Deciphering phenylalanine-derived salicylic acid biosynthesis in plants.

ABSTRACT: Salicylic acid (SA) is a ubiquitous plant hormone with a long history in human civilization^1,2. Because of the central role of SA in orchestrating plant pathogen defence, understanding SA biosynthesis is fundamental to plant immunity research and crop improvement. Isochorismate-derived SA biosynthesis has been well defined in Arabidopsis. However, increasing evidence suggests a crucial function for phenylalanine-derived SA biosynthesis in many other plant species¹. Here we reveal the phenylalanine-derived SA biosynthetic pathway in rice by identifying three dedicated enzymes - peroxisomal benzoyl-CoA:benzyl alcohol benzoyltransferase (BEBT), the endoplasmic reticulum-associated cytochrome P450 enzyme benzylbenzoate hydroxylase (BBH), and cytosolic benzylsalicylate est
