摘要

我们利用Illumina软件对森林小圆蝽线粒体基因组进行了测序，发现了一个16534 bp的环状基因组，包含13个蛋白质编码基因（PCGs）、22个trna、2个rrna、1个d环和OL。碱基组成：32.95% A, 28.63% T, 26.14% C, 12.28% g。25种Sciuridae种的系统发育分析表明，sciurrotamias forresti和sciurrotamias davidianus之间存在较深的分裂，比其他属之间的分裂更远。这一结果支持了森林杉木可以作为一个属的观点，并表明有必要进行进一步的研究，结合形态比较和分化年代测定来重新评估其分类地位。

The complete mitochondrial genome of the Forrest's rock squirrel (Sciurotamias forresti, Rodentia: Sciuridae) and its phylogenetic implication.

We sequenced the whole mitochondrial genome of Sciurotamias forresti using Illumina, revealing a 16,534 bp circular genome with 13 protein-coding genes (PCGs), 22 tRNAs, 2 rRNAs, a D-loop, and OL. Base composition: 32.95% A, 28.63% T, 26.14% C, 12.28% G. Phylogenetic analysis of 25 Sciuridae species showed a deep split between Sciurotamias forresti and Sciurotamias davidianus, more distant than those between other genera in the subfamily Xerinae. This supports the notion that Sciurotamias forresti may be ranked as a genus and indicated the necessity of further studies integrating morphological comparison and divergence dating to reevaluate its taxonomic position.
