Complete mitochondrial genome of the stone char Salvelinus kuznetzovi (Salmoniformes, Salmonidae)

Abstract

The complete mitochondrial genome was sequenced in two individuals of stone char Salvelinus kuznetzovi. The genome sequences are 16,654 bp in size, and the gene arrangement, composition and size are very similar to the salmonid fish genomes published previously. The low level of sequence divergence detected between the genome of S. kuznetzovi and the GenBank complete mitochondrial genomes of the white char S. albus (KT266870 and KT266871), the Northern Dolly Varden char S. malma (KJ746618) and the Arctic char S. alpinus (AF154851) may likely be due to recent divergence and/or historical hybridization and interspecific replacement of mtDNA.
