Genome-wide molecular fingerprinting reveals local geographical genetic patterns in the North American angiosperm genus Triosteum (Caprifoliaceae).

ABSTRACT: Triosteum (Caprifoliaceae) is a genus of herbaceous perennial angiosperms composed of three Asian and three North American species. The range of two similar species, T. aurantiacum and T. perfoliatum, overlap in the state of Massachusetts, USA, where the latter species is considered locally endangered and protected by regulations. The population occurring in Barnstable Co. MA, USA was morphologically atypical and had intermediate characteristics between the two taxa. Genome-wide molecular fingerprinting was used to identify this population by comparison to nearby populations with typical morphology for each of the reference species T. aurantiacum and T. perfoliatum. A set of 220,518 high quality SNPs were used to calculate expected heterozygosity, FIS, nucleotide diversity, and FST, and to
