Identification and characterization of microsatellite loci in Betula maximowicziana Regel

The sequences of eight primer pairs of microsatellite loci screened from a genomic library of Betula maximowicziana are reported in this paper. Seven loci showed polymorphism in 44 individuals of the Mitomi population in the central area of Japan and the observed and expected heterozygosities ranged from 0.045 to 0.659 (mean = 0.412) and from 0.044 to 0.642 (mean = 0.397), respectively. Although the one remaining locus is not polymorphic there, it showed variation in other populations. Thus, these eight microsatellite markers might be useful tools for studying the population and ecological genetics of B. maximowicziana.
