The complete mtDNA genome of suspected natural Bagridae hybridization (Pelteobagrus olimcorporis sp.nov): genome characterization and phylogenetic analysis

The complete mitochondrial genome sequence of the suspected new species (Pelteobagrus olimcorporis sp.nov) was first determined by a PCR-based sequencing method in this study. The complete mtDNA genome of this suspected new species is 16,533 bp in length and consists of 13 protein-coding genes, 22 transfer RNA genes (tRNA), two ribosomal RNA genes (rRNA) and a non-coding control region (D-loop). Compared with the 13 proteins genome of the Bagridae and Cyprinidae, results showed that this suspected new species was clustered together and from a sister group with fishes of Bagridae. Blasting the special region on NCBI, we found 99% of the sequence was the same with Pseudolaubuca sinensis. It indicated that P. olimcorporis sp.nov is a hybrid and the mitochondrial genomes of the father may permeate to the hybrid.
