Water Deficit Does Not Compromise the Resistance to Insect Herbivores in Plants Associated With Fungal Endophytes Able to Produce Bioactive Alkaloids

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants growing in nature are exposed to multiple abiotic and biotic stressors that sometimes occur sequentially. We hypothesised that drought will not compromise the resistance levels to herbivores when plants are associated with Epichloë endophytes able to produce bioactive alkaloids. Lolium perenne plants without (nil) and with Epichloë LpTG‐

Leaf Structure and Hormonal Balance Modulate Host‐Specificity and Pathogenicity of Botrytis cinerea

Plant, Cell &Environment, EarlyView.
ABSTRACT Botrytis cinerea, a highly successful necrotrophic fungal plant pathogen, demonstrates a remarkably broad host range, yet the precise factors governing its host specificity and its ability to coexist non‐pathogenically with plants remain unclear. This study systematically assessed host preference in a series of B. cinerea agricultural isolates,

Effects of Atmospheric CO2 Levels on the Susceptibility of Maize to Diverse Pathogens

Plant, Cell &Environment, EarlyView.
ABSTRACT Rising atmospheric CO2 has significant implications for crop productivity and food security. Based on studies in C3 plants, elevated CO2 (eCO2) can shape plant‐pathogen interactions, although the outcomes are often variable. The question of how eCO2 influences immunity and disease development in C4 plants, such as the globally important cereal

(3R, 7S)-11-hydroxy-jasmonic acid is a major oxidative shunt product of jasmonic acid catabolism in Arabidopsis thaliana

Nature Communications
Jasmonoyl-L-isoleucine (JA-Ile) is a pivotal oxylipin hormone that coordinates growth-defense trade-offs, and its precursor jasmonic acid (JA) is therefore subject to tight metabolic control.

Airborne Immunity: A Bacterial Volatile Primes Plant Defenses by Unlocking a Phytoalexin Biosynthetic Checkpoint

Plant, Cell &Environment, EarlyView.
ABSTRACT Microbial volatile organic compounds (mVOCs) enable plants to perceive microbial activity prior to physical contact, yet the contribution of individual bacterial volatiles to immune signalling and disease resistance remains incompletely understood.

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.

Airborne Methyl Jasmonate is Metabolized to Jasmonic Acid and 12-Hydroxyjasmonic Acid, and Induces Jasmonate Biosynthesis in Marchantia polymorpha

Airborne Methyl Jasmonate is Metabolized to Jasmonic Acid and 12-Hydroxyjasmonic Acid, and Induces Jasmonate Biosynthesis in Marchantia polymorpha
Methyl jasmonate (MeJA) is a volatile jasmonate compound commonly used to induce defense responses in spermatophytes. This study reports that airborne MeJA-d(3), deuterated MeJA, increases the levels of (dinor-)12-oxo-phytodienoic acids [(dn-)OPDAs] and jasmonic acid (JA) as well as JA-d(3) and 12-hydroxyjasmonic acid-d(2) (12-OH-JA-d(2)), MeJA-d(3 ...

Jasmonic Acid Oxidases (JAO) define a new branch in jasmonate metabolism towards 11OH-jasmonic acid and its glucosylated derivative

Abstract Jasmonates (JAs) occur in plants as a group of related compounds undergoing complex metabolic conversions that shape signatures unique to a given organ or physiological status. Previous studies have shown that several JAs result from direct or indirect catabolism of the master hormonal regulator jasmonoyl ...

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

Pest Management Science, Volume 82, Issue 9, Page 8499-8511, September 2026.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.
