| 摘 要： | 贻贝隶属于软体动物门(Mollusca)、双壳纲(Bivalvia)、翼形亚纲(Pteriomorphia)、贻贝目(Mytilida)、贻贝超科(Mytiloidea),大约有400种贻贝分布在世界各地,可适应淡水、潮间带至深海多种生境。本实验以贻贝科6亚科12属28种中国沿海常见贻贝的28SrDNA为目的片段,构建系统发育进化树,运用最大似然法和贝叶斯推演法分析了贻贝科的系统发生,并追踪贻贝科物种系统演化历史。结果显示:贻贝亚科Mytilinae、偏顶蛤亚科Modiolinae、石蛏亚科Lithophaginae均非单系群。在属阶元,深海偏顶蛤属Bathymodiolus、贻贝属Mytilus和股贻贝属Perna为单系群。本研究发现应接受将原隔贻贝属Septifer分为Septifer属和Mytilisepta属的分类提议;应接受将原石蛏属Lithophaga中的膜石蛏亚属Leiosolenus提升至属的地位的分类提议。此外,短齿蛤属Brachidontes的单系性不被支持,刻缘短齿蛤Brachidontessetiger并未与短齿蛤属其他物种在系统发育树上聚拢,亲缘关系较远,为不同属物种,建议恢复刻缘短齿蛤原属名Volsella (Dunker, 1857)。

| Abstract: | There are about 400 species of marine mussel (Mollusca:Bivalvia:Pteriomorphia:Mytilida:Mytiloidea:Mytilidae) living all over the world, and they adapt to the highly variable habitats in both intertidal zone and deep sea. In this study, 28S rDNA gene of species in this family along Chinese coasts were collected and phylogenetic trees were reconstructed by maximum likelihood and Bayesian inference methods. The results showed that subfamilies Mytilinae, Modiolinae, and Lithophaginae were not monophyletic groups. At genus level, Bathymodiolus, Mytilus, and Perna are monophyletic groups. The result supports the new classification scheme for genus Septife that should be divided into Septifer and Mytilisepta and the elevation of subgenus Leiosolenus (belonging to genus Lithophaga) to genus level. However, the monophyly of genus Brachidontes is not supported. The Brachidontes setiger has larger genetic distance from other species in the genus and they did not form a single clade in phylogenetic trees. Therefore, it is suggested Brachidontes setiger belongs to a different genus and we should still use its original genus name, Volsella (Dunker, 1857). |
