Microsatellite loci for studies of population differentiation and range expansion in Solidago sempervirens L. (Asteraceae)

Abstract

For studies of population differentiation and range expansion in the seaside goldenrod, Solidago sempervirens, we identified hypervariable molecular markers by screening genomic libraries enriched for microsatellite motifs. We designed primers that reliably amplified nine polymorphic loci. High polymorphism in a population from Delaware Bay, USA suggests that the loci will be useful in population studies. The success of cross-amplifications in 11 species of Asteraceae varied among loci and did not appear to reflect phylogenetic relationships within Solidago.
