Plant phosphopeptide-binding proteins as signaling mediators (original) (raw)

AI-generated Abstract

Plant signaling processes are fundamentally mediated by protein-protein interactions, with reversible phosphorylation playing a key role in regulating these interactions. This review focuses on the function of 14-3-3 and FHA domain proteins in plants as phosphopeptide-binding proteins, highlighting their roles in plant development, response to stress, and involvement in various signaling pathways. Evidence from proteomics, genetics, and physiological studies suggests that 14-3-3s are critical mediators of diverse signaling networks associated with hormones, light responses, and stress, marking them as essential components in the regulatory circuit of plant homeostasis.
