| 摘 要： | 研究测定了天牛科3亚科9种昆虫线粒体16S rDNA基因约500bp的序列,对序列的碱基组成和遗传距离进行分析。并基于16S rDNA基因序列数据,采用邻接法(NJ)和最大简约法(MP)分析天牛科3亚科分子系统发育关系。研究结果表明,2种方法得到的分子系统树其分支结果一致,可将内群分为2个分支,第1个分支包括沟胫天牛亚科和天牛亚科;第2个分支包括花天牛亚科。16SrDNA基因对天牛科亚科间系统发育的研究是有价值的。

| Abstract: | Phylogenetic relationships among 9 species in 3 subfamilies of Cerambycidae were investigated using partial mitochondrial 16S rDNA sequence data. Sequence data were analyzed by using MEGA. Phylogenetic trees were reconstructed using neighbor-joining and maximum-parsimony methods and showed similar topology. The ingroups were divided into two clades. One clade consisted of Lamiinae and Cerambycinae. The other clade was composed of Lepturinae. Results suggest that mitochondrial 16S rDNA is a viable genetic ma... |
