Increasing the resilience of plant immunity to a warming climate

J. H. Kim, C. D. Castroverde, et al.

This groundbreaking research conducted by Jong Hum Kim, Christian Denv. Castroverde, and their team unveils how climate change's extreme temperatures hinder salicylic acid production in plants, ultimately weakening their immune defenses. The study highlights the potential of optimizing *CBP60g* expression to enhance plant resilience against climate change.

Abstract

Climate change-induced extreme weather suppresses salicylic acid (SA) production in plants, compromising immunity. This study reveals that high temperatures (28°C) reduce the formation of GUANYLATE BINDING PROTEIN-LIKE 3 (GBPL3) defense-activated biomolecular condensates (GDACs), impairing recruitment of GBPL3 and SA-associated mediators to promoters of *CBP60g* and *SARD1*, master immune transcription factors. Optimizing *CBP60g* expression broadened metabolic responses to elevated temperatures, suggesting a strategy for enhancing climate-resilient plant immunity.
