Complete mitochondrial genomes of two lenoks, Brachymystax lenok and Brachymystax lenok tsinlingensis.
The circular mitochondrial genomes of Brachymystax lenok and B. lenok tsinlingensis are 16,832 and 16,669 bp in length, respectively. The mitogenomes of two lenoks shared common features with those of other teleosts in terms of gene arrangement, base composition, and transfer RNA structures. The two genomes have an overall nucleotide sequence identity of 98.3%. Through the comparisons between the two lenoks, we found their gene arrangement, composition, and sizes are the same, and the A+T content is identical. As with other freshwater salmonids, a T-type mononucleotide microsatellite and various tandem repeats were identified in the control regions of the lenoks. The low pairwise distance (2.1%) inferred from 12 mitochondrial protein-coding genes on heavy strand showed close proximity of B. lenok and B. lenok tsinlingensis.
