基于线粒体16S rRNA基因的14种造礁石珊瑚系统发育关系分析
Phylogenetic Analysis for 14 Species of Reef-building Corals Based on 16S rRNA genes
摘要
Abstract
Partial sequences of 16S rRNA from 14 species of reef-building coralsin Dalajia Island and Xiaolajia Island were amplified and sequenced, and Base ratio and genetic distances were analyzed. The result indicated that the average A+T of this region accounted for 63.5% from 14 species; A+T contents of 16S rRNA fragments werehigher than G+C obviously. The sequences of 16S rRNA fragments had a high degree of saturation.The average genetic distance was 0.179 from 14 species.According to the Neighbour-joining,Maximum-likelihood and Minimum-evolution trees,the separated Faviidae was the root clade, and the second clade was composed of Agariciidae, Acroporidae,Poritidae and Oculinidae.TheHydnophora exesa of Merulinidae merged into the Faviidae.The result suggested that morphological classification may be limited by coral skeletons plasticity.关键词
