ABSTRACT
We report the first 16 polymorphic nuclear microsatellite markers developed for Frangula alnus (Rhamnaceae). Markers were tested on all three subspecies as well as on three local populations, including analyses of both leaf and seed endocarps. A total of 87 alleles were found (mean number of alleles per locus was 5.44) for 72 individuals genotyped. Observed and expected heterozygosities ranged from 0.097 to 0.792 and from 0.093 to 0.794, respectively. The levels of polymorphism and exclusionary power of the developed markers render them applicable for parentage analyses and measurements of seed dispersal through direct comparison of endocarps and adult tree genotypes.
ABSTRACT
Twelve polymorphic microsatellite loci were developed for Rhamnus alaternus using an enriched-library approach. We detected 69 alleles in 49 individuals genotyped (mean number of alleles per locus was 4.79) in two different populations. The values of observed and expected heterozygosities ranged from 0.045 to 0.963 and 0.089 to 0.873 respectively. Levels of polymorphism and the exclusionary power of the developed markers render them readily applicable for studies of contemporary pollen and seed gene flow through parentage analyses.
