Abstract

Nine microsatellite loci were isolated and characterized from the clonal salt-marsh sedge Carex scabrifolia, and genetic diversities within four populations were analyzed. The number of alleles per locus ranged from 2 to 7, with an average of 4.7. The observed and expected heterozygosities ranged from 0.000 to 1.000 and 0.000 to 0.679, respectively. In two populations, almost all polymorphic loci showed a significant excess of heterozygotes due to their high clonal reproduction and low number of genotypes (genets) composing the populations. Thus, the number of identical genets varied greatly among populations and ranged from 1 to 28, irrespective of population size (i.e., population area and ramet number). When attempting to conserve and restore clonal plants such as C. scabrifolia, it is important to preserve sufficient genetic diversity within a population, which can be assessed using genetic markers such as the simple sequence repeat markers described here.
