| 摘 要： | 灰胸竹鸡Bambusicola thoracica是我国特有鸟类.本文采用聚合链式反应和直接测序的方法测定井冈山地区灰胸竹鸡3个种群线粒体DNA(mtDNA)控制区1142 bp的序列,分析其序列变异和种群遗传多样性.30个样本共发现16个变异位点和10种单倍型,其中hapl广泛分布,占所分析样本的23.33%,是其祖先单倍型.3个种群的平均单倍型多样性和核苷酸多样性分别为0.815和0.00243.青原区种群与其它两个种群遗传分化显著,基因交流受限制.受隔离影响,青原区种群遗传多样性最低.在系统发生树上,10种单倍型形成两支,井冈山种群和永新县种群聚在一起,与其地理位置相一致.

| Abstract: | Bambusicola thoracica is an endemic species in China.Polymerase chain reaction and dideoxy direct sequencing methods were used to analyze the genetic diversity of bamboo partridge.A total of 1142 nucleotides of the mitochondrial DNA control region of three populations collected from Jinggangshan region(Qingyuanqu,Jinggangshan and Yongxinxian districts)were sequenced.The sixteen variable sites defined ten haplotypes from 30 samples.The most common haplotype hap1 was an ancestral haplotype,which had a cumulat... |
