Premise of the study: Nuclear microsatellite primers were developed for the weedy herb Anacyclus clavatus to study the genetic structure of hybrid zones with closely related taxa in the western Mediterranean Basin, where different floral phenotypes are present. •
Methods and results: We obtained two microsatellite libraries using next-generation sequencing and Sanger sequencing of cloned restriction fragments. A total of 13 polymorphic and 11 monomorphic loci were identified in three Iberian populations of A. clavatus. The primers amplified di- and trinucleotide repeats with 1-8 alleles per locus. Most primers also amplified in A. homogamos, A. monanthos, A. radiatus, and A. valentinus. •
Conclusions: These results indicate the utility of these markers in A. clavatus for population genetic and hybridization studies as well as their applicability across the genus.
