The complete mitochondrial genome of Paraqianlabeo lineatus (Cyprinidae: Labeoninae)

Abstract

Paraqianlabeo lineatus is a small-sized fish which is endemic to Guizhou province, China. The complete mitochondrial genome of P. lineatus is 16,598 bp in total length, with 37 genes, including 13 PCGs, 22 tRNA genes, two rRNA genes (16S and 12S) and a non-coding region (D-loop). The positions and sequences of genes were consistent with congeners of Labeoninae. The nucleotide composition of the mitogenome was A (31.5%), T (26.7%), G (15.9%), C (25.8%) and was slightly A + T biased. Phylogenetic analysis conducted using Bayesian Inference method showed that P. lineatus clustered with Pseudogyrincheilus procheilus within the subfamily Labeoninae. The results may provide helpful data for further studies of the evolutionary history of Labeoninae.
