Isolation and characterization of microsatellite loci in Fimbristylis sericea (Cyperaceae)(1.).

Premise of the study: We developed microsatellite markers for Fimbristylis sericea, a coastal herb found in sand dunes in Asia and Australia. Methods and Results: Twelve microsatellite loci were isolated, and the genetic variability within and among local populations was characterized. The number of alleles per locus was two to five with a mean of 3.5, total expected heterozygosity per locus was 0.069-0.645 with a mean of 0.336, and average expected heterozygosity within a population per locus was 0.051-0.230. Most of the loci deviated significantly from Hardy-Weinberg equilibrium. Conclusions: All 12 microsatellite loci were polymorphic within and among populations. These loci could be useful genetic markers for population genetic studies of F. sericea populations.
