Mitochondrial genome of the Siberian sturgeon Acipenser baerii

Abstract

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.
