    abstract = {The gayal (<I>Bos frontalis</I>) is a rare semi-wild and semi-domestic bovine species. There still have remarkable  divergences  on the gayal’s origin and taxonomic status. In the present study, the cytochrome b (<I>Cyt b</I>) gene partial sequences (447 bp) of 13 gayals were sequenced and analyzed. Combined with the homologous fragments of other bovine <I>Cyt b</I> sequences cited in GenBank, the phylogenetic trees of genus Bos were reconstructed by Neighbor-Joining (NJ) and Maximum Parsimony (MP) methods with <I>Bubalus bubalis</I> as outgroup. Sequence analysis showed that, among he 447 sites compared for 13 gayals, 33 variable sites (7.38% of all sites) and 4 different haplotypes were observed, showing abundant mitochondrial genetic diversity in gayals. Both NJ and MP trees demonstrated that gayals in this study were markedly divided into 3 embranchments: One embranchment clustering with <I>Bos gaurus</I>, another clustering with<I> Bos taurus</I> and the third clustering with<I> Bos indicus</I>. The results of phylogenetic analysis suggested that the gayal might be the domesticated form of the gaur and a great proportion of the gayal bloodline was invaded by other bovine species.}
