Key Findings
- Researchers at Wilfrid Laurier University found that warmer temperatures reduce plant defense by lowering salicylic acid (SA) levels
- The genes CBP60g and SARD1 are downregulated at higher temperatures, leading to decreased SA and weaker plant immunity
- The gene bHLH059, previously thought to regulate SA under stress, does not affect immune suppression in warmer conditions
