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.

Evaluation of Enzyme Inhibition and Kinetic Profiles of Origanum Essential Oils on Metabolic and Central Nervous System Targets

Natural Sciences, Volume 6, Issue 3, July 2026.
The essential oils of three Origanum species were chemically characterized and evaluated for their antioxidant and enzyme inhibitory activities. The different compositions confer selective bioactivities: O. vulgare exhibits good antioxidant and α‐glucosidase inhibitory activity, O. majorana shows promising tyrosinase inhibition, and O.

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.

Pharmacologic MRI Brain Imaging Studies of Serotonin 5‐HT1 Receptor Agonists in Awake Mice

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Serotonin (5‐hydroxytryptamine, 5‐HT) type‐1 G protein‐coupled receptors are expressed throughout the central nervous system. 5‐HT1AR activation is the putative mechanism of approved drugs for generalized anxiety disorder and major depressive disorder and is being studied in the treatment of autism and neurological disorders.

Host tree preference and performance of the Eurasian spruce bark beetle (Ips typographus) on Scots pine

Pest Management Science, Volume 82, Issue 6, Page 5850-5860, June 2026.
Ips typographus showed lower reproductive output in an occasional host (Pinus sylvestris) under laboratory conditions, and did not prefer its main host (Picea abies) over P. sylvestris in two‐choice bioassays. Abstract BACKGROUND The Eurasian spruce bark beetle, Ips typographus, is one of the most serious pests of Norway spruce (NS, Picea abies), with ...

Genetic architecture of phenological, morphological, and phytochemical traits in Cannabis landraces

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Despite its long history of cultivation and diverse applications, Cannabis sativa remains underexplored at the genomic level, particularly in landrace populations that harbor untapped genetic diversity. In this study, we investigated the genetic architecture of 145 Iranian cannabis landrace accessions, including both male and female plants ...

Comprehensive transduceromic profiling of NOP receptor ligands at different Gα subunits

British Journal of Pharmacology, Volume 183, Issue 12, Page 3195-3212, June 2026.
Abstract Background and Purpose The nociceptin/orphanin FQ (N/OFQ) peptide receptor (NOP) is an opioid receptor family member with distinct pharmacology and broad therapeutic potential. NOP receptors regulate functions such as nociception, stress reactivity, reward, mood, autonomic tone, immunity and sleep/wake cycle.
