Abstract

Mitochondrial genomes in frogs are crucial in reconstructing phylogenetic relationships and clarifying molecular evolution in these animals. Therefore, we determined and analyzed the complete mitochondrial genome sequence of in this research. The total length of this sequence is 19,782 base pairs, containing a total of 37 genes, which include 22 tRNA genes, 13 protein-coding genes, and 2 rRNA genes, along with two D-loop regions. The mitochondrial genome exhibits a novel rearrangement pattern (tRNA--tRNA--CR1--CR2-tRNA-tRNA-tRNA) of genes. The nucleotide base composition of the mitochondrial genome consists of 32.51 % adenine (A), 31.32 % thymine (T), 21.95 % cytosine (C), and 14.21 % guanine (G), exhibiting a bias towards AT content (63.83 %). The phylogenetic tree is constructed using the Bayesian inference (BI) and maximum likelihood (ML) methods. The findings indicated a close relationship between and . The comprehensive mitochondrial genome of will be a valuable asset for forthcoming research endeavours focusing on the evolution, taxonomy, and genetic preservation of .

摘要

青蛙的线粒体基因组对于重建这些动物的系统发育关系和阐明分子进化至关重要。因此,在本研究中我们测定并分析了[青蛙名称未给出]的完整线粒体基因组序列。该序列全长19782个碱基对,总共包含37个基因,其中包括22个tRNA基因、13个蛋白质编码基因和2个rRNA基因,以及两个D环区域。线粒体基因组呈现出一种新的基因重排模式(tRNA--tRNA--CR1--CR2-tRNA-tRNA-tRNA)。线粒体基因组的核苷酸碱基组成包括32.51%的腺嘌呤(A)、31.32%的胸腺嘧啶(T)、21.95%的胞嘧啶(C)和14.21%的鸟嘌呤(G),表现出对AT含量的偏好(63.83%)。系统发育树是使用贝叶斯推断(BI)和最大似然(ML)方法构建的。研究结果表明[青蛙名称未给出]与[另一青蛙名称未给出]之间关系密切。[青蛙名称未给出]的完整线粒体基因组将成为未来聚焦于[青蛙名称未给出]进化、分类学和基因保存研究的宝贵资源。
