Complete mitochondrial genomes of endemic charr of the genus Salvelinus from Lake Nachikinskoe (Kamchatka, Russia)

The complete mitochondrial genomes were sequenced from three individuals of the endemic charr Salvelinus sp. 4 [ from Lake Nachikinskoe (Kamchatka, Russia). The complete mitochondrial genomes were 16,654 bp in size; the genome organization and GC content (45.6%) was consistent with charr mitochondrial genomes published previously. The low level of sequence divergence detected between the Salvelinus sp. 4 and the GenBank Salvelinus taranetzi genomes indicated recent divergence and their origin from a common ancestor. Our results could play an essential role in resolving the conflict over current taxonomic status of endemic charr in genus Salvelinus.

Automated summary

The complete mitochondrial genomes of three individuals of the endemic charr Salvelinus sp. 4 from Lake Nachikinskoe (Kamchatka, Russia) were sequenced, and the low level of sequence divergence between Salvelinus sp. 4 and GenBank Salvelinus taranetzi genomes suggests recent divergence and a common ancestor. These findings have significant implications for resolving the taxonomic status of endemic charr in the genus Salvelinus.
