4th Edition Of Plant Science and Molecular Biology World Conference 2027

Plant immunity and disease resistance are central to food security, and this session at PMBWC 2027 focuses on the molecular basis of plant defence and the discovery of resistance genes. Plants protect themselves from pathogens through an immune system based on receptors that recognise invading organisms and trigger defence responses. When a crop lacks effective resistance, diseases such as Fusarium wilt, rusts and blights can cause serious yield losses. Plant pathogens are constantly changing, and resistance that works well today may fail in a few years as new pathogen strains appear. A better understanding of how plants detect and respond to pathogens helps researchers find stronger resistance genes and combine them in ways that are harder for pathogens to overcome. This knowledge also supports the development of crops that need fewer chemical pesticides.

This session covers the molecular basis of plant immunity, including pattern-triggered and effector-triggered immunity, NLR receptors and systemic acquired resistance. It also includes the identification, cloning and deployment of resistance genes and strategies for long-lasting disease resistance in crops.
