Research Description

Our long term goals are to understand the mechanisms that regulate intracellular and intercellular trafficking in plants, and common plant cell responses to pathogen attack. Most of our efforts focus on the biochemical functions and cellular interactions of the two movement proteins NSP and MP encoded by the bipartite geminiviruses, using these as models to investigate nuclear shuttling and the biogenesis of channels in plant cell walls. In collaboration with Alan Collmerís lab, we are also taking a functional genomics approach to investigate the roles of bacterial avirulence (avr) proteins in pathogenesis and in inducing host resistance responses in plants. The model geminiviruses we employ are SqLCV (squash leaf curl virus), which has a broad host range in cucurbits, and the closely-related CLCV (cabbage leaf curl virus), which has a broad host range in Brassica that includes Arabidopsis. Our functional genomics studies employ the model plant pathogenic bacterium Pseudomonas syringae pv. tomato DC3000.
