| 摘 要： | 通过对云南省昆明市禄劝地区30只中缅树鼩(Tupaia belangeri)细胞色素b(Cytochrome b,Cyt b)基因全序列(1 140 bp)的遗传分析,对禄劝地区中缅树鼩;Cyt b基因特征进行初步探讨.结果表明,禄劝地区中缅树鼩Cyt b基因包含32个核苷酸变异位点,占全序列的2.81%,其转换/颠换为10.4.基于Cyt b基因的遗传距离构建的分子系统树显示,本实验研究的中缅树鼩是一个独立的分类单位而非普通树鼩(T.glis)的亚种;同时显示攀鼩目(Scandentia)与皮翼目(Dermoptera)亲缘关系较近.

| Abstract: | To clarify the genetic character of Tupaia belangeri from Luquan District,Kunming,we examined DNA sequence variations in the mitochondrial cytochrome b gene gotten from 30 individuals.We detected variation at 32 nucleotide sites(2.81% in the full sequences),the rate of transitions and transversions is 10.4.T.belangeri was a valid taxonomic species rather than a sub-species of T.glis based on Cyt b gene sequences;the relationship between order Scandentia and Dermoptera was closer. |
