Abstract

In this study, the complete mitochondrial genome of Sorex minutissimus was sequenced and deposited to GeneBank for the first time using muscle tissue. This mitochondrial genome is a circular molecule of 16,700 bp in length and sequence analysis showed it contains 2 rRNA genes, 22 tRNA genes, 13 protein-coding genes, rep_origin, and D_loop. Phylogenetic analysis on the basis of 12 protein-coding genes except ND6 of 13 Soricidae species’ mitochondrial genomes using ML and BI demonstrated that S. minutissimus and other Sorex species were clustered into same clade.

Sorex minutissimus（Eulipotyphla：Soricidae）的完整线粒体基因组

摘要

在这项研究中，对Sorex minutissimus的完整线粒体基因组进行了测序，并首次使用肌肉组织将其沉积到了GeneBank中。该线粒体基因组是一个16700 bp的环状分子，序列分析表明它包含2个rRNA基因，22个tRNA基因，13个蛋白质编码基因，rep_origin和D_loop。用ML和BI技术对13个狼蛛科线粒体基因组中除ND6外的12个蛋白质编码基因进行了系统进化分析，结果表明细小沙门氏菌和其他Sorex物种都聚集在同一进化枝上。
