A Worldwide Phylogenetic Analysis of Scutellaria.

The plant genus Scutellaria (family Lamiaceae) is comprised of approximately 350 cosmopolitan species. Twenty-four species are found in the southeastern US. The genus has been used medicinally on multiple continents, predominantly for its anxiolytic,anti-inflammatory and analgesic properties. Recently, certain species in the genus have been investigated for their ability to inhibit cancer cell growth. Despite the vast interest in the group, a molecular phylogeny has never been performed on the genus as a whole. My project involves a preliminary phylogenetic analysis of Scutellaria with representatives from every continent except Antarctica. Specimens from the field, herbaria (MO, NY, VSC), and the lab of Richard Olmstead (University of Washington) will be extracted for a total of 28 species including one outgroup, Holmskioldia. Gene regions sequenced will include matK, rps16, and trnL-F. The resulting phylogeny will provide a preliminary scaffolding upon which a more targeted approach to medicinal screening within the genus can be based.
