title: Characterization of 13 microsatellites for Lahontan cutthroat trout (Oncorhynchus clarki henshawi) and cross-amplification in six other salmonids.
abstract: Thirteen newly developed tri- and tetranucleotide repeat microsatellite markers were developed for Lahontan cutthroat trout (Oncorhynchus clarki henshawi), a threatened subspecies endemic to the Lahontan hydrographic basin in the western USA. These loci are highly polymorphic with five to 30 alleles per locus and observed heterozygosities ranging from 0.4 to 0.7. Cross-species amplification of these markers was most successful in the closely related rainbow trout, Oncorhynchus mykiss, with only three loci amplifying in brown trout, Salmo trutta. Nonoverlapping allelic distributions for many of these loci among the six salmonid species screened suggest these markers may be useful for hybrid determination.
