Too hot to defend: a tale of salicylic acid

Suraj, H.M.; SharathKumar, M.; Kan, J.A.L. van


Extreme temperatures threaten plant immunity by suppressing the salicylic acid (SA) biosynthesis via unknown mechanisms. Kim et al. demonstrated that suppression of the SA pathway and plant immunity can be rescued by optimised expression of two master immune regulator(s), advancing our prospects for better protecting plants in a warming climate.
