| 摘 要： | 根据位点特异性频率模型(site-specific rate model),利用PAUP软件,对线粒体COI基因序列不同密码子位点的数据模块分别进行了豉甲科和水生肉食亚目在亚科或科水平上的系统发育学分析,结果表明第二密码子数据模块获得的系统分析结果与形态学分析结果一致。表明位点特异性频率模型在线粒体COI基因作为标记来进行昆虫分子系统发育分析上获得了更好的效果。

| Abstract: | Comparison of different codon partition data schemes in phylogenetic tree construction demonstrated the advantage of second codon partition data in phylogenetic analyses at subfamily level for Gyrinidae and at family level for Hydradephaga, using PAUP or MrBayes with ME,MP,or ML criteria based on partial mitochondrial COI gene sequences.All optimal trees inferred using PAUP were obtained based on second codon partition data Trees inferred from morphological data supported the optimal trees.The results suggest the site-specific rate model(codon-partitioning schemes) is available approach to reconstruct insect phylogenetic trees based on partial mitochondrial COI gene sequences. |
