RECENT ADVANCES IN POST-TRANSLATIONAL REGULATION OF PLANT DEFENSE RESPONSES BEYOND PHOSPHORYLATION

Abstract

During plant-microbe interactions, plant immune signaling relies significantly on post-translational modifications (PTMs) to induce rapid downstream changes. Organization at protein level is extensively complex and various forms of PTMs of transcript products provide a unique system in maintaining such an organization. With current proteomic research some detailed mechanisms of these PTMs have started to be uncovered. Pathogens also take PTMs as a virulence strategy to overturn host immunity through the activities of their effector proteins. In this review, we will address the importance of PTMs other than phosphorylation in plant defense response.
