摘要为了阐明欧亚大陆鼬属（Mustelidae，Carnivora）种间的分子系统发育关系，我们测定了线粒体细胞色素B基因全序列（1，140 bp）。用邻接法和最大似然法构建的分子系统树显示了物种间的共同拓扑关系。美国水貂M. vison首先分支出来，并与其他种类的Mustela相距甚远。不包括M. vison，白鼬M.蚯蚓首先从其他物种中分裂出来。两只身体大小的小黄鼠狼，最小的黄鼠狼M。nivalis和山鼬M.阿尔泰，包括一个集群（命名为“小黄鼠狼组”）。其他物种形成了另一个集群，其中家庭雪貂M。furo，欧洲臭鼬M. putorius和草原臭鼬M. eversmanni被注意到具有87-94%的自展值（命名为“雪貂群”），支持雪貂是从M. putorius和/或M.埃弗斯曼尼欧洲水貂M. lutreola是最接近雪貂组的。西伯利亚鼬M. sibirica和日本鼬M. itatsi对应种间水平的差异，而两种与M. lutreola和雪貂组。这些结果为了解鼬的进化以及调查本地物种和引进物种之间的杂交状况提供了宝贵的见解。
Abstract To illuminate molecular phylogenetic relationships among Eurasian species of the genus Mustela (Mustelidae, Carnivora), we determined nucleotide sequences of the complete mitochondrial cytochrome b gene region (1,140 base pairs). Molecular phylogenetic trees, constructed using the neighbor-joining and the maximum likelihood methods, showed the common topology of species relationships to each other. The American mink M. vison first branched off and was positioned very remotely from the other species of Mustela. Excluding M. vison, the ermine M. erminea first split from the rest of the species. Two small body-sized weasels, the least weasel M. nivalis and the mountain weasel M. altaica, comprised one cluster (named “the small weasel group”). The other species formed another cluster, where the remarkably close relationships among the domestic ferret M. furo, the European polecat M. putorius, and the steppe polecat M. eversmanni were noticed with 87–94% bootstrap values (named “the ferret group”), supporting the history that the ferret was domesticated from M. putorius and/or M. eversmanni. The European mink M. lutreola was the closest to the ferret group. The genetic distance between the Siberian weasel M. sibirica and the Japanese weasel M. itatsi corresponded to differences of interspecific level, while the two species were relatively close to M. lutreola and the ferret group. These results provide invaluable insight for understanding the evolution of Mustela as well as for investigating the hybridization status between native and introduced species for conservation.
