Abstract

The first complete mitochondrial genome sequence of Phrynocephalus viviparity was determined for the toad-headed lizard Phrynocephalus theobaldi orientalis. The 16,608 bp mitogenome contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 2 control regions (CRs). The overall base composition of H-strand is T: 26.7%, C: 24.5%, A: 37.6%, G: 11.2%. The gene arrangement and composition of P. theobaldi orientalis was similar to other published mitochondrial genomes of Phrynocephalus oviparity, except that tRNA-Phe and tRNA-Pro were exchanged. The control region comprised two parts, one between tRNA-Thr and tRNA-Phe and another between tRNA-Pro and 12S RNA. The complete mitogenome sequence of P. theobaldi orientalis provided fundamental data for resolving phylogenetic and genetic problems related to Phrynocephalus viviparity.

摘要

已测定东方沙蜥(Phrynocephalus theobaldi orientalis)的首个完整线粒体基因组序列,该沙蜥为胎生沙蜥(Phrynocephalus viviparity)。这个16,608 bp的线粒体基因组包含13个蛋白质编码基因、2个rRNA基因、22个tRNA基因和2个控制区(CRs)。重链的总体碱基组成为:T占26.7%、C占24.5%、A占37.6%、G占11.2%。东方沙蜥的基因排列和组成与其他已发表的卵生沙蜥线粒体基因组相似,只是tRNA-Phe和tRNA-Pro发生了交换。控制区由两部分组成,一部分在tRNA-Thr和tRNA-Phe之间,另一部分在tRNA-Pro和12S RNA之间。东方沙蜥的完整线粒体基因组序列为解决与胎生沙蜥相关的系统发育和遗传问题提供了基础数据。
