Polymorphic microsatellite loci in Lithophragma maximum (Saxifragaceae), an endemic plant of San Clemente Island

摘要

In this paper, we report the isolation of 11 polymorphic microsatellite loci from Lithophragma maximum (Saxifragaceae), a rare species restricted to San Clemente Island, California. We found moderate levels of allelic variation (mean N-A= 5.5) and high levels of expected heterozygosity (mean H-E= 0.531) across sampled individuals. However, eight loci showed a significant absence of heterozygous individuals, which we attribute to small population size and demographic history of the species.
