The Complete Mitochondrial Genome of Nearly Threatened Kwang-Yang Asian Frog <i>Nanorana quadranus</i> (Anura: Dicroglossidae) and Its Phylogenetic Analyses.

ABSTRACT: Nanorana quadranus (Liu, Hu & Yang, 1960) is a high-altitude amphibian species native to the Qinghai-Tibet Plateau. It plays a vital role in alpine wetland ecosystems and is listed as near threatened (NT) in the IUCN Red List. Here, we present the first complete mitogenome of N. quadranus using the Illumina NovaSeq 6000 sequencing platform. The total length of the mitogenome is 20,173 bp (Accession No. PV546862). It encompasses 13 protein-coding genes (PCGs), 21 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), and one control region. Phylogenetic analysis revealed that N. quadranus forms a clade with N. taihangnica, supporting its taxonomic placement within the Dicroglossidae family. This study provides foundational genetic data for further research on the evolu
