Complete mitochondrial genome of the Greenspot goby Acentrogobius chlorostigmatoides (Perciformes, Gobioidei): repetitive sequences in the control region.

The Greenspot goby, Acentrogobius chlorostigmatoides (Gobiidae, Gobiinae), is a small-sized (80-110 mm), warm water, and benthonic fish, which inhabits the nearshore area and riverine estuaries of freshwater and brackish, mainly distributed in the coastal of Indonesia to China. In this study, the complete mitochondrial genome of A. chlorostigmatoides was firstly determined. The genome is 17,098 bp in length and consists of 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes, and 2 main noncoding regions (the control region and the origin of the light-strand replication). The overall base composition of A. chlorostigmatoides is 26.0% for T, 28.7% for C, 29.3% for A, and 15.9% for G, with a slight A+T bias of 55.3%. Within the control region, the termination-associated sequence, central, and conserved sequence block domains were found. Moreover, a 650-bp tandem repeat, which started from the 785-bp site of the control region, was identified.
