1. Different Pathogens Causing diseases

2. How the pathogen attacks plant Mechanical forces Chemical weapons Enzymes Microbial toxics

3. Sir can i use this image instead of slide- 2 text info.

4. Defence Stratagies Pre existing Structural defenses  Wax and cuticle  Epidermal layer  Hydathodes  Lenticles Pre existing Biochemical defenses  Release of anti microbial compounds  Inhibitors present in the plant cells  Lack of essential factors

5. Induced Structural defence Lignification Suberization Abscission layers Tyloses Gum deposition Induced biochemical defence Toxic substance Role of phenolic compounds Role of phytoalexins Inactivation of enzymes
