Research Interests

Fungal endophytes of plants may play important roles in adapting hosts to their environments and defending them from biotic and abiotic stresses. In my lab we are exploring diversity of endophytes and the various impacts that they have on host plants. We are working to develop use of the clavicipitalean endophytes as a model system for understanding the evolution and dynamics of defensive mutualisms. In this respect we are interested in how endophytes in this family have evolved and how they have spread to various continents. Further, we are interested in how evolution has progressed in the Clavicipitaceae; and how the clavicipitalean-plant defensive mutualism itself evolved. The host-symbiont interface in the biotrophic Clavicipitaceae is another area of interest. In particular, we are interested in understanding how the clavicipitalean biotrophs induce plant hosts to release nutrients. Unlike most biotrophs, members of the Clavicipitaceae do not possess haustoria or other specialized structures for nutrient absorption; and they do not penetrate or otherwise degrade host cells. Thus the mechanism by which nutrients are extracted from hosts is a mystery. We are increasingly also interested in understanding how the abiotic environment impacts the parasitism-mutualism continuum. Some recent research in the lab has demonstrated that abiotic factors like light intensity may alter where a particular association falls in the parasitism-mutualism continuum. It is entirely possible that many abiotic factors influence the effect that endophytes have on their hosts. This phenomenon could important in determining the distributions of plant hosts.
