摘要： 采用PCR扩增方法测定红腹锦鸡Chrysolophus pictus线粒体基因组全序列:序列全长16 678 bp,共有13个蛋白质编码基因、2个rRNA基因和22个tRNA基因。基因组的组成、顺序、编码链的选择、tRNA的结构都与绝大多数鸟类相同或相近。红腹锦鸡线粒体基因组碱基组成分别为:A(30.4%)、T(24.8%)、C(31.2%)、G(13.6%)。总的A+T含量为55.2%。除了COⅠ基因起始密码子是GTG,其余12个蛋白质编码基因的起始密码子都是ATG。tRNA基因核苷酸长度为65～76 nt,12S rRNA 和16S rRNA基因分别为968和1 604 nt。

Abstract: The complete mitochondrial genome of Chrysolophus pictus was sequenced by PCR amplification.The entire mtDNA sequence was 16 678bp in length and contained 13 protein-coding genes,2 rRNA genes,22 tRNA genes,anda control region (D-loop).Its gene arrangement pattern was identical with thoseof other avian.The average nucleotide composition was:30.4% of A,24.8% of T,31.2% of C,13.6% of G.All protein-coding genes initiated with ATG,except for COI,which began with GTG.Transfer RNA genes ranged in length from 65 to 76 nt.The12S rRNA and 16S rRNA genes in C.pictus were 968 and 1 604 nucleotides long.

Key words: Chrysolophus pictus, Phasianidae, mitochondrialgenome
