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.

Sesquiterpenes of nine european liverworts from the genera, Anastrepta, bazzania, jungermannia, lepidozia and Scapania

, 1977
The essential oils of fourteen liverwort specimens from nine species of the Jungermanniales have been examined as to their sesquiterpenes. The barbatenes prove to be present in detectable amounts in all but one species. Bazzanene is frequently found with

Attraction of nocturnal scarab beetles by unusual floral volatiles in a Banksia (Proteaceae) with functionally diverse pollinators

Plant Biology, EarlyView.
Banksia attenuata (Proteaceae) attracts nocturnal scarab beetles with an unusual floral scent—the beetles pollinate the flower as they feed on pollen and nectar and mate on the inflorescences. Abstract Pollination by beetles has evolved multiple times in flowering plants but with relatively few plant species adapted specifically to pollination by ...

Molecular evolution of terpene synthase underlying the diversification of isoprene emission in Fagaceae

Plant Biology, EarlyView.
Isoprene emission in oaks originated from convergent adaptive evolution of terpene synthases, involving a substrate shift from monoterpene to isoprene production within a Fagaceae‐specific TPS lineage. Abstract Plants emit a wide range of volatile organic compounds, among which isoprene is the most abundant and atmospherically influential. Although oak

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Antifungal Sesquiterpenes from Cedrus deodara

, 2012
! Two new sesquiterpenes, (E)-(2S,3S,6R)-atlantone-2,3-diol (1) and (E)-(2S,3S,6S)-atlantone-2,3,6-triol (2), along with two known sesquiterpenes, atlantolone (3) and (E)-α-atlantone (4), were isolated from Cedrus deodara Loud. The structures of the

Chitosan‐induced modulation of secondary metabolism and stress tolerance in Salvia rosmarinus under combined drought and heat stress

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5989-6001, 15 August 2026.
Abstract BACKGROUND Abiotic stresses, particularly drought and elevated temperatures, negatively affect plant physiological and metabolic processes. This study investigated the effects of drought, heat, and combined stress on Salvia rosmarinus (rosemary), and evaluated foliar‐applied chitosan as a biostimulant.

Fast and Sensitive Measurement of Off‐Flavors in Recirculating Aquaculture Systems

Rapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Geosmin and 2‐methylisoborneol (2‐MIB) are odor‐active compounds responsible for earthy off‐flavors in fish, creating significant quality concerns in recirculating aquaculture systems (RAS). Their extremely low odor thresholds make rapid and highly sensitive detection essential for maintaining product quality and consumer acceptance ...

Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

Flavour and Fragrance Journal, Volume 41, Issue 4, Page 908-922, July 2026.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.
