Suspension cultures of Habanero pepper (Capsicum chinense) were exposed to salicylic acid or methyl jasmonate to change secondary metabolism. Both treatments led to the accumulation of capsaicinoids and their late biosynthetic intermediate, vanillin. Both elicitors had a positive effect on the activities of phenylalanine ammonia lyase and coumarate O-methyltransferase, but none of them represented the main limiting step for capsaicinoid accumulation since vanillin contents were two orders of magnitude higher than those of capsaicinoids.
