Biotransformation of monoterpenols upon pre‐treatment with oregano essential oil vapour alleviates downy mildew susceptibility in grapevine leaves

Plant Biology, EarlyView.
Pre‐treatment of grapevine plants with oregano essential oil vapour alleviates downy mildew susceptibility by accumulation of monoterpenol glycosides. Abstract Grapevine downy mildew, caused by the oomycete Plasmopara viticola, is a destructive disease that causes major economic losses as most elite grapevine cultivars are susceptible to this pathogen.

Isolate-Dependent Inheritance of Resistance Against Pseudoperonospora cubensis in Cucumber

Agronomy, 2020
Six wild accessions of Cucumis sativum were evaluated for resistance against each of the 23 isolates of the downy mildew oomycete Pseudoperonospora cubensis. The isolates originated from Israel, Europe, USA, and Asia. C.

The Global South's OCBIL Theory Helps Elucidate Evolution, Ecology, and Conservation in Biological and Cultural Diversity

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
Ecological theory has been shaped disproportionately by studies conducted in young, disturbance‐prone, relatively fertile landscapes (YODFELs), mostly in the Global North. Yet, many megadiverse regions in the Global South are dominated by old, climatically buffered, infertile landscapes (OCBILs), resulting in fundamentally different patterns that ...

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, Volume 82, Issue 9, Page 8159-8170, September 2026.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

LURP1, a SARD1‐regulated protein, coordinates with the helper NLR ADR1 to promote plant immunity

New Phytologist, Volume 251, Issue 5, Page 2852-2866, September 2026.
The working model of LURP1 function in plant immunity. Upon pathogen infection, SARD1/CBP60g promotes the transcription of LURP1 directly. LURP1 likely functions as an adaptor protein that associates with the PRRs–BAK1 complexes at the plasma membrane (PM) while also interacts with the ADR1 family helper NLRs.

Cross‐Species Plasticity and Divergence Under Alkaline Soil Signature Conditions Differentiating PYE From FIT Target Transcripts in the Arabidopsis thaliana Ferrome

Plant, Cell &Environment, Volume 49, Issue 9, Page 6719-6736, September 2026.
ABSTRACT Soil pH is an influential abiotic environmental factor. Here, we identify responses to central stimuli associated with calcareous alkaline soils in Arabidopsis and comparatively explore the potential of the closely related Arabidopsis halleri for addressing how plants cope with local soil pH.
