摘要: The complete mitochondrial genome sequence of Decapterus macrosoma has been obtained with overlapped polymerase chain reaction. The genome was 16,545 bp in length which contained 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 2 non-coding regions (the control region and the light strand replication origin). Gene organization was similar to that observed in most other vertebrates. With the exception of the ND6 and eight tRNA genes, all other genes were encoded on the heavy strand. The genomewas composed of 27.0% A, 30.4% C, 25.4% T and 17.2% G, showing an obvious anti-G bias commonly observed in teleosts. Two termination-associated sequence regions (TAS-1 and TAS-2), three central conserved sequence blocks (CSB-F, CSB-E and CSB-D), and three conserved sequence blocks (CSB-1, CSB-2 and CSB-3) were identified within the control region. The sequence data of D. macrosoma could provide useful information for the studies on molecular systematics and population genetics.
