Beneficial rhizobacteria and virus infection modulate the soybean metabolome and influence the feeding preferences of the virus vector Epilachna varivestis

open access: yesNew Phytologist, Volume 250, Issue 4, Page 2599-2618, May 2026.
Summary Beneficial rhizobacteria and viral pathogens can both alter host plant phenotypes, yet little is known about how their simultaneous presence influences plant metabolism and species interactions. We investigated how two rhizobacteria, Bradyrhizobium japonicum and Delftia acidovorans, together with bean pod mottle virus (BPMV), shape soybean ...

5-Deoxynevadensin, a Novel Flavone in Sunflower and Aspects of Biosynthesis during Trichome Development

open access: yesNatural Product Communications, 2006
Fluorescent microscopy of sunflower glandular trichomes from anther appendages showed a strong autofluorescence, caused by flavonoids. Chemical analysis with NMR and HRMS lead to the identification of 7-hydroxy-6,8,4′-trimethoxyflavone, a novel 5 ...

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 2939-2955, May 2026.
ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.

Role of defense enzymes and phenolics in resistance of wheat crop (Triticum aestivum L.) towards aphid complex

open access: yesJournal of Plant Interactions, 2017
Herbivory damage leads to induction of rapid signals and responses in plants such as oxidative burst, accumulation of secondary metabolites and defensive proteins.

Beta-aminobutyric acid-induced resistance in grapevine against downy mildew: involvement of pterostilbene [PDF]

open access: yes, 2018
BABA, a non-protein amino acid, was used to induce resistance in grapevine against downy mildew. BABA-induced resistance was observed in the susceptible cv. Chasselas as well as in the resistant cv. Solaris.

The Cycocel effect on flavonoids content and phenylalanine ammonia-lyase (PAL) activity in buckwheat (Fagopyrum esculentum Moench.) plant

open access: yesStudia Biologica, 2012
Flavonoids are important secondary plant metabolites with many and diverse key functions that belong to largest class of substances produced by plants – phenylpropanoids. These substances are of interested among plant and animal biochemists, plant pathologists, geneticists and biotechnologists.

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

open access: yesPlant, Cell &Environment, Volume 49, Issue 5, Page 2394-2412, May 2026.
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.

Fungal Pathogen Activity and Stress‐Dependent Responses of Grapevine Wood to Esca and Drought

open access: yesPhysiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Biotic and abiotic stresses alter the physiology of perennial plants, with consequences for fungal endophytes and disease expression. In grapevine, drought inhibits esca disease expression, but the underlying molecular interactions between the plant and fungi are unknown. We combined wood metatranscriptomics, metabolomics, and metabarcoding to
