In this text, comparing the yak with other genus of Bovinae on paleontology evidence, morphologic character, blood protein polymorphism, microsatellite polymorphism, mtDNA sequence variance, rDNA RFLP data and sequence information of function gene, we find that the yak shows difference in Bos taurus, Bos indicus but close with Bison bison either in paleontology evidence, morphologic character or molecular biology character. So it was better to be considered as one independent genus Poephagus than to subgenus Poephagus or a species of Bos.

本文通过对牦牛与牛亚科其他属在古生物学证据、形态学特征、血液蛋白多态性、微卫星多态性、mtDNA序列变异、rDNA的RFLP数据和功能基因序列信息等各方面研究资料的比较分析，发现牦牛无论在古生物学证据、形态学特征，还是在分子生物学特征上均表现出与牛属中的普通牛Bos taurus、瘤牛Bos indicus不同，而与美洲野牛Bison bison的亲缘关系更近一些，因此将牦牛划分为牛亚科中1个独立属，似乎比将牦牛作为牛属中的1个亚属或1个种更合适。

Anguillarum isolates, while 94.3% and 91.9% nucleotide identical to L. pelagius and Photobacterium damselae respectively. MP analysis showed that ayu-H080701 shared 97.6%-98.8 % amino acid sequence identical to L. anguillarum isolates, while lower than 75.6 % to other bacteria. Phylogenetic analysis showed that ayu-H080701 grouped constantly with L. anguillarum isolates. The biochemical, physiological tests and sequence analysis all strongly supported the identification of the pathogen causing ayu vibriosis in Ninghai country, China, as an isolate of L.
