Genus-wide microsatellite primers for the Goldenrods (Solidago; Asteraceae)

Abstract

Premise of the study: Microsatellite primers were developed for studies of polyploid evolution, ecological genetics, conservation genetics, and species delimitation in the genus Solidago . • Methods and Results: Illumina sequencing of a shotgun library from S. gigantea identifi ed ca. 1900 putative single-copy loci. Fourteen loci were subsequently shown to be amplifi able, single-copy, and variable in a broad range of Solidago species. • Conclusions: The utility of these markers both across the genus and in herbarium specimens of a wide age range will facilitate numerous inter- and intraspecifi c studies in the ca. 120 Solidago species.
