| 摘 要： | 在最新GenBank分子信息的汇集、分析基础上,利用小亚基单位核糖体RNA基因序列分别构建了最大简约树、距离树、最大似然树及贝叶斯树,对长期存在争议的游仆目纤毛虫的系统关系进行了探讨和修订.工作显示:1)游仆目不是1个单源发生系;2)盘头虫类从游仆目中较早分化出来,呈现与排毛类、寡毛类平行的进化关系;3)腹棘虫科内的腹棘虫和拟游仆虫体现了密切的亲缘关系;4)游仆虫科、舍太虫科、檐纤虫科在所有分子树中均表现了十分稳定的拓扑结构;5)游仆虫属内可以细分为7个亚类群;6)尾刺虫科在游仆目内分化较早,支持前人有关其在系统演化时序中处于原始阶段的论断. |

| Abstract: | Euplotids are among the best known and most readily recognized ciliates,which have been for a long time regarded as a monophyletic lineage.The order Euplotida contains several well-known taxa,e.g.Euplotes,Diophrys,Uronychia,Aspidisca,Gastrocirrhus,and Discocephalus etc.However,the phylogenetic relationships among them still remain confusing considering their evolutionary process and systematic positions of many groups due to the high diversity of the morphology and lacking molecular data.Phylogenetic trees ... |
