Bacterial Pathogens of Plants

Bacterial diseases of plants cause substantial economic losses in agricultural industries worldwide. Management of these diseases depends on a limited number of often-ineffective tactics, including sanitation and cultural practices, resistant varieties, and bactericides. Plant disease resistance remains by far the best option. Studies of plant responses to Gram-negative plant pathogens have offered exciting new prospects for selecting or creating plants with broad disease resistance. It is not known to what extent findings from such model pathosystems are representative of the total repertoire of plant resistance responses to bacterial pathogens. Only recently has it become possible to examine plant responses to infection with Gram-positive coryneform bacteria. The long-term goal of this research is to develop plants with resistance to a broad spectrum of bacterial pathogens including Gram-positive coryneforms. The researchers use genomic sequences for pathogens and plants to identify genes required in pathogenesis and to develop better methods for diagnosis and management of plant diseases.
