Reversible protein phosphorylation, a central signaling hub to regulate carbohydrate metabolic networks

Plants produce a range of carbohydrates to meet their growth and developmental needs. Protein reversible phosphorylation plays key roles in coordinating multiple metabolic pathways and integrating diverse internal and external cues. Understanding such regulatory metabolism will provide novel resources for breeding and crop management by modulating metabolic pathways for control of growth and stress response. In this review, we summarize the complex, multifaceted functions of protein phosphorylation and their connections to plant metabolism. We focus particularly on carbohydrate metabolic pathways that are controlled by key kinases and discuss how they are linked to downstream changes in physiology, important agronomic traits and crop quality.(c) 2023 Crop Science Society of China and Institute of Crop Science, CAAS.
