The complete DNA sequence of the mitochondrial genome of the bullsnake ( sayi) is presented and analyzed in this study. The genome is 17,193 bp in length, and contains 22 transfer RNA genes, 2 ribosomal RNA genes, 13 protein-coding genes and 2 control regions. The overall base composition of the H-strand is A (34.5%), T (26.2%), C (25.8%) and G (12.7%). The gene order and orientation of the mitogenome is consistent with other sequenced genomes from colubrid snakes. Phylogenetic analyses using the ML, NJ and MP methods for a set of colubrids, including every sequenced genus within the sub-family Colubrinae, produced identical trees. We show that is most closely related to the American ratsnake genus
本研究展示并分析了牛蛇（Sayi）线粒体基因组的完整DNA序列。该基因组长度为17,193 bp，包含22个转移RNA基因、2个核糖体RNA基因、13个蛋白质编码基因和2个控制区。重链的总体碱基组成为A（34.5%）、T（26.2%）、C（25.8%）和G（12.7%）。有鳞目蛇类线粒体基因组的基因顺序和方向与其他已测序的基因组一致。使用最大似然法（ML）、邻接法（NJ）和最大简约法（MP）对一组有鳞目蛇类进行系统发育分析，包括游蛇亚科内每个已测序的属，得到了相同的树状图。我们发现 与美洲鼠蛇属关系最为密切。
原文中“ We show that is most closely related to the American ratsnake genus”这里的“ ”部分缺失具体内容。
