The complete mitochondrial genome was sequenced from a viviparous toad-headed agama, Phrynocephalus forsythii, which is endemic to the Taklamakan Desert. The mitogenome sequence was 17,542 bp in size, containing 13 protein-coding genes, 22 tRNA genes, two rRNA genes and a control region (D-loop). The gene arrangement and composition of P. forsythii is identical to the mitogenome of P. theobaldi in that tRNA-Pro was translocated immediately downstream of tRNA-Phe. The D-loop comprised two parts, one existing between tRNA-Thr and tRNA-Phe, and another containing 12 copies of 36-bp tandem repeats inserting between tRNA-Pro and 12S rRNA. The complete mitogenome sequence of P. forsythii may provide fundamental data for unveiling the phylogenetic origin and adaptive evolution related to Phrynocephalus viviparity.
对一种胎生沙蜥——荒漠沙蜥（Phrynocephalus forsythii）的完整线粒体基因组进行了测序，该物种是塔克拉玛干沙漠特有的。线粒体基因组序列大小为17,542 bp，包含13个蛋白质编码基因、22个tRNA基因、两个rRNA基因和一个控制区（D环）。荒漠沙蜥的基因排列和组成与西藏沙蜥（P. theobaldi）的线粒体基因组相同，即tRNA-Pro移位到tRNA-Phe的紧邻下游。D环由两部分组成，一部分存在于tRNA-Thr和tRNA-Phe之间，另一部分包含12个36 bp串联重复序列的拷贝，插入在tRNA-Pro和12S rRNA之间。荒漠沙蜥的完整线粒体基因组序列可能为揭示与沙蜥胎生相关的系统发育起源和适应性进化提供基础数据。
