We described the isolation and characterization of 27 new microsatellite loci from olive flounder, Paralichthys olivaceus . All loci were found to be polymorphic, and had between five and 22 alleles with observed heterozygosity ranging from 0.161 to 1.0 in 31 individuals examined. These micorsatellite makers are likely to be useful for studies of genome mapping, mating systems and population genetics in this species.
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. 2000 The Fisheries Society of the British Isles
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
