📌 Plant Pathology Series (Induced Defence – Structural & Biochemical): Part 3
This lecture explains how plants activate defence mechanisms when under pathogen attack, covering essential topics such as hypersensitivity response, systemic acquired resistance (SAR), and the roles of jasmonic acid, salicylic acid, systemins, defensins, and phytoalexins. These concepts are critical for understanding plant immunity and crafting high-scoring answers in Mains.
Key Takeaways:
1) Detailed explanation of hypersensitivity response and systemic acquired resistance (SAR)
2) Role of signaling molecules like jasmonic acid, salicylic acid, and systemins
3) Understanding antimicrobial peptides – defensins and phytoalexins
4) Structural and biochemical responses that strengthen plant immunity
5) Application of these mechanisms in Mains answer writing and PYQs
Strengthen your preparation with this insightful lecture!
