impact of deficit irrigation on sucrose metabolism in tall fescue (Festuca arundinacea) is unknown and important because sucrose is the dominant form of carbohydrate transported to developing plant organs. The objectives of this study were to investigate the effects of deficit irrigation on leaf water content, osmotic potential (cS), sucrose level, and the activity of sucrose phosphate synthase [SPS; electrical conductivity (EC) 2.4.1.14], sucrose synthase (SS; EC 2.4.1.13), and acid invertase (AI; EC 3.2.1.26) in tall fescue leaves. Sods of ‘Falcon II’ tall fescue were established in polyvinylchloride (PVC) tubes (10 cm diameter · 40 cm long) filled with a mixture of sand and fritted clay [9:1 (v:v)] and then placed in growth chambers. Reference evapotranspiration rate [ETo (millimeters of water per day)] was determined by weighing the PVC tubes containing well-watered turfgrass every 3 days to determine water loss on a daily basis as ETo. Deficit irrigation treatments were applied as follows: well-watered control, mild drought stress (60% ETo), and severe drought stress (20% ETo). Leaf water content was lower at 6, 12, and 20 days of treatment for the 20% ETo treatment and 20 days after treatment began for the 60% ETo treatment. Compared with the well-watered control, cS was lower in the 60% ETo treatment on all three measurement dates. Sucrose was higher at 8 and 14 days after treatment began in the 60% ETo treatment and on all three measurement dates in the 20% ETo treatment relative to the well-watered control. No difference in sucrose level was observed between the 20% ETo and 60% ETo irrigation regimes at 8 and 14 days of treatment. Beginning 14 days after treatment, tall fescue had a higher level of SPS in the 60% ETo and 20% ETo treatments compared with the well-watered treatment. Tall fescue receiving 60% or 20% ETo had a lower level of AI activity on all measurement dates. Results suggest that the decrease in cS was accompanied by higher sucrose levels, which were the result of the increased level of SPS and SS activity and a decline in AI activity. Proper irrigation management is critical to growing quality turfgrass with limited water in arid and semiarid regions. Deficit irrigation, defined as applying water in amounts less than the reference evapotranspiration rate, is an irrigation management practice that could result in water savings (Fu et al., 2007). The ETo, measured as amount of daily water loss from a canopy under non-water-limiting conditions, often is used to estimate water requirements in turfgrass irrigation. Reduction in irrigation application not only can reduce costs associated with water consumption and can improve environmental stress tolerance, but it also prevents turfgrass from the injury of mechanical AU1 stresses, cyanobacteria, and diseases (Beard, 1973; Dernoeden, 2002; Turgeon, 2008). Some researchers have found that turfgrass is able to tolerate moderate drought (DaCosta and Huang, 2006; Fu et al., 2004; Gilbeault et al., 1985). Tall fescue, bermudagrass (Cynodon dactylon), and zoysiagrass (Zoysia japonica) irrigated to 60% or 80% of ETo exhibited similar turfgrass quality when compared with well-watered turfgrass (Fu et al., 2004). Gilbeault et al. (1985) also observed that tall fescue, kentucky bluegrass (Poa pratensis), and perennial ryegrass (Lolium perenne) had only a slightly lower level of quality when irrigated at 80% ETo relative to 100% ETo. Availability of total nonstructural carbohydrate (TNC) has been widely used as a physiological measure of stress tolerance, because carbohydrates provide energy and solutes for osmotic adjustment. Sucrose, an important component of TNC, is the dominant form of carbohydrate transported to developing plant organs and is one of the sugars stored in higher plants (Khayat and Zieslin, 1987). Sucrose also serves as an osmotic solute (Premachandra et al., 1992; Rekika et al., 1998; Tan et al., 1992; Zhang and Archbold, 1993). The effect of water deficits on sucrose levels has been reported in some plants. For example, improved responses of bean (Phaseolus vulgaris) to water deficits were associated with sucrose metabolism (Castrillo, 1992; Vassey et al., 1991). McManus et al. (2000) found that after white clover (Trifolium repens) was exposed to a period of moderate drought stress, leaf sucrose content increased significantly. Leaf sucrose level increased by 300% at the end of an Proof Only Received for publication 16 June 2010. Accepted for publication 24 Sept. 2010. 1 Corresponding author.

Based on this unprecedented abundance of data, extensive genomic changes have been revealed in the plastid genomes. Inversion is the most common mechanism that leads to gene order changes. Several inversion events have been recognized as informative phylogenetic markers, such as a 30-kb inversion found in all living vascular plants minus lycopsids and two short inversions putatively shared by all ferns. Gene loss is a common event throughout plastid genome evolution. Many genes were independently lost or transferred to the nuclear genome in multiple plant lineages. The trnR-CCG gene was lost in some clades of lycophytes, ferns, and seed plants, and all the ndh genes were absent in parasitic plants, gnetophytes, Pinaceae, and the Taiwan moth orchid. Certain parasitic plants have, in particular, lost plastid genes related to photosynthesis because of the relaxation of functional constraint. The dramatic growth of plastid genome sequences has also promoted the use of whole plastid sequences and genomic features to solve phylogenetic problems. Chloroplast phylogenomics has provided additional evidence for deep-level phylogenetic relationships as well as increased phylogenetic resolutions at low taxonomic levels. However, chloroplast phylogenomics is still in its infant stage and rigorous analysis methodology has yet to be developed. Key words chloroplast phylogenomics, comparative genomics, gene loss, genome rearrangement, plastid genome sequencing. Plastid genome (plastome) sequence information is of central importance to tracing the evolutionary history of plastids and their hosts. The small genome size and high copy number per cell have made the plastid genomes much more amenable for sequencing than nuclear genomes. Currently, there are at least 190 completely sequenced plastid genomes available, of them 163 are from various green plants, with land plants having the best representation (137) (Fig. 1). Comparative studies indicate that plastid genomes have experienced substantial rearrangements and frequent gene losses throughout plant evolution. Some genes or groups of functionally related genes have been independently lost multiple times. These plastid genomic characters have been recognized as phylogentically informative markers. Based on the complete plastid genome sequence data, chloroplast phylogenomics has emerged as an effective approach to clarifying phylogenetic relationships in plants and algae. ∗ Received: 25 September 2009 Accepted: 14 January 2010 Author for correspondence.

C 2010 Institute of Botany, Chinese Academy of Sciences 1 Overview of plastid genome sequencing A search of public databases and published work revealed 190 completely sequenced plastid genomes, with a steep increase over the last 4 years (Fig. 2). A total of 24 and 33 genome sequences were reported during 1986–2001 and 2002–2005, respectively, whereas at least 133 were released within 2006–2009. In these efforts of plastid genome sequencing, a total of 163 land plants and green algae have already been determined (Fig. 1). Under the phylogenetic framework, the distribution of plastid genomic efforts is clearly uneven (Fig. 1). Given their apparent importance, flowering plants, particularly crops, are the focus of sequencing (Pryer et al., 2002). The lack of plastid genomic data of representatives from other crucial evolutionary nodes, however, may hinder our comparative understanding of plastid genomic organization, function, and evolution. Fortunately, this situation has started to change. Since 2007, 34 plastid genomes have been sequenced for non-flowering plants including chlorophytes (12), charophytes (1), bryophytes (2), lycophytes (2), monilophytes (2), and gymnosperms (15). The plastid genomic data, which now have a more expanded taxonomic coverage, offer an excellent opportunity for the study of plastid genome evolution. Ann. Bot.

Castanopsis malipoensis and C. jinpingensis, two new species of Fagaceae from Yunnan, China, are described and illustrated. The former grows in mixed forests on limestone hills of the Malipo County and is closely related morphologically to C. xichouensis, differing from it by having thinner leaves, shorter petioles, flat glabrous cupule spines, and larger nuts. The latter is restricted to the thick forest on Mt. Wutai in the Jinping County, most resembling C. platyacantha, but differing from it by its entire leaf-margin, slender cupule spines without pubescences, and having smaller nuts. A key to the two species and their allies is provided. Key words: biodiversity, morphology, new species, taxonomy, vascular plants The genus Castanopsis (Fagaceae) is one of the dominant components of Asian tropical and subtropical broad-leaved evergreen forests, rainforests and aseasonal montane forests. Approximately 120 species of the genus have been described, of which 58, including 30 endemics, occur in China (Huang et al. 1999). Following a review of the literature (Camus 1929, Govaerts & Frodin 1998, Huang et al. 1999) and examination of herbarium collections from various institutions (A, BM, E, K, L, P, TI, HIB, HK, IBK, IBSC, KUN, PE) for the revision of the Chinese Castanopsis, we have identified two species of this genus new to science. In more recent field work, we collected several additional specimens in the Counties of Jinping and Malipo, situated at the Indo-Burma hotspot (Myers et al. 2000) in the Yunnan Province.
