Allelopathy, Evolution and Plasticity in Garlic Mustard

Abstract: Invasive plants offer excellent opportunities to study evolutionary processes because they are released from selective pressures in the native range and experience novel selective pressures in the invasive range. In order for a species to become invasive, they must respond to these changes, either through evolution or through plasticity. The goal of my research is to identify traits that are adaptive and determine whether evolution or plasticity for these traits is facilitating the invasion process. Garlic Mustard (Alliaria petiolata) is a member of the Brassicaceae family, which was introduced into North America in the 19th century and has since spread across much of the continent. I used genotypes collected throughout the invasive range of A. petiolata and subjected these genotypes to relevant selective pressures to determine which traits may be adaptive, under selection, or exhibiting adaptive plasticity. The main focus of my research surrounds the evolution of glucosinolate and flavonoid compounds in A. petiolata, particularly regarding their role in intra- and interspecific competition.
