The complete mitochondrial genome of the hybrid of Megalobrama skolkovii (♀) × Megalobrama amblycephala (♂).
In this study, we sequenced the complete mitochondrial genome of the hybrid of Megalobrama skolkovii (♀) × Megalobrama amblycephala (♂) for the first time. The complete mitochondrial genome of the hybrid bream was found to be 16 621 bp in size with a mostly conserved structural organization when compared with that of other Megalobrama species. It contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and two main non-coding regions (the control region and the origin of the light strand replication). Sequence alignment of mitochondrial genomes between the hybrid and its female parent showed that a total of 38 mutation sites in 13 genes or regions, in particular, three sense mutations in three protein-coding genes (COX1, ND4L, and ND5) with 27 mutation sites in nine protein-coding genes. This mitogenome sequence data would contribute to a better understanding of genetic mechanisms of mitochondrial DNA and phylogenetic analysis in hybrids.
