BpWRKY6 regulates insect resistance by affecting jasmonic acid and terpenoid synthesis in Betula platyphylla

Plant Biotechnology Journal, EarlyView.
Summary Forest pests and diseases pose serious threats to the sustainable development of forestry. Plants have developed effective resistance mechanisms through long‐term evolution. Jasmonic acid and terpenoids play important roles in the defence response of plants against insects.

A Global Meta‐Analysis of Water Use Efficiency Proxies Reveals That UV Radiation Decreases Transpiration Without Improving WUE

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant water use efficiency (WUE) links physiological processes to ecosystem‐scale carbon and water cycles, making it a crucial parameter for climate change adaptation modelling. Climate and stratospheric ozone dynamics expose plants to varying intensity of ultraviolet‐B radiation (UV‐B), which affects stomatal function and transpiration.

Exogenous stimulation of Tanacetum vulgare roots with pipecolic acid leads to tissue‐specific responses in terpenoid composition

Plant Biology, EarlyView.
Tissue‐specific changes in terpenoid patterns in tansy are induced by simulated induction of systemic acquired resistance using pipercolic acid. Abstract Tanacetum vulgare L., tansy, is a perennial plant with highly variable terpenoid composition, with mono‐ and sesquiterpenoids being the most abundant.

Ontogeny and organ‐specific steroidal glycoside diversity is associated with differential expression of steroidal glycoside pathway genes in two Solanum dulcamara leaf chemotypes

Plant Biology, EarlyView.
Steroidal glycoside diversity among organs across ontogeny in relation to candidate gene expression in two Solanum dulcamara chemotypes. Abstract Solanaceous plants, such as Solanum dulcamara, produce steroidal glycosides (SGs). Leaf SG profiles vary among S.

First line of defence: Eucalyptus leaf waxes influence infection by an aggressive fungal leaf pathogen

Plant Biology, EarlyView.
Leaf wax compounds of Eucalyptus modulate the germination and infection of the leaf blight pathogen Teratosphaeria destructans. Abstract Leaf epicuticular waxes provide important anatomical and chemical defences against fungi that infect leaves. In this study we analysed the leaf wax composition of Eucalyptus grandis × Eucalyptus urophylla hybrids with

Intraspecific and intra‐individual chemodiversity and phenotypic integration of terpenes across plant parts and development stages in an aromatic plant

Plant Biology, EarlyView.
The terpene composition and chemodiversity of Tanacetum vulgare differ intraspecifically on a spatial and temporal scale, whereby the differences largely depend on the investigated component of chemodiversity. Abstract Some plant species produce an extraordinary diversity of specialized metabolites.

Chemical, morphological, and genetic characterization of the floral scent and scent‐releasing structures of Gynandropsis gynandra (Cleomaceae, Brassicales)

Plant Biology, EarlyView.
The flowers of African and Asian Gynandropsis gynandra accessions differ in fragrance and epidermal cell morphology (i.e., papillae). Abstract Flowering plants showcase a remarkable diversity in floral fragrances, colours, and structures, which function harmoniously as signals to attract and guide pollinators. Like visual signals, the scents emitted by

Ethnoveterinary Practices Related to Captive Elephants in Sauraha, Chitwan, Nepal

Veterinary Medicine and Science, Volume 11, Issue 4, July 2025.
The study documented 42 plant species from 26 families used for treating 27 ailments of captive elephants in Sauraha, Nepal. Leaves were the most frequently used plant part, and the most common preparation method was paste formulation, followed by raw, juice, powder, roast, and decoction forms.

Pharmacophagy in insects: Ecological and evolutionary perspectives on the non‐nutritional use of plant specialized metabolites

Entomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 661-673, July 2025.
Insects interact with plants not only for nutrition but also to actively seek plant specialized metabolites (PSMs) for chemical defense, reproduction, and self‐medication—a behavior known as pharmacophagy. This review examines how insects across diverse orders acquire PSMs from both food and non‐food plants for non‐nutritional benefits.
