Abstract
Perccottus glenii is a species of freshwater sleeper native to the Russian Far East, north-eastern China, and the northern part of the Korean Penninsula with introduced populations in other regions of Eurasia. In this study, a new complete mitochondrial genome of Perccottus glenii was reported. The circular genome is 16,510 bp in length and consists of 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes, and 1 control region. Except the origin of the light strand replication (OL), an additional non-coding region was present between ND6 and tRNA-Glu in the Light strand. The overall nucleotide composition was 30.5% A, 29.2% T, 24.4% C and 15.9% G, with an A + T bias of 59.7%. The gene composition and the structural arrangement of the P. glenii complete mtDNA were identical to most of the other vertebrates. The molecular data here we presented could play a useful role to study the evolutionary relationships and population genetics of Odontobutidae fish.
