Temperature interacts with jack pine host defences to influence the growth of mountain pine beetle‐associated fungi

Agricultural and Forest Entomology, Volume 28, Issue 4, Page 525-534, November 2026.
Optimal growing temperatures varied with mountain pine beetle‐associated fungal species. There was only a marginal impact of temperature on the response of fungi to defensive monoterpenes of novel host pine. Interspecific facilitation occurred for Leptiographuim longiclavatum when grown in Ophiostoma montium‐induced treatments at optimal temperatures ...

Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress

Plant, Cell &Environment, Volume 49, Issue 11, Page 8437-8453, November 2026.
ABSTRACT Among various plant defence strategies, trichomes are tiny hair‐like structures on the epidermis that aid in defence, environmental adaptation and the production of valuable secondary metabolites. This review features trichomes as frontline guards for plant survival, integrating their structural, physiological and metabolic roles in ...

Seasonal Variation and Resin Composition in the Andean Tree Austrocedrus chilensis

Molecules, 2014
Little is known about the changes in resin composition in South American gymnosperms associated with the different seasons of the year. The diterpene composition of 44 resin samples from seven Austrocedrus chilensis (Cupressaceae) trees, including male ...

Water Deficit Does Not Compromise the Resistance to Insect Herbivores in Plants Associated With Fungal Endophytes Able to Produce Bioactive Alkaloids

Plant, Cell &Environment, Volume 49, Issue 11, Page 8481-8496, November 2026.
ABSTRACT Plants growing in nature are exposed to multiple abiotic and biotic stressors that sometimes occur sequentially. We hypothesised that drought will not compromise the resistance levels to herbivores when plants are associated with Epichloë endophytes able to produce bioactive alkaloids. Lolium perenne plants without (nil) and with Epichloë LpTG‐

Trachylobane and kaurane diterpenes from Croton floribundus spreng

Química Nova, 2013
A new trachylobane diterpene ent-trachyloban-18,19-diol (1) was isolated from root bark of Croton floribundus, along with known diterpenes ent-trachyloban-19-oic acid (2), 15b-hydroxy-ent-trachyloban-19-oic acid (3), ent-trachyloban-19-ol (4), ent-kaur ...

Chemoenzymatic Synthesis of (4R,7R)‐Zingiberene Enables Construction of nor‐Sesquiterpene Semiochemical Analogs

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
A five‐enzyme chemoenzymatic synthesis of the insect‐repellent (4R,7R)‐zingiberene from the wild tomato (Solanum habrochaites) has been developed. This approach enabled the elucidation of the sesquiterpene synthase cyclization mechanism of (2Z,6Z)‐farnesyl pyrophosphate and bypasses classic biosynthetic constraints of prenyltransferase chain extension ...

Gastroprotective Mechanisms of Action of Semisynthetic Carnosic Acid Derivatives in Human Cells

Molecules, 2014
Carnosic acid (CA) and its semisynthetic derivatives display relevant gastroprotective effects on HCl/ethanol induced gastric lesions in mice. However, little is known on the mechanisms of action of the new compounds.

Evolutionäre, funktionelle und mechanistische Charakterisierung mikrobieller Terpensynthase‐ähnlicher Gene aus Springschwänzen

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Eine Genomanalyse zeigte das Vorkommen zahlreicher Terpensynthasen des bakteriellen Typs in Springschwänzen. Vier Enzyme aus Sinella curviseta wurden funktionell charakterisiert, was zur Isolierung mehrerer Verbindungen führte, darunter Sinellenether, der erste identifizierte Diterpenether einer Terpensynthase mit einem neuartigen Grundgerüst.
