Research Interests

• Phytobacteriology and molecular plant-microbe interactions
• Molecular basis of pathogenicity of bacterial plant pathogens, including mechanisms of water-soaking (Wts) and wilting and regulation of pathogenicity genes
• Extracellular polysaccharides as pathogencity factors using the corn pathogen, Pantoea stewartii as a model system; Hrp type-III protein secretion system, Wts effector proteins and cell death and/or suppression of host defenses; nature of the secreted Wts proteins and the regulation of the hrp/wts genes
