Suspension cultures of Habanero pepper (Capsicum chinense Jacq.) 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.Additional key words: Habanero pepper, secondary metabolism, vanillin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
