摘　　要：从GenBank下载72条原鸡属线粒体全基因序列,分别利用线粒体D-loop、13个蛋白质编码基因及其氨基酸序列构建系统发育树,揭示五华三黄鸡的分子进化.结果显示,基于D-loop的邻接树、蛋白质编码基因及其氨基酸的最大简约树的拓扑结构高度一致,五华三黄鸡与中国云南及缅甸分布的家鸡与红原鸡亚种聚为一枝,而与周边省份如江西省、湖南省、海南省几个鸡种的亲缘关系则较远,表明五华三黄鸡最有可能来源于中国云南.All 72 currently available complete mitochondrial sequences of Gallus retrieved from Gen Bank were used in phylogenetic analysis. The Neighbor-joining and Maximum parsimony trees,which are based on the D-loop,nucleotide dataset and the corresponding amino acid dataset of 13 protein-coding genes,have similar topology.The phylogenetic trees tree showed that Wuhua three-yellow chicken and Gallus in Yunnan province,Myanmar and Laos were clustered into one branch,separating from which in Jiangxi,Hunan and Hainan provinces. Our results suggest that Wuhua three-yellow chicken was the most likely origin of Yunan province,China.
