Exogenous chemicals can be used to stimulate induced resistance in susceptible plants against a broad range of pathogens.
The identification of molecular components related to induced resistance provides an understanding of the mechanisms
related to host resistance to pathogens. Environmentally friendly phosphite based fungicides are increasingly used in controlling
oomycete pathogens such as Phytophthora infestans, causing late blight of potatoes and other solanaceous crops. To contribute
to the understanding of Phi?s indirect mode of action, we used iTRAQ-based quantitative comparative proteomics to investigate
its effects on potato plants before and after infection with P. infestans. The majority of these Phi-responsive proteins revealed two
major molecular mechanisms related to defense and metabolism for energy generation. Defense functions include hypersensitive
response, reactive oxygen species pathway, salicylic acid-dependent pathway, and antimicrobial activities; energy generating
metabolisms include glycolysis, photosynthesis, and starch degradation. The outlook of the induced resistance in selected
cultivars brings new strategies to manage the disease in food production systems.
Gefu Wang-Pruski has completed her Ph.D. from University of Alberta 20 years ago. She is a university professor and researcher specializing in
potato production management. He has published more than 50 papers in reputed journals and several patents related to tuber quality and disease
controls. Wang-Pruski serves as editor and reviewer for numerous journals and advisors for national and international strategic innovation programs.
