摘要
本文测定丽棘蜥12SRNA、16SRNA、Cyt b基因部分序列,并从GenBank中下载15种有鳞目动物的同源序列,以鳄目的2个种(Alligator sinensis和Cairman crocodilus)作为外群,构建MP、NJ和ML分子系统树,探讨它们的系统发育关系。MP、NJ和ML分子系统树聚类的结果显示:蛇蜥亚目、壁虎亚目、蚓蜥亚目、石龙子亚目和鬣蜥亚目能够完全分开,蛇亚目和蜥蜴亚目在有鳞目中为姐妹支关系。
Mitochondrial gene fragments of 12SRNA,16SRNA and Cyt b of Acanthosaura lepidogaster were amplified and sequenced.Combining these with the homologous sequences of 15 species from GenBank and using 2 species of the Crocodylia as the outgroups,the molecular phylogenetic trees of these groups were reconstructed with neighbor-joining （NJ） maximum-parsimony （MP） and maximum likelihood （ML） methods.The results indicated that Anguimorpha,Gekkota,Amphisbaenia,Scincomorpha,and Iguania are separated from each other in the molecular phylogenetic trees.Within the Squamata,a sister group between Serpentes and Sauria was recovered by NJ,MP and ML analyses.
