Mechanisms and balanced regulation of plant immunity
Nature Reviews Molecular Cell Biology, Published online: 27 August 2026; doi:10.1038/s41580-026-01009-4This Review discusses recent insights into the mechanisms of immune signalling in plants and their regulation to achieve effective defence against pathogens while preserving plant fitness. It also explores the interplay between the immune system and environmental stresses, and strategies for engineering optimal disease-resistant plants.
