[Restriction analysis of mitochondrial DNA of the two forms of lenok Brachymystax lenok (Pall.) and taimen Hucho taimen (Pall.)].
Mitochondrial DNA analysis of the blunt-snouted and sharp-snouted lenoks of the sympatric zone (Amur basin) and blunt-snouted lenok of two allopartic populations (North-Eastern and Southern Primorye) as well as taimen was carried out with 12 restriction endonucleases. Nine mtDNA clones were resolved: in fours for each form of lenok and one for taimen. Estimation of the average percent of nucleotide differences of mtDNA (tau) obtained for one sample of sharp-snouted lenok was 0.51 + 0.17. For blunt-snouted lenok the similar value of tau (0.52 + 0.21) was reached by comparison of three geographically farthest populations (divided by approx. 1000 km) with each other. Two forms of lenok showed essential genetic differences--tau = 1.86 + 0.56. Estimation of tau between lenoks and taimen amounts to 3.25 + 0.89. Phylogeny of lenok and taimen and relationships between two forms of lenok on the East of the area are discussed.
