| Description: |
SUMMARY Plant glycolysis and the tricarboxylic acid (TCA) cycle are key pathways of central carbon metabolism. They facilitate energy transformation, provide redox balance, and supply the building blocks for biosynthetic processes that underpin plant survival, growth, and productivity. Yet, rather than acting as static pathways, the fluxes that are mediated by the enzymes involved form a branched network. Flux modes can change flexibly to match cellular demands and environmental fluctuations. Several of the enzymes involved in glycolysis and the TCA cycle have been identified as targets of posttranslational modifications (PTMs). PTMs can act as regulators to facilitate changes in flux by rapidly and reversibly altering enzyme organization and function. Consequently, PTMs enable plants to rapidly adjust their metabolic flux landscape, match energy and precursor provision with the changeable needs, and enhance overall metabolic flexibility. Here, we review the impact of different PTMs on glycolytic and TCA cycle enzymes, focusing on modifications that induce functional changes rather than the mere occurrence of PTMs at specific sites. By synthesizing recent findings, we provide a foundation for a system‐level understanding of how PTMs choreograph the remarkable flexibility of plant central carbon metabolism. |
