The complete mitochondrial genome of Dabry's sturgeon () was first determined in this study. The mitochondrial DNA is circular molecule (16,437 bp in length) with a typical vertebrate mitochondrial gene arrangement, including 13 protein-coding genes, 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and 1 non-coding control region (D-loop). All genes were encoded on the heavy strain except for ND6 and eight tRNA genes. The overall base composition of the heavy strain was A (30.2%), T (23.7%), C (29.7%), G (16.4%), and with an AT bias of 53.9%. Phylogenetic analysis based on the mitochondrial genomes of 10 related species using MEGA 5.1 indicated that and are the most closely related species.
本研究首次测定了达氏鲟（）的完整线粒体基因组。线粒体DNA是环状分子（长度为16437 bp），具有典型的脊椎动物线粒体基因排列，包括13个蛋白质编码基因、2个核糖体RNA（rRNA）基因、22个转运RNA（tRNA）基因和1个非编码控制区（D环）。除ND6和8个tRNA基因外，所有基因均在重链上编码。重链的总体碱基组成为A（30.2%）、T（23.7%）、C（29.7%）、G（16.4%），AT偏倚为53.9%。使用MEGA 5.1基于10个相关物种的线粒体基因组进行的系统发育分析表明，和是亲缘关系最密切的物种。
