Prohibitin 3 forms complexes with isochorismate synthase 1 to regulate stress-induced salicylic acid production in Arabidopsis thaliana

Abstract

Salicylic acid (SA) is a major defense signal in plants. ln Arabidopsis thaliana, the main source of SA biosynthesis during abiotic shess (such as UV-C) or pathogen infections is a chloroplast-localized pathway. The enzyme isochorismate synthase I (ICSI)
