摘      要：Primers based upon the mitochondrial genome sequences of Bos taurus were used to amplify and sequence the complete mitochondrial D-loop region of Jiulong yak(Poephagus grunniens).The results showed that the length of D-loop was 893 bp,with 87.4%homology to the Bos taurus D-loop sequence;there were 17 bp *** Ovis aries as an outgroup,the phylogeny of representative species of Bovinae(***,***,Bos taurus,Bos indicus,Bison bison,Bison bonasus,and Bubalus bubalis)was *** Bovinae,the sequence divergence between ***,*** and American bison(Bison bison)was 6.2%-6.8%,which was less than that of Bos taurus and Bos indicus within Bos(10.0%-11.3%).Phylogenetic analysis found that ***,*** and Bison bison clustered first of all,indicating there was higher genetic comparability among them than to that of *** data from paleontology,morphology,and molecular biology,the present analysis supports the argument that Poephagus grunniens and Poephagus mutus should be classified as a distinct genus in Bovinae,that is Poephagus.
