Mitochondrial genome of the Western Pacific gizzard shad Nematalosa come (Clupeiformes: Clupeidae), with comparison to two Nematalosa species.

The complete mitochondrial genome sequence of Nematalosa come has been obtained with polymerase chain reaction, which contained 22 tRNA genes, 13 protein-coding genes, 2 rRNA genes and 2 non-coding regions (the control region and the light strand replication origin) with the total length of 16,644 bp. Gene organization was similar to that observed in most other vertebrates. Except for the ND6 genes and eight tRNA genes, all other mitochondrial genes were encoded on the heavy strand. The genome was composed of 26.1% A, 29.2% C, 24.8% T and 19.9% G, showing an obvious anti-G bias commonly observed in fishes. It shared 86.1% and 88.4% mitogenome sequence with Nematalosa nasus and Nematalosa japonica, respectively. The sequence date could provide useful information for the studies on molecular systematics and conservation genetics.
