Complete mitochondrial genome of the urohaze-goby Glossogobius olivaceus (Perciformes, Gobiidae) and structure comparison of light strand replication origin in Gobioidei

Abstract

The genome of Glossogobius olivaceus (G. olivaceus) was 16,568 bp in length with a standard set of 13 protein-coding genes, 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs) and 2 non-coding region (the control region and origin of the light strand replication). The conserved motif 5′-GCCGG-3′ was determined in the origin of light strand replication of G. olivaceus. The G. olivaceus mitogenome base composition was: T 25.65%, C 29.82% A 27.17% and G 17.36%, with a slight A + T bias of 52.82%, which was similar to most of the vertebrate mitogenomes. The mitochondrial genome of G. olivaceus had common features regarding gene arrangement and tRNA structures compared with those of other bony fishes.
