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

Plant 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.

Effect of Origanum chemotypes on broiler intestinal bacteria

Poultry Science, 2014
Essential oils have been proposed as alternatives to antibiotic use in food animal production. This study evaluated 3 chemotypes of the Origanum genus, containing varying amounts of secondary metabolites carvacrol, thymol, and sabinene, in the broiler chicken diet. Aerial parts of Origanum vulgare L. (OL), O. vulgare L. ssp.

Comparing genotype and chemotype of Fusarium graminearum from cereals in Ontario, Canada

, 2019
Fusarium graminearum is responsible for production of the mycotoxin deoxynivalenol (DON) on maize and wheat in Ontario, Canada. It has been understood since the early 1980s that in most parts of Canada, the predominant chemotype of F.

Essential oil composition from twelve varieties of basil (Ocimum spp) grown in Colombia

Journal of the Brazilian Chemical Society, 2003
Essential oil compositions of aerial parts from twelve basil cultivars (Ocimum spp) were analysed by gas chromatography-mass spectrometry (GC-MS). Ten of them were characterized by the presence of a high percentage of methyl cinnamate (35-80%), which ...

Cloning and functional characterisation of a cis -muuroladiene synthase from black peppermint (Mentha x piperita) and direct evidence for a chemotype unable to synthesise farnesene

, 2006
Using oligonucleotide primers designed to the known gene sequence of an (E)-β-farnesene (EβF) synthase, two cDNA sequences (MxpSS1 and MxpSS2) were cloned from a black peppermint (Mentha × piperita) plant.
