Study Notes
Module 3 Overview
- Module 3 discusses the mechanisms of how pathogens cause diseases in plants, disease development, and plant defense against pathogens.
- It also explores the mechanisms of variability in plant pathogens.
Genetic Variation in Plant Pathogens
- Conjugation is a sexual-life process involving the absorption and incorporation of DNA from other bacterial cells to effect variation.
- Mutation is a spontaneous heritable change of genetic material.
- A heterokaryon is a mycelium containing genetically different nuclei.
- Heterokaryosis is not a genetic variation process.
Disease Cycle
- The disease cycle involves an active stage.
