Abstract
Eleven polymorphic microsatellite loci were characterized for the endangered conifer Taxus yunnanensis. Eight loci were isolated through SSR-anchored PCR, one locus was developed by cross-species amplification tests, while the last two loci were obtained from cross-species microsatellite sequences available in GenBank. Variability of these markers was tested in 48 individuals collected from its main distribution range in Southwest China. The number of alleles per locus ranged from 2 to 9, and the observed and expected heterozygosity varied from 0.000 to 0.625 and from 0.062 to 0.853, respectively. Ten of these eleven loci were significantly deviated from Hardy–Weinberg expectation, except TS07 which showed a distinct heterozygote excess. The availability of these new polymorphic microsatellite markers will provide an ideal marker system for detailed population genetics studies in T. yunnanensis and potentially also for closely related species.
