The whole mitogenome of the freshwater fish Channa diplogramma (Malabar snakehead), a vulnerable species of snakehead from the Western Ghats, India was sequenced for the first time. The genome is 16,571 bp in length, comprised of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a non-coding control region. All the protein-coding genes, tRNA and rRNA were located in the heavy strand except nad6 and 8 tRNAs (Glutamine, Alanine, Asparagine, Cysteine, Tyrosine, Serine, Glutamic acid and Proline) transcribed from L strand. The genome exhibited an overlapping of 7 bp in 2 different locations from 8100 to 10,342 bp. These overlaps were detected between protein-coding genes (atp8 – atp6, nad4l – nad4). In addition, intergenic spacers of 167 bp were also present. The overall GC- and AT-skews of the H-strand mitogenome were 0.1077 and − 0.2439, respectively revealing that the H-strand had equal amounts of A and T and that the overall nucleotide composition was C skewed. All tRNA genes had cloverleaf secondary structures, while the secondary structure of tRNA^Ser lacked a discernible dihydrouridine stem. The phylogenetic analysis of C. diplogramma shows its close similarity to C. micropeltes, native to Southeast Asia, Malay Peninsula and Indonesia.

淡水鱼类Channa diplogramma（马拉巴尔蛇头）（一种来自印度西高止山脉的脆弱蛇头物种）的整个有丝分裂基因组首次测序。基因组长度为16571 bp，由13个蛋白质编码基因，2个rRNA基因，22个tRNA基因和一个非编码控制区组成。除了从L链转录的nad6和8个tRNA（谷氨酰胺，丙氨酸，天冬酰胺，半胱氨酸，酪氨酸，丝氨酸，谷氨酸和脯氨酸）外，所有蛋白质编码基因，tRNA和rRNA均位于重链中。基因组在8100至10,342 bp的2个不同位置显示了7 bp的重叠。在蛋白质编码基因（atp8 – atp6，nad4l – nad4）之间检测到了这些重叠）。另外，还存在167bp的基因间间隔子。H链有丝分裂基因组的总体GC和AT偏斜分别为0.1077和-0.2439，这表明该H链具有相等的A和T量，并且总核苷酸组成为C偏斜。所有的tRNA基因都具有苜蓿叶状二级结构，而tRNA ^Ser的二级结构缺少可分辨的二氢尿苷茎。C. diplogramma的系统发育分析表明，它与原产于东南亚，马来半岛和印度尼西亚的C. micropeltes非常相似。
