Organ‐specific terpenoid responses in Tanacetum vulgare are chemotype‐dependent

open access: yesPlant Biology, EarlyView.
Common tansy varieties defend differently: some boost root chemicals against soil pests, while others release stronger leaf scents against aphids. Abstract Specialized metabolites such as terpenoids are known to mediate plant defence mechanisms. However, how terpenoid diversity governs inducible chemistry across organs remains poorly understood.
