The complete mitochondrial genome of S. caldwelli was determined in this study. The gene composition, arrangement and transcriptional orientation in S. caldwelli mitogenome were identical to most vertebrates. Two start codon patterns (ATG and GTG) and three stop codon patterns (TAG, TAA and T) were found in protein-coding genes. Only the tRNA-Ser2 could not fold into a typical clover-leaf secondary structure for lacking the dihydrouridine arm. Sequences alignment results suggest that the complete mitogenome of S. caldwelli is an efficient tool to check species identification by comparing different gene sequences.
本研究测定了考德威尔氏菌的完整线粒体基因组。考德威尔氏菌线粒体基因组中的基因组成、排列和转录方向与大多数脊椎动物相同。在蛋白质编码基因中发现了两种起始密码子模式（ATG和GTG）和三种终止密码子模式（TAG、TAA和T）。只有tRNA-Ser2因缺乏二氢尿苷臂而无法折叠成典型的三叶草叶形二级结构。序列比对结果表明，考德威尔氏菌的完整线粒体基因组是通过比较不同基因序列来检验物种鉴定的有效工具。
