Figure 1. Salicylic acid biosynthesis pathways. Isochorismate synthase (ICS) in isochorismate pathway. The 1–7 in shikimate pathway refers to 7 steps to produce the final product chorismate. Isochorismate synthase (ICS) and cinnamate 4-hydroxylase (C4H) enzymes in respective isochorismate and phenylpropanoid pathways are shown in red. The scheme was adapted after refs 61-64.
