The CAT(2) Comes Back.
Genetic and biochemical evidence supporting CATALASE2 as a salicylic acid (SA) receptor has finally emerged. In this issue of Cell Host & Microbe, Yuan et al. (2017) show that SA binds to CATALASE2 to inhibit auxin and jasmonic acid biosynthetic enzymes as a means to strengthen plant immunity against biotrophic pathogens.
