Bacteria deactivate the protein synthesis of host cells to hamper immune reactions. This insight could aid in the development of more resistant plants.

Salicylic acid (SA), the active component of aspirin, is a crucial defense phytohormone that coordinates both local and systemic acquired resistance. For decades, SA biosynthesis was attributed to two pathways: (i) the isochorismate synthase pathway, which is dominant in arabidopsis (Arabidopsis thaliana) and other Brassicaceae, and (ii) the phenylalanine ammonia-lyase (PAL) pathway, common in most other plants. However, the PAL pathway remained biochemically incomplete due to the lack of a molecularly identified benzoic acid 2-hydroxylase. Recent findings fill this gap by identifying a conserved post-PAL route that converts trans-cinnamic acid to SA through benzoyl-coenzyme A (CoA) intermediates, spanning multiple subcellular compartments. This pathway explains pathogen-induced SA accumulation in non-Brassicaceae and establishes post-PAL metabolism as an ancestral, conserved mechanism underlying plant immunity.
