A multi-disciplinary approach will be undertaken to study P. infestans, apply emerging genetic approaches, breed resistant germplasm, conduct field studies, and provide recommendations to the growers. An understanding of molecular interactions between host R gene products and pathogen effectors has provided valuable data that will allow us to identify or engineer novel R-genes that can be used in breeding programs. Characterization of the overwintering ability of novel P. infestans genotypes as mycelia on currently grown potato varieties and as oospores in field soil will provide needed biological information to production scientists for estimating epidemic risk for improved control recommendations. Cooperator will be responsible for studies on the overwintering capabilities of various P. infestans strains on potato tubers as well as assisting in field screening of germplasm.
