Chemical Compositions and Enantiomeric Distributions of Foliar Essential Oils of Chamaecyparis lawsoniana (A. Murray bis) Parl, Thuja plicata Donn ex D. Don, and Tsuga heterophylla Sarg.

open access: yesPlants
As part of our continuing interest in the essential oil compositions of gymnosperms, particularly the distribution of chiral terpenoids, we have obtained the foliar essential oils of Chamaecyparis lawsoniana (two samples), Thuja plicata (three samples ...

Composition and Seasonal Variation of the Essential Oil from from Hokkaido, Japan

open access: yesNatural Product Communications, 2009
The composition of the steam-distilled essential oil from the leaves of Abies sachalinensis (F. Schmidt) Mast. cultivated in Hokkaido (Japan) was studied by GC-MS. The seasonal variation in the main volatile constituents was also investigated.

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

open access: yesAgricultural and Forest Entomology, EarlyView.
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 ...

Systemic acquired resistance: an emerging role for jasmonates in local signal biogenesis, translocation and distal signal decoding

open access: yesNew Phytologist, EarlyView.
Jasmonate signalling underpins establishment of plant systemic acquired resistance (SAR). Activation of the hypersensitive response (HR) not only contains the pathogen but establishes broad spectrum resistance in unchallenged leaves. The strong burst of reactive oxygen/nitrogen species initiating the HR results in lipid peroxidation (illustrated by ...

Effects of Pistacia lentiscus Leaf‐Twig and Resin (Mastic) Oils on Salivary Flow in Healthy Individuals

open access: yesOral Diseases, EarlyView.
ABSTRACT Objective Pistacia lentiscus L. tree is known for its aromatic mastic gum containing terpenes α‐pinene and β‐myrcene, and has been applied as a traditional remedy in oral care for centuries. Previously, intranasal exposure to mastic resin volatiles increased salivary flow in healthy and dry‐mouth individuals. This study assessed the biological

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

open access: yesPlant, Cell &Environment, EarlyView.
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 ...

Glyphosate residues in soil alter herbivore‐induced plant volatiles and affect predatory insect behaviour

open access: yesPlant Biology, EarlyView.
Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.

Floral adaptation and modular trait evolution associated with a shift from bee to hummingbird pollination

open access: yesPlant Biology, EarlyView.
By comparing floral trait variation, integration and modularity in two sister species of Neotropical Costus with a pollination shift, we show that, despite pollination syndrome divergence, both species exhibit low floral variation and functional modularity, consistent with pollinator‐driven selection on traits mediating pollen transfer efficiency and ...
