In this article we will discuss about how do plants protect and defend themselves from pathogens and diseases. Introduction to Pathogens: Once a pathogen has arrived in the vicinity of a potential host plant or, as may happen in the case of soil-borne pathogens, a plant root has arrived in the vicinity of a pathogen, subsequent events depend on the [...]
The following points highlight the four main modes of action suggested for biocontrol activity of antagonistic microorganisms. The modes are: 1. Antibiotic Production 2. Nutrient Competition between Antagonist and Pathogen 3. Direct Parasitism 4. Induction of the Host Defence Mechanism. Mode # 1. Antibiotic Production: It is appears to be a major mode of action for many antagonists. The antibiotic [...]
