Complete mitochondrial genome of Belligobio pengxianensis (Cypriniformes: Gobionidae)

Belligobio pengxianensis is a small fish endemic to the upper Yangtze River of China. In this study, the complete mitochondrial genome of B. pengxianensis is determined for the first time, and it should become a reference sequence to aid in species identification, biodiversity monitoring and conservation. The mitogenome has overall length of 16,610 bp and AT content of 55.23%, including 13 protein-coding genes, two ribosomal RNAs, 22 transfer RNAs, and one non-coding control region. The results of phylogenetic analyses show that B. pengxianensis is nested within the genus Hemibarbus.彭县似鳊（Belligobio pengxianensis）是一种小型鱼类，为中国长江上游特有物种。本研究首次测定了该物种的完整线粒体基因组（complete mitochondrial genome），该序列可作为参考序列，助力物种鉴定、生物多样性监测及保护工作。该线粒体基因组全长16610 bp，AT含量为55.23%，包含13个蛋白编码基因（protein-coding genes）、2个核糖体RNA（ribosomal RNAs）基因、22个转运RNA（transfer RNAs）基因，以及1个非编码调控区（non-coding control region）。系统发育分析（phylogenetic analyses）结果表明，彭县似鳊隶属于刺鮈属（Hemibarbus）。
