Mitogenomic Characterization of <i>Microhyla fissipes</i> and Its Implications for Phylogenetic Analysis in Microhylidae.

ABSTRACT: The microhylid frog Microhyla fissipes is a protected terrestrial wildlife species in China, recognized for its ecological, economic, and scientific value. However, its mitochondrial genome remains poorly characterized. To address this gap, we sequenced and annotated the complete mitogenome of M. fissipes to elucidate its structural organization and phylogenetic placement within Microhylidae. The assembled mitogenome is 16,723 bp in length and contains 37 genes, including 13 protein-coding genes, 2 rRNAs, and 22 tRNAs, along with one control region and the origin of heavy-strand replication. We also identified eight overlapping regions and eleven intergenic spacers. The overall base composition showed an A + T bias (59.91%) with negative AT-skew (-0.04) and GC-skew (-0.27). A
