摘要
测定并比较了三角帆蚌(Hyriopsis cumingii)和许氏帆蚌(Hyriopsis schlegerii)的ITS-1序列,以背瘤丽蚌(Lamprotula leai)为外类群,利用PHYLIP3.65软件中的最大简约法和邻接法构建了它们的系统发育树。结果表明,许氏帆蚌和三角帆蚌没有表现出种间差异,应属于同一物种。
The taxonomical status of Hyriopsis cumingii and Hyriopsis schlegerii was investigated using sequences of the first internal transcribed spacer region （ ITS - 1 ） of ribosomal DNA （rDNA）. The affiliation of them was assessed by Neighbor-joining （NJ） and maximum parsimony （MP） analyses. The results show approximately consistent between NJ tree and MP tree. It suggests that Hyriopsis cumingii and Hyriopsis schlegerii be same species.
