Abstract

The complete mitochondrial genome of the Littorina brevicula was determined in this study. The complete mitogenome (mtDNA) is 16,356 base pairs (bp) in length and contains 13 protein-coding genes, two rRNA genes, and 22 tRNA genes. The control region was divided into two parts. The overall base composition of the genome in descending order was 35.33%—T, 28.41%—A, 20.43%—C, and 15.81%—G. In 13 protein-coding genes, 12 genes start with ATG, except nad5 starts with ATT. For the stop codon, seven genes end with TAA, atp6, nad41, and nad3 end with TAG. Phylogenetic analysis indicated that L. brevicula is close to Naticidea family. This study first determined the complete mitochondrial genome of L. brevicula. It would be a supplement for the genetic analysis of L. brevicula and promote the phylogenetic of Littorinidea.

摘要

在这项研究中确定了短立陶宛的完整线粒体基因组。完整的有丝分裂基因组（mtDNA）长度为16,356个碱基对（bp），包含13个蛋白质编码基因，2个rRNA基因和22个tRNA基因。对照区域分为两部分。基因组的总体碱基组成按降序排列为35.33％-T，28.41％-A，20.43％-C和15.81％-G。在13个蛋白质编码基因中，有12个基因以ATG开头，但nad5以ATT开头。对于终止密码子，七个基因以TAA结尾，atp6，nad41和nad3以TAG结尾。系统发育分析表明L. brevicula接近Naticidea家庭。这项研究首先确定了短乳杆菌线粒体的完整基因组。这将是短乳杆菌基因分析的补充 并促进Littorinidea的系统发育。
