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.

极端温度通过未知机制抑制水杨酸（SA）的生物合成，从而威胁植物免疫。Kim等人证明，SA途径和植物免疫的抑制可以通过两个主要免疫调节因子的最优表达来拯救，这有助于未来在气候变暖的情况下更好地保护植物。
