Foundations of Plant Biology
2-3 weeksStudy basic plant anatomy, cell biology, and physiology including photosynthesis, transpiration, and plant hormone signaling. Understand plant tissue types (epidermis, vascular, ground tissue) and how they relate to disease susceptibility and defense.

Introduction to Plant Pathogens
2-3 weeksLearn about the major groups of plant pathogens: fungi, oomycetes, bacteria, viruses, viroids, nematodes, and phytoplasmas. Understand their basic biology, classification, and modes of infection. Study Koch's Postulates and modern molecular diagnostic methods.
Disease Development and the Disease Cycle
2-3 weeksStudy the Disease Triangle and the sequential stages of disease development: inoculation, penetration, infection, colonization, reproduction, and dissemination. Learn about primary and secondary inoculum and how environmental factors influence each stage.
Plant Defense Mechanisms and Immunity
3-4 weeksExplore structural and biochemical defenses, PAMP-triggered immunity (PTI), effector-triggered immunity (ETI), the hypersensitive response, systemic acquired resistance (SAR), and induced systemic resistance (ISR). Understand the zigzag model of plant immunity.
Epidemiology and Disease Ecology
2-3 weeksLearn how diseases spread through plant populations over time and space. Study disease progress curves, monocyclic vs. polycyclic epidemics, spatial analysis, forecasting models, and the influence of climate and cropping systems on disease epidemics.
Disease Management Strategies
3-4 weeksStudy cultural controls (crop rotation, sanitation, resistant varieties), chemical controls (fungicides, bactericides, nematicides and resistance management), biological control agents, and integrated pest management (IPM) principles.
Molecular Plant-Microbe Interactions
3-4 weeksDive into the molecular basis of pathogenesis: pathogen effector biology, type III secretion systems, gene-for-gene interactions, R gene structure and function, signal transduction in plant immunity, and the arms race between plants and pathogens.
Advanced Topics and Current Frontiers
3-5 weeksExplore cutting-edge research areas: genomics and metagenomics in pathogen diagnostics, CRISPR-based disease resistance engineering, climate change impacts on plant disease, microbiome-mediated disease suppression, remote sensing for disease detection, and global food security challenges.
