摘要： The complete mitochondrial genome of the hybrid of O. stewartii (female) and S. younghusbandi (male) was sequenced and characterized in this study. The complete hybrid mitochondrial genome is 16,649 bp in length, including 2 rRNAs, 13 protein-coding genes, 22 tRNAs and 2 non-coding regions (OL and D-loop region). The results discovered that 99.89% sequence identity between the hybrid and its female parent, which confirmed the maternal inheritance pattern followed by the mitochondrial genome of the hybrid. The phylogenetic tree showed that the hybrid was relatively closer to O. stewartii. Our data would provide a valuable resource for further studies on mitochondrial inheritance mechanism of Schizothoracinae fishes and provide new insights for better conservation plans for fishery resources.
