The complete mitochondrial genome of the hybrid fish Salvelinus fontinalis (♀) × Salvelinus malma sp. (♂)

摘要

The complete mitochondrial genome sequence of the hybrid fish Salvelinus fontinalis (♀) × Salvelinus malma sp. (♂) was sequenced. It was 16,623-nucleotide in length and consisted of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 2 non-coding regions (L-strand replication origin and control region), showing conserved gene arrangement with most vertebrates. The phylogenetic tree showed the hybrid salmon to be one of the Salvelinus and the relationships of S. fontinalis were closer. The complete mitochondrial genome sequence of S. fontinalis (♀) × S. malma sp. (♂) provided an important dataset for a better understanding of the mitogenomic diversities and evolution in salmon fish as well as novel genetic markers for studying population genetics and species identification.
