Message-ID: Next BSW meeting will be on Tuesday, February 7 at 7pm. Doors opening by 6:45pm. Speaker: Dr. Emily Bruns, Department of Biology, University of Maryland Topic: Evolution of Disease Resistance in Wild Plant Populations Here is an overview of her talk: Disease is a natural part of the ecology of wild plants. Strong disease pressure in nature can drive the evolution of plant resistance traits. However, the expression of resistance is not constant over a plant's life-history.? Instead, a frequently observed pattern in crops and wild plants is that seedlings and young plants are much more susceptible to disease than older, mature plants. But why? Getting infected as a seedling prior to reproduction is often far worse for an individual plant's fitness than getting infected as an adult after having a chance at flowering. In the talk I will explore several hypotheses concerning the evolution of age-specific disease resistance in wild carnations (Dianthus pavonius) and campions (Silene latifolia) to a sterilizing fungal pathogen (Microbotryum, the causal agent of 'anther-smut disease'). The talk will draw on observations of disease dynamics in wild populations in the alps, as well as greenhouse studies of susceptibility and tradeoffs.? Zoom link will be provided in a later email. ---------------------------------------------------------- News involving one of our past speakers, Nathan Harrington of the Ward 8 Conservancy.
