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

Abstract

The complete mitochondrial genome of the hybrid of Megalobrama amblycephala (♀) × Megalobrama skolkovii (♂) was characterized first in this study. The total length of the genome was identical to the female parent as 16 623 bp, and the overall base composition was 31.23% A, 24.69% T, 27.89% C, and 16.19% G, with a slight A + T bias. It contained 13 protein-coding genes (PCGs), 22 transfer RNA genes, 2 ribosomal RNA genes, and 2 main non-coding regions (the control region and the origin of the light-strand replication). This study discovered the 99.88% sequence identity between the hybrid and its female parent, which confirmed the maternal inheritance pattern followed by the mitochondrial genome of the hybrid. However, the sequence alignment of mitochondrial genomes between the hybrid and its female parent revealed a total of 20 variable sites in 10 genes or regions, especially 4 sense mutations in 2 PCGs (COX1 and ATPase6). The complete mitochondrial genome sequence of this hybrid bream may provide an important dataset for further study in mitochondrial inheritance mechanism.

“…The complete mitochondrial genome sequence of the hybrid Cyprinus capio Furong may provide an important dataset for further study in mitochondrial inheritance mechanism. In animal evolution, hybridization is a powerful approach of inducing genetic and epigenetic alterations, leading to increased diversity and speciation (Barton 2008;Guan et al 2015).
