The complete mitochondrial genome of Discogobio laticeps (Cyprinidae: Labeoninae).

Discogobio laticeps is a small native economic fish species in southern China. Here, we reported the complete mitochondrial genome of D. laticeps for the first time. It was 16,596 bp in length and composed of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, a light strand origin of replication (O_L), and a control region (D-loop). The overall base composition was 32.3% of A, 15.2% of G, 26.4% of T, and 26.1% of C, with a slight A + T content of 58.7%. Maximum-likelihood phylogenetic tree suggested that D. laticeps had the closest evolutionary relationship with Discogobio longibarbatus. [ABSTRACT FROM AUTHOR]
