研究新疆东部和西部不同地理种群意大利蝗Calliptamus italicus(L.)线粒体基因中16SrDNA序列差异。结果表明:(1)意大利蝗A+T的含量(67.7%)明显高于G+C的含量(32.3%);(2)多重序列比对和UPGMA系统发育树的结果表明新疆东、西部不同地理种群的意大利蝗的遗传变异极小。
Partial sections of the mitochondrial 16S rDNA of Calliptamus italicus(L.) from different geographic populations of Xinjiang Province were compared.The results show that:1) The percentage of A + T(67.7%)of C.italicus was more than G + C(32.3%);2) Multiple sequence alignment and the UPGMA phylogenetic tree indicate that different geographic populations of C.italicus display almost no genetic difference.
