Transcriptome and Hormone Regulations Shape Drought Stress‐Dependent Fusarium Head Blight Susceptibility in Different Barley Genotypes

Plant, Cell &Environment, EarlyView.
ABSTRACT Little is known about regulatory mechanisms that crop plants use to respond to combinations of abiotic and biotic stress. We analysed four barley genotypes under simultaneous Fusarium culmorum infection and drought stress by phenotyping for Fusarium Head Blight (FHB) disease, drought stress responses, hormone profiling and transcriptome ...

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

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.

Induced defence by a root hemiparasite increases host plant resistance against future infection

Plant Biology, EarlyView.
Infection by root hemiparasites can increase mortality of parasites during future infection, indicating induced host defence mechanisms. Abstract European grassland plants are frequently attacked by root hemiparasites. However, little is known about host defence responses to parasitism.

Organ‐specific terpenoid responses in Tanacetum vulgare are chemotype‐dependent

Plant Biology, EarlyView.
Common tansy varieties defend differently: some boost root chemicals against soil pests, while others release stronger leaf scents against aphids. Abstract Specialized metabolites such as terpenoids are known to mediate plant defence mechanisms. However, how terpenoid diversity governs inducible chemistry across organs remains poorly understood.

Resilience of floral scent emission after florivory

Plant Biology, EarlyView.
Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

Chemical treatment rescues reduced growth of the autoimmune mutant chs3‐2D without compromising its immune responses

Plant Biology, EarlyView.
We generated a compound by chemical modification that can efficiently rescue growth without decreasing the immune response of the chs3‐2D autoimmune mutants, thus chemically uncoupling its growth–defence trade‐off. Abstract Plant development in many species including Arabidopsis relies on the accurate balance between growth and defence.
