摘要
对我国五大淡水湖日本沼虾100个野生个体的线粒体细胞色素氧化酶亚基I(COI)部分序列进行了测定和分析,经比对获得578bp核苷酸片段,发现49个变异位点,得到35个单倍型,包括7个共享单倍型,各群体都具有较好的单倍型多态性和核苷酸多态性,其中鄱阳湖群体遗传多样性相对最高。AMOVA分析表明,五群体间总遗传分化系数Fst=0.3187(P<0.05),群体间具有较高的遗传分化。MEGA3.1软件计算五群体的Kimura2-paramter遗传距离,洞庭湖群体和巢湖群体之间的遗传距离最远为0.0191,巢湖群体和洪泽湖群体之间的遗传距离最近为0.0051。以同属胖掌沼虾(Macrobrachium inflatum)为外群分别构建了NJ和UPGMA系统树,结果显示洞庭湖和鄱阳湖为一族群,太湖、巢湖和洪泽湖为一族群。
