摘要
应用对数关联距离与互信息距离加权的方法,对完全基因组DNA序列和蛋白质序列构建了30种细小病毒系统发育树。构建的发育树均将30种细小病毒分成细小病毒亚科和浓核病毒亚科两个大的分枝,其结构与国际病毒学分类委员会第八版报道的结果及已有文献的结果基本一致。且基于蛋白质序列构建的系统发育树比基于完全基因组DNA序列构建的要好。
The phylogenetic trees of 30 parvoviruses are reconstructed by the weighted methods of log-correlation distance and mutual information distance. The trees are made of two branches of parvovirinae and densovirinae, and the structures are mainly consistent with the eighth report of the International Committee on Taxonomy of Viruses and results of the existing literature. The tree based on the protein sequences construction is better than that based on entire genome DNA sequences construction.
