Identification and Analysis of Genetic Diversity Structure Within Pisum Genus Based on Microsatellite Markers

To assesse the genetic diversity among wild and cultivated accessions of 8 taxonomic groups in 2 species, and 5 subspecies under Pisum genus, and to analyze population structure and their genetic relationships among various groups of taxonomy, the study tried to verify the fitness of traditionally botanical taxonomic system under Pisum genus and to provide essential information for the exploration and utilization of wild relatives of pea genetic resources. 197 Pisum accessions from 62 counties of 5 continents were employed for SSR analysis using 21 polymorphic primer pairs in this study. Except for cultivated field pea Pisum sativum ssp. sativum var. sativum （94 genotypes）, also included were wild relative genotypes that were classified as belonging to P. fulvum, P. sativum ssp.abyssinicum, P. sativum ssp. asiaticum, P. sativum ssp. transcaucasicum, P. sativum ssp. elatius var. elatius, P. sativum ssp. elatius var. pumilio and P. sativum ssp. sativum var. arvense （103 genotypes）. The PCA analyses and 3-dimension PCA graphs were conducted and drawn by NTSYSpc 2.2d statistical package. Nei78 genetic distances among groups of genetic resources were calculated, and cluster analysis using UPGMA method was carried out by using Popgene V1.32 statistical package, the dendrogram was drawn by MEGA3.1 statistical package. Allelic statistics were carried out by Popgene V1.32. The significance test between groups of genotypes was carried out by Fstat V2.9.3.2 statistical package. 104 polymorphic bands were amplified using 21 SSR primer pairs with unambiguous unique polymorphic bands. 4.95 alleles were detected by each SSR primer pair in average, of which 65.56% were effective alleles for diversity. PSAD270, PSAC58, PSAA18, PSAC75, PSAA175 and PSAB72 were the most effective SSR pairs. SSR alleles were uniformly distributed among botanical taxon units under Pisum genus, but significant difference appeared in most pairwise comparisons for genetic diversity between taxon unit based groups of genetic resources. Genetic diversity level of wild species P. fulvum was much lower than the cultivated species P. sativum. Under species P. sativum, P. sativum ssp. sativum var. sativum and P. sativum ssp. asiaticum were the highest in gentic diversity, followed by P. sativum ssp. elatius var. elatius and P. sativum ssp. transcaucasicum, P. sativum ssp. elatius var. pumilio, P. sativum ssp. sativum vat. arvense and P. sativum ssp. abyssinicum were the lowest. Four gene pool clusters were detected under Pisum genus by using PCA analysis. Gene pool ＂fulvum＂ mainly consisted of wild species Pisum fulvum, gene pool ＂abyssinicum＂ mainly consisted of P. sativum ssp. abyssinicum, and gene pool ＂arvense＂ mainly consisted of P. sativum ssp. sativum var. arvense. While gene pool ＂sativum＂ were composed by 5 botanical taxon units, they are P. sativum ssp. asiaticum, P. sativum ssp. elatius var. elatius, P. sativum ssp. transcaucasicum, P. sativum ssp. elatius var. pumilio and P. sativum ssp. sativum var. sativum. ＂sativum＂ gene pool constructed the primary gene pool of cultivated genetic resources; ＂fulvum＂ gene pool, ＂abyssinicum＂ gene pool and ＂arvense＂ gene pool together constructed the secondary gene pool of cultivated genetic resources. Pairwise Nei78 genetic distance among botanical taxon based groups of pea genetic resources ranged from 7.531 to 35.956, 3 large cluster groups were identified based on the UPGMA dendrogram. Group Ⅰ equals to ＂sativum＂ and ＂arvense＂ gene pools, Group Ⅱ equals to ＂abyssinicum＂ gene pool, and Group Ⅲ equals to ＂fulvum＂ gene pool. The UPGMA clustering results generally supporting the PCA clusting results. There were significant differences among most botanical groups under Pisum genus, with clear separation of four gene pools for genetic diversity structure. The research results partially support the traditional botanical taxonomy under Pisum genus, and pointed out its advantage and shortcoming. In order to broaden the genetic bases of pea varieties, the genetic potentials in the four gene pools should be thoroughly exploited.

松潘生态修复模式区生物多样性与稳定性研究

九寨-黄龙世界自然遗产地位于我国西部典型的山地生态脆弱区,自2001年以来松潘县在退耕还林工程进行了不同树种配制模式的实践,共计营造了12个生态经济林模式.它们分别为:1.枸杞,2.沙棘,3.山桃+云杉,4.山杏+云杉,5.云杉,6.西蜀丁香+陇东海棠,7.云杉+阿根廷柳,8.云杉+青杨,9.阿根廷柳,10.阿根廷柳+青杨,11.青杨,12.山杏+阿根廷柳模式.通过对这12个模式群落与各层次物种多样性的分析比较,发现绝大多数模式木本层多样性并不高,而草本层则物种数多为20种左右,香农威纳指数都达到2.0以上,因而,群落总体多样性很可观.运用Godron M稳定性测定方法检验其生态稳定性表明:各模式的生态稳定性与理论上20/80的稳定点尚有相当距离;其大小依次为:1.枸杞,2.沙棘,4.山杏+云杉,6.西蜀丁香+陇东海棠,10.阿根廷柳+青杨,12.山杏+阿根廷柳,5.云杉,8.云杉+青杨,7.云杉+阿根廷柳,11.青杨,9.阿根廷柳,3.山桃+云杉,这表明模式构建后仍处在较脆弱的状态.稳定性与其多样性之间的拟合也表明稳定性与多样性并无多少明显相关,甚至还有呈现负相关的趋势.这预示着多样性与稳定性之间不存在简单的线性关系,而是可能存在一个多样性阈值.

Abstract：

The World Natural Heritage-Jiuzaigou & Huanglong-is located in the eco-vulnerablele areas of West China. Since 2001, a total of 12 reconstruction models of the degraded landscape in the eco-vulnerable areas have been implemented in Songpan County, i. e. 1) Lycium chinense; 2) Hippophae rhamnoides;3) Amygdalus davidiana + Picea asperata ; 4) Armeniaca sibirica + P. asperata; 5) P. asperata; 6)Syringa komarowii +Maluskansuensis; 7) P. asperata + Salix argentinensis; 8) P. asperata+ Populus cathayana; 9) S. argentinensis; 10) S. argentinensis + P. cathayana; 11) P. cathayanaand 12) A.sibirica+ S. argentinensis. An analysis of both horizontal and vertical species diversity in these 12 models showed that there were generally poor species richness and diversity in the woody layer. In contrast, the herb layer of most models possessed considerable diversity, with about 20 species and a Shannon-Weiner index of over 2.0. In addition, most models possessed sound species diversity, contributed by diversity in the herb layers. Estimation of bio-stability with M. Godron stability method demonstrated that the ecostability of each model fell quite apart from the theoretic stable point (20/80), being in the sequence of L.chinense > H. rhamnoides > A. sibirica+ P. asperata > S. komarowii + M. kansuensis> S. argentinensis + P. cathayana> A. sibirica + S. argentinensis > P. asperata > P. asperata + Populus cathayana > P. asperata + S. argentinensis > P. cathayana > S. argentinensis > Amygdalus davidiana + P. asperata, indicating that these models remained in their fragile status. Simulation between their species diversity and ecological stability also indicated that little, if any, simple linear correlation existed between them and, sometimes, even a negative correlation was shown, suggesting that there may be a threshold of biodiversity other than a simple linear relationship between diversity and stability.
