Complete mitochondrial genome sequence and annotation of Rhinogobius lentiginis (Gobiiformes: Gobiidae: Gobionellinae)

We report the complete mitochondrial genome of Rhinogobius lentiginis, which was found to be a circular molecule of 16,633 bp in length and included 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, and a non-coding control region. The overall base composition was 28.44% A, 26.21% T, 16.33% G, and 29.02% C. Phylogenetic analyses using maximum-likelihood and Bayesian inference methods revealed a close genome relationship among R. lentiginis, R. niger, R. shennongensis and R. maculagenys. The complete mitogenome of R. lentiginis will provide a valuable resource for species classification and conservation.

本研究报道了斑吻虾虎鱼（Rhinogobius lentiginis）的完整线粒体基因组（mitochondrial genome）。该基因组为全长16633个碱基对（bp）的环状DNA分子，包含13个蛋白质编码基因（protein-coding genes, PCGs）、2个核糖体RNA（rRNA）基因、22个转运RNA（tRNA）基因以及1个非编码调控区。其整体碱基组成为：腺嘌呤（A）28.44%、胸腺嘧啶（T）26.21%、鸟嘌呤（G）16.33%、胞嘧啶（C）29.02%。通过最大似然法（maximum-likelihood）和贝叶斯推断（Bayesian inference）开展的系统发育分析显示，斑吻虾虎鱼与黑吻虾虎鱼（Rhinogobius niger）、神农吻虾虎鱼（Rhinogobius shennongensis）以及斑鳍吻虾虎鱼（Rhinogobius maculagenys）之间具有较近的基因组亲缘关系。斑吻虾虎鱼的完整线粒体基因组将为该物种的分类与保护提供宝贵的研究资源。
