| 摘 要： | 为研究安徽长江水系黄鳝(Monopterus albus)的遗传多样性和群体遗传结构,测定了其6个地理群体(当涂、无为、繁昌、贵池、怀宁和望江)共178尾个体的线粒体DNA控制区部分序列.对其长度为556～558 bp的控制区同源序列进行分析,共检测到变异位点41个(变异率7.35％),单倍型56种.平均单倍型多样性和核苷酸多样性分别为0.694～0.954、0.00237～0.01382.群体分化指数(Fst)和基因流(Nm)分别为0.01974～0.87529、0.07124～24.82928,分子变异分析(AMOVA)中,群体间遗传变异占61.72％,表明黄鳝群体间具有明显的遗传分化.基于单倍型或群体间遗传距离的分子系统进化树均显示,6个地理群体分为两支:当涂与繁昌群体聚为一支,其余4群体聚为另一支.

| Abstract: | To assess the genetic diversity and population structure of Monopterus albus, 178 individuals of 6
populations (DT, WW, FC, GC, HN, WJ) from Anhui reaches in the Yangtze River were investigated based on 556-558 bp
nucleotide sequences of mtDNA partial control region. The sequences analysis results showed that 41 variable sites
(mutation rates of 7.35%), 56 haplotypes were detected. The haplotype diversity (Hd) and nucleotide diversity (Pi) were
0.694-0.954 and 0.00237-0.01382, respectively. Analysis of molecular variance (AMOVA) revealed that genetic variation
among the populations was 61.72%. These results indicated that there were significant genetic differentiations among
populations. NJ-tree based on haplotypes or genetic distances among populations showed that DT and FC populations were
clustered as one, and other 4 population was as another independent cluster. |
