Simple sequence repeat (SSR) markers were developed for the flowering cherry Cerasus jamasakura (also known as Prunus jamasakura) using 31,995 expressed sequence tags (ESTs) from the NCBI database. Out of 96 of designed primer pairs, 63 showed clear PCR amplification and 13 of these revealed polymorphism in eight individuals sampled across the species' range. The number of alleles detected and expected heterozygosity ranged from 1 to 8 and 0.000 to 0.833, respectively, when these 13 loci were examined in 23 individuals from a single population. For all except one of the lcoi, polymorphism was also detected in at least four of six other taxa of flowering cherries examined. The results show that the developed EST-SSRs are highly transferable, and that these markers are likely to be useful in studies of the population genetics of flowering cherries.
