چکیده
Michelia crassipes Y. W. Law (Magnoliaceae) is endemic to China and the only species with purple flowers in genus Michelia. It commonly used as an important parent for flower color improvement hybrid breeding. M. recognized endangered plant. An urgent need exists explore genetic diversity of efficiently select parents develop efficient conservation strategies. In this study, a total 128 samples were selected from seven natural populations their structure. A 14 microsatellite (SSR) markers high polymorphism repeatability developed, 218 alleles detected. This study mainly revealed three results: (1) The parameters expected heterozygosity (He = 0.536) mean Shannon’s information index (I 1.121) moderately levels population; (2) differentiation coefficient (Fst 0.108) showed that there was low level differentiation, AMOVA indicated variation existed within frequent gene exchange between populations; (3) population structure analysis originated two ancestral groups, Mantel test geographical distances significantly correlated. Our first population, which provides reference collection, utilization germplasm resources.

Genetic Diversity and Population Structure of Iranian tulips revealed by EST-SSR and NBS-LRR Markers
The genus Tulipa L. (Liliaceae) comprises about 100 species and Iran is considered as one of the main origins of tulips. In this research, genetic diversity and population structure of 27 wild populations of tulips collected from Iran were studied by 15 highly polymorphic and reproducible expressed sequenced tag-simple sequence repeat (EST-SSR) markers and 8 nucleotide binding site (NBS)-enzyme...
متن کاملAnalysis of the Genetic Diversity in Citrus (Citrus spp.) Species Using SSR Markers
Abstract Determination of genetic diversity level is important in clarifying genetic relationships, characterizing germplasm and the registration of new cultivars. In this study, genetic variation among 56 accessions (G1~G56) of Citrus including several undefined local or native genotypes and some known varieties in Jiroft, Kerman province, Iran was investigated using SSR markers. In total, 12 ...

To ascertain genetic diversity, population structure and linkage disequilibrium (LD) among a representative collection of Chinese winter wheat cultivars and lines, 90 winter wheat accessions were analyzed with 269 SSR markers distributed throughout the wheat genome. A total of 1,358 alleles were detected, with 2 to 10 alleles per locus and a mean genetic richness of 5.05. The average genetic di...

Assessment of Genetic Diversity and Population Genetic Structure of Corylus mandshurica in China Using SSR Markers
Corylus mandshurica, also known as pilose hazelnut, is an economically and ecologically important species in China. In this study, ten polymorphic simple sequence repeat (SSR) markers were applied to evaluate the genetic diversity and population structure of 348 C. mandshurica individuals among 12 populations in China. The SSR markers expressed a relatively high level of genetic diversity (Na =...
