Xiaoxiang chicken () is one of the native breeds in the Southeastern of Guizhou province, China. The complete mitochondrial genome sequence of Xiaoxiang chicken (small-sized breed chicken) was obtained for the first time. The mitogenome is 16,784 bp in length, and it contained a D-loop region, two rRNA genes, 13 protein-coding genes, and 22 tRNA genes. A neighbour-joining phylogenetic tree was structured based on the D-loop, which indicated that the Red junglefowl was the direct ancestor of Xiaoxiang chicken, and both were closed to the Silky chicken and Dongan black chicken.
小香鸡是中国贵州省东南部的本土品种之一。首次获得了小香鸡（小型品种鸡）的完整线粒体基因组序列。该线粒体基因组长度为16,784 bp，包含一个D-loop区域、两个rRNA基因、13个蛋白质编码基因和22个tRNA基因。基于D-loop构建了邻接系统发育树，结果表明原鸡是小香鸡的直接祖先，且二者与丝羽乌骨鸡和东安黑鸡亲缘关系较近。
