Transferability analysis of EST-SSR markers of Castanea mollissima to Castanopsis fargesii
摘要
Abstract
Simple sequence repeats(SSR),also known as microsatellite molecular markers,have been cross-amplified successfully in closely related species of the same genus and even across genera within the same family. In the present study, 124 primer pairs of polymorphic EST-SSR originally developed from Castanea mollissima were cross-amplified in Castanopsis fargesii. Results indicated that 42. 7% of Castanea mollssima EST-SSR primers were successfully cross-amplified in Castanopsis far gesii and 56. 6% were polymorphic. The genetic diversity of 4 populations of C. fargesii were investigated with polymorphic EST-SSRs, preliminary results showed that C. fargesii possessed high levels of genetic diversity(Na=6.105,Ho=0. 563,He-0.621). These polymorphic EST-SSR primers would provide a powerful tool for further investigation on population genetics of C. fargesii.关键词
