碩士 === 國立中央大學 === 生命科學系 === 106 === Microhyla fissipes was first recognized in Tainan, Taiwan (type locality), however it is not highly accepted. Herein, author used the sample from Yi-Lan, Taiwan as a representative of Taiwan samples and obtained the complete mitochondrial genome sequence (accession number: MF673131) in order to study the phylogeny of Microhyla fissipes and its relevants, especially in the comparison with the China sample (NC_009422). Although the genome of our sample (16,729 base pairs) contains genes and gene order almost identical to other amphibians’, some variations have been accumulated between Taiwan and China samples. Interestingly, we noticed that ND5 and ND6 genes evolved very differently from other genes. Also there were strongly codon usage bias with high thymine frequency at the second codon and very low guanine frequency at the third codon.
