Course content
|
- Introduction to the immune system of plants - basic components and specifics of responses to different types of pathogens. - Mechanisms of plant interactions with phytopathogens Host and non-host resistance, elicitors and membrane receptors as key molecules in pathogen recognition. - Signaling pathways of plant immunity - components of the early and late response of host plants to pathogens, the role of second messengers and protein kinase cascades, effector proteins and plant defense enzymes. - Plant hormones in the local and systemic response to phytopathogens - key hormones and regulators of plant immunity (salicylate, jasmonate, ethylene), biosynthesis, transport and mechanism of action. - Reactive oxygen forms in plant immunity (enzymatic and non-enzymatic production, catabolism, localization, non-enzymatic and enzymatic antioxidant systems, role in hypersensitive reaction. - The role of nitric oxide in plant immunity (function of NO under physiological and stress conditions, production and pathways of NO conversion, NO signaling pathways), post-translational modification of proteins by reactive forms of nitrogen. - Experimental methods of studying components of plant immunity - methods of determination and localization of reactive forms of oxygen and nitrogen, analysis of phenolic substances, total antioxidant capacity, lipid peroxidation.
