竹鸡属包括灰胸竹鸡（Bambusicola thoracica）和棕胸竹鸡（B. fytchii）两种鸟类。两种竹鸡线粒体基因组全长为16726 bp，包含13个蛋白编码基因、22个tRNA、2个rRNA和1个控制区。基因排列顺序与红原鸡（Gallus gallus）一致，属于典型的鸟类排列顺序；碱基组成存在明显的AT偏向性。两种竹鸡线粒体基因组的13个蛋白质编码基因的序列长度和终止密码子都完全一样，但部分编码基因的起始位置以及起始密码子存在差异；两种竹鸡的线粒体基因组基因排列紧密；两种竹鸡线粒体全基因组序列之间共有1132个变异位点，其中缺失位点24个，遗传距离为0.071。
THE STRUCTURE OF COMPLETE MITOCHONDRIAL GENOME AND ITS COMPARISON BETWEEN BAMBUSICOLA THORACICA AND B. FYTCHII
Two species of Bambusicola were recognized as B. thoracica and B. fytchii. The entire mitochondrial genome of the two species is 16,726 bp in length, which contains 13 protein coding genes (PCGs), 22 tRNA, 2 rRAN, and one control region. The mitochondrial genomic organization and gene order are consistent with that of Gallus gallus, belonging to typical gene order within birds, and the base composition exists obviously AT bias. The sequence length and teminator codon of the 13 PCGs of two species are just the same, but the initial position and codon of some PCGs are different. There are 1132 variable sites between the two species with 24 deletes among which, and the genetic distance between the two species is 0.071.
