Enzymatische Acylierung von Sterin-14C-Glucosid durch ein lösliches Enzym aus Karotten

CHIMIA, 1970
A soluble enzyme preparation from homogenized carrots (Daucus carota L.) catalyzes the formation of acylated steryl 14C-glucoside from steryl 14C-glucoside when either mono- or digalactosyl diglyceride is supplied as acyl donor.

Multi‐Induction Strategies in Crops: Mechanisms, Synergistic Effects, and Sustainable Applications for Enhanced Secondary Metabolite Production

Food Frontiers, Volume 7, Issue 4, July 2026.
This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...

PolyProline Predictor: A web server for empirical sequence‐based prediction of polyproline II helices

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Polyproline II (PPII) helices are extended left‐handed secondary structures increasingly recognized for their roles in molecular recognition, signaling and within intrinsically disordered regions of proteins. Despite their functional importance, predicting regions with propensity to form PPII helices from sequence alone remains challenging due

Toxicity of aqueous extracts of Ilex paraguariensis A.St.‐Hil. about Euphorbia heterophylla L.

Pest Management Science, Volume 82, Issue 7, Page 6196-6206, July 2026.
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.

Intraspecific trait variation responds consistently to global change drivers and mediates herbivory across unrelated plant species

Journal of Ecology, Volume 114, Issue 7, July 2026.
In classic trait‐based approaches, traits reflect different plant strategies that evolved over long‐term evolutionary timescales. The study indicates that these trade‐offs also emerge consistently across populations within single species, yielding similar ecological consequences.

Do Laboratory‐Reared Flies Perform Differently as Pollinators? Morphology, Behaviour and Pollination Performance of Eristalis tenax (Syrphidae)

Journal of Applied Entomology, Volume 150, Issue 6, Page 716-727, July 2026.
ABSTRACT Flies (Diptera) are important pollinators in global agriculture, yet little is known about how intraspecific trait variation influences their pollination performance. We compared morphological traits, foraging behaviour and pollination‐related performance metrics between laboratory‐reared (hereafter lab‐reared) and wild populations of ...

Insectary Plant Species Preferences of Predators and Parasitoid Families in a Mediterranean Horticultural Agroecosystem

Journal of Applied Entomology, Volume 150, Issue 6, Page 803-815, July 2026.
ABSTRACT The use of insectary plants to provide alternative food and shelter resources for enhancing natural enemy activity has been established as a common practice in IPM. Candidate flowering plant species have been screened and evaluated for their contribution to enhance life parameters of beneficial insects.
