Insights Into the Role of Lysine Acetylation of Non-Histone Proteins in Plant Immunity.

Lysine acetylation of non-histone proteins plays a crucial role in plant immunity, with over 1000 acetylated proteins identified during pathogen interactions.

• Why it matters: Understanding posttranslational modifications like lysine acetylation is vital because they regulate immune responses beyond gene expression, yet their mechanisms remain poorly understood.
• What they did: The review analyzes acetyl-lysine proteome studies involving plant interactions with fungi, bacteria, and viruses, focusing on the roles of plant and pathogen-derived KATs and KDACs.
• The result: Findings reveal that bacterial effectors mimic KAT activity to modify plant proteins, highlighting new targets for enhancing disease resistance and advancing molecular strategies in plant immunity research.
