| 摘 要： | 测定并比较了扭蚌和反扭蚌的ITS-1序列，以三角帆蚌为外类群，利用Mega2．0软件中的最大简约法（MP法）和邻接法（NJ法）构建它们的系统发育树，试验结果表明，扭蚌和反扭蚌聚在一起形成一分支，三角帆蚌形成另一独立的分支；由此推断，扭蚌和反扭蚌属同物异名。

| Abstract: | The phylogenetic relationship between Arconaia lanceolata and A.mutica was investigated using sequences of the first internal transcribed spacer region(ITS-1) of ribosomal DNA(rDNA).The phylogenetic tree was assessed using Neighbor-joining(NJ) and maximum parsimony(MP) analyses.No variations were found in the phylogenies created by the two methods.The results suggest that Arconaia lanceolata and A.mutica are probably the same species. |
