Development of microsatellite markers in Robinsonia (Asteraceae) an endemic genus of the Juan Fernández Archipelago, Chile.

Ten microsatellite markers were developed for Robinsonia (Asteraceae), a genus endemic to the Juan Fernández Archipelago, Chile. Polymorphisms of these markers were tested using one population each of R. evenia, R. gayana, and R. gracilis. The number of alleles for these markers ranged from 2 to 17 per locus, and expected heterozygosity ranged from 0 to 0.847 by population. A significant deviation from Hardy-Weinberg equilibrium was observed in zero to two markers in each population, and no significant linkage disequilibrium between markers was detected. The markers reported here would be useful for evolutionary studies and conservation strategies in Robinsonia.
