Masters Theses
Pityopsis graminifolia var. latifolia (Michx.) Small var. latifolia (Fern.) or narrowleaf silkgrass is an herbaceous perennial native to the southeastern United States and northern Central America. Pityopsis ruthii (Small) Small is an endangered plant endemic to the Hiwassee and Ocoee Rivers in Polk County, Tennessee. Little is known about the genetic diversity and population structure of both Pityopsis species as well as the phylogenic relationships between the species. In this study, 16 microsatellite loci were used to assess genetic diversity and population structure of 261 individuals of P. ruthii (n=167) and P. graminifolia var. latifolia (n=76). Pityopsis ruthii is …
