Microsatellite analysis of genetic diversity and phylogenetic relationship of four different geographical populations of Si-nonovacula constricta
摘要
Abstract
Twelve microsatellite markers were used to study genetic diversity and phylogenetic relationship of four geographic populations of razor clam Sinonovacula constricta. The four populations were sampled from Yunxiao City of Fujian, Zhanjiang City of Guangdong, Tanggu City of Tianjin and Yueqing City of Zhejiang. The results showed that total of 46 alleles were found among 12 SSR markers. The average observed number of alleles (Ao) was from 3.25 to 3.50, the average observed heterozygosity (Ho) was from 0.59 to 0.74, the average excepted het-erozygosity (He) was from 0.55 to 0.58 and the average polymorphism information content (PIC) ranged from 0.46 to 0.50, respectively. All of these results indicated that genetic diversity of the four populations was at a medium level. UPGMA cluster analysis showed that Yueqing population was clustered with Tanggu population into one clad, then Yunxiao population and Zhanjiang population were in a second group. The value of the F-statistics was 0.07 and this suggested that the four populations of S.Constricta had a relatively lower genetic variation and its genetic structure between populations was weak.关键词
