- Abstract
Summary: Plants have developed multilayered defense strategies to adapt and acclimate to the kaleidoscopic environmental changes that rapidly produce reactive oxygen species (ROS) and induce redox changes. Thiol‐based redox sensors containing the redox‐sensitive cysteine residues act as the central machinery in plant defense signaling. Here, we review recent research on thiol‐based redox sensors in plants, which perceive the changes in intracellular H2O2 levels and activate specific downstream defense signaling. The review mainly focuses on the molecular mechanism of how the thiol sensors recognize internal/external stresses and respond to them by demonstrating several instances, such as cold‐, drought‐, salinity‐, and pathogen‐resistant signaling pathways. Also, we introduce another novel complex system of thiol‐based redox sensors operating through the liquid–liquid phase separation.
