Abstract Detail



Plant Secondary Chemistry: from Biochemistry to Applications

Daayf, Fouad [1].

Biochemical warfare at the plant-pathogen interface: examples and implications.

Both cultural and chemical practices aimed at reducing the impact of plant diseases on economic crops have limitations. As a result, billions of dollars are lost to plant diseases caused by microbial pathogens every year, and in chemical disease management programs. Strategic integration of cultural, chemical, and biotechnological management measures is considered a must in mitigating the negative impact of plant diseases either through prevention or proper control of such diseases. However, building a strategic management plan for any plant disease requires specific knowledge about the host, the pathogen, their interaction mechanisms, and how these are affected by their environment. Host-pathogen interactions follow processes that often are, or respond to, chemical and biochemical reactions. This talk will present host-pathogen interaction examples that will illustrate the ability of host plants to produce and deploy biomolecules in response to invading pathogens, and how the latter react through counter-defense strategies that would help overcome biochemical plant defenses. Insights will be presented on how such knowledge can be used in addressing disease problems in the field.
