The complete mitochondrial genome of the hybrid of Megalobrama amblycephala (♀) × Parabramis pekinesis (♂)

Abstract

The complete mitochondrial genome sequence of the hybrid of blunt snout bream (Megalobrama amblycephala) (♀) × white Amur bream (Parabramis pekinesis) (♂) (M × P) was determined using the PCR-based method for the first time. The total length of the mitogenome was 16,623 bp in accordance with blunt snout bream. It contained 37 genes (13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes) and 2 main non-coding regions (the control region and the origin of the light strand replication). Compared with the complete mitochondrial genome of the parents, results showed the hybrid bream was consistent with a maternal inheritance; however, we also found a termination codon mutation in Cytb and a double-based site in 16S rRNA which was species-specific for the male parent P. pekinesis. The complete mitochondrial genome sequence of the M × P bream provided an important data set for further study in mitochondrial inheritance mechanism.
