Abstract

The mitochondrial genome of Odorrana graminea was sequenced and analyzed. The complete mitochondrial genome is 18,106 bp in length, including 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, 21 transfer RNA genes, and a control region (D-loop). All PCGs are initiated by ATN codons, except for GTG for COI and ND5. Five PCGs use a common stop codon of TAA or TAG, whereas COI terminats with AGG as stop codon; ND6 with AGA; the other six ends with an incomplete stop codon (a single stop nucleotide T). The analysis results based on Bayesian inference method provide a useful resource for the phylogenetic studies of superfamily Ranoidea.

摘要

对Odorrana graminea的线粒体基因组进行了测序和分析。完整的线粒体基因组长度为18106 bp，包括13个蛋白质编码基因（PCG），2个核糖体RNA基因，21个转移RNA基因和一个控制区（D环）。除了用于COI和ND5的GTG，所有PCG都是由ATN密码子启动的。五个PCG使用TAA或TAG的共同终止密码子，而COI端接AGG作为终止密码子。带有AGA的ND6；其他六个末端带有不完整的终止密码子（一个终止核苷酸T）。基于贝叶斯推断方法的分析结果为超家族Ranoidea的系统发育研究提供了有用的资源。
