The complete mitochondrial genome of Siberian sturgeon Acipenser baerii had been determined. The total length of the mitogenome was 16,763 bp and had 13 protein-coding, 22 tRNA, and 2 rRNA genes. Except for the eight tRNA and Nd6 genes, all other mitochondrial genes are encoded on the heavy strand. The overall base composition of the heavy strand is 30.3% A, 24.3% T, 29.1% C, 16.3% G, with an AT content of 54.6%. The DNA sequence of A. baerii shared 97.8, 97.6, 93.5, 91.6, 93.6, and 87.1% sequence homology with that of Acipenser sinensis, Acipenser gueldenstaedtii, Acipenser transmontanus, Acipenser dabryanus, Acipenser stellatus, and Polyodon spathula. Molecular data presented here provide a useful tool for evolutionary as well as population genetics studied. [ABSTRACT FROM AUTHOR]

The complete mitochondrial genome of Alosa sapidissima has been determined. The total length of the mitogenome was 16,697 bp and had a gene content (13 protein-coding, 22 tRNAs and 2 rRNAs. Except for the seven tRNA and Nd6 genes, all other mitochondrial genes are encoded on the heavy strand. The overall base composition of the heavy strand is 28.3% A, 24.8% T, 28.9% C, 17.9% G, with an AT content of 53.1%. The DNA sequence of Alosa. sapidissima shared 97.1, 93.9, 88.8 and 82.3% sequence identity with that of Alosa alosa, Alosa pseudoharengus. Molecular data here presented provide a useful toll for evolutionary as well as population genetic studied. [ABSTRACT FROM AUTHOR]

The complete mitochondrial genome of Japanese seabass Lateolabrax japonicus has been determined. The total length of the mitogenome was 16,601 bp and had the gene content of 13 protein-coding, 22 tRNA, and 2 rRNA genes. Except for the eight tRNA and Nd6 genes, all other mitochondrial genes are encoded on the heavy strand. The overall base compositions of the heavy strand are 27.27% A, 25.97% T, 29.35% C, and 17.41% G, with an AT content of 53.24%. The DNA sequence of L. japonicus shared 69.3%, 81%, 80.4%, and 79.7% sequence identity with that of Morone saxatilis, Histiopterus typus, Kyphosus cinerascens, and Siniperca scherzeri. Molecular data presented here provide a useful toll for evolutionary as well as population genetic studies. [ABSTRACT FROM AUTHOR]
