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.

The Structure of the Chemotype Determining Locus in Cannabis sativa

open access: yesPlant Direct, Volume 10, Issue 5, May 2026.
ABSTRACT The chemical phenotype (chemotype) of Cannabis sativa is defined by the ratio of cannabidiolic acid (CBDA) to Δ9‐tetrahydrocannabinolic acid (THCA). Although the Mendelian segregation of these traits suggests a single‐locus biallelic system, recent sequencing and phylogenetic evidence indicate they are encoded by two distinct, tightly linked ...
