Abstract

We determined the complete mitochondrial genome of Lactoria cornuta, which is 16,495 bp in length with an A + T content of 57.37%, and contains 13 protein-coding genes, 2 rRNAs, 22 tRNAs and a complete control region. The total base composition of the mitogenome is 28.2% T, 26.7% C, 29.2% A and 15.9% G. Of the 13 protein-coding genes, 12 genes start with an ATG codon, except for COX1 with GTG. Ten genes use TAA or AGA as the termination codon, whereas three (COX2, ND4, and Cyt b) have incomplete stop codon T. This study would provide useful genetic information for phylogenetic and species idenfication of the family Ostraciidae.

摘要

我们确定了Lactoria cornuta的完整线粒体基因组，全长16,495 bp，A + T含量为57.37％，包含13个蛋白编码基因，2个rRNA，22个tRNA和完整的控制区。有丝分裂基因组的总碱基组成为28.2％T，26.7％C，29.2％A和15.9％G。在13个蛋白质编码基因中，除了带有GTG的COX1外，还有12个基因以ATG密码子开头。十个基因使用TAA或AGA作为终止密码子，而三个（COX2，ND4和Cyt b）具有不完整的终止密码子T。这项研究将为O科的系统发育和物种识别提供有用的遗传信息。
