Complete mitochondrial genome of the freshwater gudgeon, Pseudopungtungia nigra (Cypriniformes, Gobioninae)

Abstract

The complete mitochondrial genome was sequenced from the freshwater fish, Pseudopungtungia nigra. The genome sequence was 16,605 bp in size, and the gene order and contents were identical with the cyprinid fish without any peculiar features. Of 13 protein-coding genes ( PGCs), 3 genes ( CO2, CO3 and Cytb) had an incomplete stop codon. The base composition of P. nigra showed anti-G bias (13.71% and 9.48%) on the second and third positions of PCGs.
