测定了一种溪栖蛙Paramegophrys oshanensis的线粒体全基因组。该有丝分裂基因组全长17,747 bp，包含13个蛋白质编码基因、2个rRNA基因、22个tRNA基因和一个控制区（D-loop）。轻链的碱基组成为28.77%A、29.85%T、26.26%C和15.11%G。与大多数其他脊椎动物相比，这种有丝分裂基因组具有一些不同的特征：tRNA-Met基因的非串联重复（形成tRNA-Met 1和tRNA-Met 2基因），tRNA-Trp基因被从WANCY簇易位到Cytb基因后部的72-bp非编码区替换，tRNA-Val基因从16 S rRNA前部易位到tRNA-Met 1基因后部，以及tRNA-Pro基因从D-loop区的前部易位到tRNA-Met 2基因的前部。在D-loop区检测到3种长度为71 ~ 92 bp的串联重复序列。
The complete mitochondrial genome of a stream-dwelling frog species Paramegophrys oshanensis was determined. This mitogenome was 17,747 bp in length, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region (D-loop). The base composition of the light strand was 28.77% A, 29.85% T, 26.26% C, and 15.11% G. Compared with most other vertebrates, this mitogenome has some different features: a non-tandem duplication of tRNA-Met gene (forming tRNA-Met1 and tRNA-Met2 genes), the replacement of tRNA-Trp gene by a 72-bp noncoding region translocated from the cluster of WANCY to the back of Cytb gene, the translocation of tRNA-Val gene from the front of 16S rRNA to the back of tRNA-Met1 gene, and the translocation of tRNA-Pro gene from the front of D-loop region to the front of tRNA-Met2 gene. Three kinds of tandem repeats with size ranging from 71 to 92 bp were detected within D-loop region.
