基于CO Ⅰ和Cyt b基因序列的凤蝶科六属分子系统学研究
Molecular systematics of six genera of Papilionidae (Lepidoptera) based on mitochondrial cytochrome oxidase I and Cyt b gene sequences
摘要
Abstract
Partial sequences of CO I genes of 25 species and Cyt b genes of 20 species in six genera of Papilionoidea were sequenced and analyzed for exploring their phylogenetic relationships. Adoxophyes honmai was used as outgroup to reconstruct the phylogenetic trees of six genera with neighbor-joining ( NJ),maximum parsimony (MP) and Bayesian inference (BI) methods. The results indicated that CO I genes are 661 bp in length by alignment, including 417 conserved, 244 variable and 191 parsimonious-informative sites, and the average percentage of A + T is 70.3％, much higher than that of C + G (29.6％). The Cytb genes are 433 bp in length by alignment, including 239 conserved, 194 variable and 135 parsimoniousinformative sites; and the average percentage of A + T is 74. 2％, much higher than that of C + G (25.7％). The molecular phylogenetic trees showed that the genera Papilio, Chilasa, Bhutanitis,Pachliopta and Teinopalpus are all monophyletic clades and separated from each other in the molecular phylogenetic trees. The results correspond with the classification based on traditional morphological characters. However, the monophyletic position of the genus Graphium is not certain and needs further study. The results accumulated data for the molecular systematic study of the family Papilionidae in China.关键词
