Preliminary Analysis on the Genetic Diversity in Four Populations of Leiocassis longirostris by Using Microsatellite Markers
摘要
Abstract
The research aimed to understand genetic diversity and genetic structure of Leiocassis longirostris and to provide effectively genetic background after the finishing of three gorges dam.Genetic diversity and genetic variation in four populations of Leiocassis longirostris distributed in the upper and mid-lower Yangtze River were analyzed by eight microsatellite markers. The results indicated that mean number of alleles in four populations (Chongqing, Shishou, Wuhan,Jiujiang)was 7.3,5.6,4.8 and 3.3 respectively. Mean observed heterozygosity (Ho) was 0.732, 0.312,0.681 and 0.877 respectively. There was poorly genetic diversity in the four populations of Leiocassis longirostris distributed in Yangtze River system. The genetic distance among Shishou,Wuhan and Jiujiang was more closely than that between them and Chongqing. The genetic diversity is low in four populations of Leiocassis longirostris from Yangtze River.关键词
