摘要
测定了四川黄牛5个品种的线粒体细胞色素b部分片段(420 bp)42个个体以及28个个体线粒体DNA控制区(D-loop)的全序列,结合已报道的中国8个黄牛品种22个个体的线粒体DNA控制区(D-loop)全序列,分析结果表明:四川黄牛的部分Cyt b基因片段有5个变异位点,7种单倍型可分为以2个单倍型为主的2大类型;线粒体DNA控制区检测到64个变异位点,28种单倍型,单倍型H1～H23为普通黄牛类型,单倍型H24～H28为瘤牛类型的单倍型.在四川黄牛中,67.86%为普通牛类型,32.14%为瘤牛类型.研究结果表明四川黄牛主要有2类母系来源.
This study sequenced partial sequences of mitochondrial DNA Cyt b gene （420 bp） of 42 individuals and D-loop region （910 bp） of 28 individuals in 5 cattle breeds from Sichuan Province. The results showed that there were 5 mutation sites among the partial Cyt b gene and 7 haplotypes, which was divided into two main types. There were 64 mutation sites and 28 haplotypes defined in D-loop region when the 22 published Chinese cattle D-loop sequences aligned together with the data in this study. Haplotype H1 -H23 was belonging to Bos. Taurus type while Bos. Indicus type contained haplotypes from H24 to H28. 67.86% individuals were Bos. Taurus type and 32.14% were Bos. Indicus type in Sichuan cattle breeds. It suggested that the Sichuan cattle were mainly origined from Bos. Taurus type and Bos. Indicus type.
