Three Closely Related Spodoptera Species Similarly Affect Gene Expression and Phytohormone Levels but Differentially Induce Volatile Emissions in Maize

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants can perceive specific elicitors in the oral secretions (OS) of herbivorous insects and respond by increasing their defences. Whether plants can discriminate among similar herbivorous insect species and differentially modulate their defence responses against them is largely unknown.

Engineered Production of Hydroxycinnamoyl Tyramine Conjugates Limits the Growth of the Pathogen Pseudomonas syringae in Arabidopsis

Plant, Cell &Environment, EarlyView.
ABSTRACT Hydroxycinnamoyl tyramine conjugates are phenolamides produced by plants in response to pathogen attack and biotic stresses. Their proposed mechanisms of action include cytotoxicity towards pathogens, cell wall reinforcement to restrict pathogen proliferation, and signaling activity to trigger general stress responses.

Hypoxic and Fe‐Responses are Regulated by the ERFVII Factors and the PCO Branch of the N‐Degron Pathway According to Iron Availability

Plant, Cell &Environment, EarlyView.
ABSTRACT In plants, iron homeostasis and oxygen metabolism are strictly related, indeed several Fe‐requiring enzymes catalyze reactions that also involve O2 as a reagent, product, entry or end point of the pathway. Oxygen sensing itself relies on the Fe‐dependent enzymes Plant cysteine oxidases.

Phytohormonal and Transcriptomic Mechanisms of Multigenerational Stress Memory in Wheat Under Weed Competition

Plant, Cell &Environment, EarlyView.
ABSTRACT Multigenerational stress exposure induces stress memory in plants, influencing resource allocation, defence mechanisms, and productivity. Weed competition imposes both resource‐based (abiotic) and allelopathic (biotic) stress, engaging overlapping hormonal pathways.

Rhizobacteria‐Induced Systemic Priming Against Fungal Pathogens Involves Hydroxycinnamic Acid Amides

Plant, Cell &Environment, EarlyView.
ABSTRACT The rhizosphere, a narrow region of soil surrounding roots, contains diverse microorganisms with a composition that is distinct from the surrounding soil. Some rhizosphere bacteria can trigger a heightened state of immunity in the whole plant, termed Induced Systemic Resistance (ISR).

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.
