Development of Microsatellites for the Genus Trillium.

The genus Trillium is widespread across both the United States and Asia, with 39 species found in the United States. It is characterized as a perennial herb that grows directly from rhizomes, often producing red, white or yellow flowers. Composed of more than 45 species, there is considerable diversity within this genus. Some species are rare such as Trillium pusillum and Trillium regulii, putting them at risk for extinction. As an understory plant, Trillium is essential in maintaining the structure and the function of the forests in which it inhabits. Due to a lack of resolution, the systematics of Trillium is uncertain and researchers are unsure of the relationships of the species within the genus. The purpose of this research project is to test current Trillium recurvatum microsatellites in order to determine if they will amplify across the genus, including in species such as Trillium tennesseense, Trillium ovatum, and Trillium undulatum. This project will test the transferability of the microsatellites between the species, giving us an insight as to the relationships of the species within this genus. Ideally, the use of these microsatellites will clarify these relationships and allow us to better construct a phylogenetic tree for the genus Trillium. Currently there are only two studies (one of which is in review) demonstrating the use of SSRs for this genus, indicating that there is much work to be done. Additionally, the data obtained with this project can also be extrapolated to conservation efforts across the genus Trillium.
