The Complete Mitochondrial Genome of <i>Acrossocheilus spinifer</i> (Osteichthyes: Cyprinidae) and Its Phylogenetic Analysis
In this study, we sequenced and characterized the complete mitochondrial genome of <i>Acorssocheilus spinifer</i>, an endemic stream-dwelling cyprinid species from South China first described in 2006. The mitogenome is 16,591 bp in length and contains the standard set of 37 genes (13 pro...

| description | In this study, we sequenced and characterized the complete mitochondrial genome of <i>Acorssocheilus spinifer</i>, an endemic stream-dwelling cyprinid species from South China first described in 2006. The mitogenome is 16,591 bp in length and contains the standard set of 37 genes (13 protein-coding genes, 22 tRNA genes, 2 rRNA genes) plus a control region. The genome exhibits typical cyprinid characteristics, with most genes encoded on the H-strand and a nucleotide composition biased toward A + T (55.9%). All tRNA genes display the typical cloverleaf secondary structure, except for tRNA<sup>Ser</sup> (GCU), which lacks the dihydrouridine (DHU) arm. Phylogenetic analysis using complete mitogenomes from 14 <i>Acrossocheilus</i> species revealed that 12 species form a monophyletic assemblage with three distinct clades. Within this framework, <i>A. spinifer</i> clusters closely with <i>A. beijiangensis</i>, supporting previous morphological observations. Our findings provide valuable genetic data for further taxonomic refinement and conservation efforts for Chinese barred species of <i>Cyprinidae</i>. |
