Microsatellite loci in the Gypsophyte Lepidium subulatum (Brassicaceae), and transferability to other Lepidieae.

ABSTRACT: Polymorphic microsatellite markers were developed for the Ibero-North African, strict gypsophyte Lepidium subulatum to unravel the effects of habitat fragmentation in levels of genetic diversity, genetic structure and gene flow among its populations. Using 454 pyrosequencing 12 microsatellite loci including di- and tri-nucleotide repeats were characterized in L. subulatum. They amplified a total of 80 alleles (2-12 alleles per locus) in a sample of 35 individuals of L. subulatum, showing relatively high levels of genetic diversity, H(O) = 0.645, H(E) = 0.627. Cross-species transferability of all 12 loci was successful for the Iberian endemics Lepidium cardamines, Lepidium stylatum, and the widespread, Lepidium graminifolium and one species each of two related genera, Cardaria draba and Cor
