Abstract:
The first complete mitochondrial genome of Ptychidio longibarbus is reported here. The circular genome is 16,604 bp long, containing 13 protein-coding genes, 22 tRNAs, two rRNAs, and a control region, with ∼239× coverage. All genes are located on the heavy strand except nad6 and eight tRNAs on the light strand. The mitogenome shows a typical A+T bias (57.72%). Phylogenetic analysis based on 12 concatenated PCGs places P. longibarbus in a well-supported clade with P. jordani and P. macrops, confirming its taxonomic position and providing new genomic resources for Labeoninae systematics and conservation.
