The environmental changes mainly caused by water pollution and human activities have dramatically threatened the survival of the small-scaled Wu's goby . In the present study, the complete mitogenome of was determined, which is 16,496 bp in length, containing 13 PCGs, two rRNA genes, 22 tRNA genes and a putative control region. The overall base composition is 28.6%, 29.0%, 26.7%, and 15.7% for A, T, C and G, respectively. The 13 PCGs encode 3,802 amino acids in total, twelve of which use the initiation codon ATG except , which uses GTG. In order to explore the systematic status of and further phylogenetic study of Gobiiformes, a maximum-likelihood tree was constructed based on the concatenated sequences of 12 PCGs. The result showed that , and clustered into a clade and then formed a sister-group with , suggesting the invalid former name of or .
主要由水污染和人类活动引起的环境变化极大地威胁了小鳞吴氏虾虎鱼的生存。在本研究中,测定了其完整的线粒体基因组,长度为16,496 bp,包含13个蛋白质编码基因(PCGs)、两个核糖体RNA基因、22个转运RNA基因和一个假定的控制区。总体碱基组成为A占28.6%、T占29.0%、C占26.7%、G占15.7%。13个PCGs共编码3802个氨基酸,其中12个使用起始密码子ATG,只有一个使用GTG。为了探究该物种的系统地位以及对虾虎鱼目进行进一步的系统发育研究,基于12个PCGs的串联序列构建了最大似然树。结果表明,该物种与其他某两个物种聚为一个分支,然后与另一个物种形成姐妹群,这表明该物种之前的名称或另一个相关物种的名称无效。 (注:原文中部分物种名缺失,翻译时按指代情况进行了表述)
