Abstract: | The complete 1141 bp mitochondrial cytochrome b sequences were determined for lenok Brachymystax lenok , cherry salmon Oncorhynchus masou masou , Ishikawa's cherry salmon O. m. ishikawai , chum salmon O. keta , rainbow trout O. mykiss , and an albino mutant of rainbow trout. Common substitutions detected in these species were transitional mutations. There were no significant differences in the intraspecific variation of the cytochrome b genes. Interspecific divergences were greater than intraspecific variation. The level of variation ranged from 8·026–15·686%. The cherry salmon was closer to chum salmon than to rainbow trout, and the lenok was the most distantly related species. |
