The Flavonoids Daidzein and Genistein Induce Wall‐Deficient Cell Formation in Streptomyces coelicolor Under Hyperosmotic Stress

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
Plant‐derived isoflavones (daidzein and genistein) function as chemical signals that induce stress‐dependent formation of wall‐deficient cells (S‐cells) in Streptomyces coelicolor. ABSTRACT Streptomycetes exhibit a complex multicellular life cycle, including programmed cell death and hyphal differentiation, and can generate extracellular vesicles and ...

Elucidating R‐gene‐mediated resistance to wheat dwarf virus in Triticum aestivum genotypes

Annals of Applied Biology, Volume 188, Issue 3, Page 947-961, May 2026.
This study investigates R‐gene‐mediated resistance to wheat dwarf virus (WDV) among different wheat genotypes. Following inoculation with Psammotettix alienus (leafhoppers) and the subsequent appearance of characteristic symptoms such as yellowing and dwarfing, phenotypic responses were evaluated alongside molecular analyses, including quantification ...

Dose‐Dependent Effect of Plant Volatiles on the Oviposition Preference of the Corn Leafhopper Dalbulus maidis

Journal of Applied Entomology, Volume 150, Issue 4, Page 497-505, May 2026.
ABSTRACT Maize (Zea mays L.) is a major annual crop cultivated worldwide. In the Americas, the corn leafhopper Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae) is a key pest of this crop, causing direct damage to plants through phloem feeding and indirect damage by transmitting phytopathogens.

When Does Fungicide Use Pay Off in Maize? Evidence From Low Foliar Disease Pressure Environments in Southern Brazil

Journal of Phytopathology, Volume 174, Issue 3, May/June 2026.
ABSTRACT Foliar fungicides are widely used in maize production in southern Brazil, yet their economic justification under low disease pressure remains uncertain. We synthesised yield and economic responses to a fungicide programme using a random‐effects meta‐analytic approach based on 19 multi‐environment trials conducted across the first and second ...

‘Candidatus Liberibacter asiaticus’ Effector SDE4250 Targets Citrus Proteasome Protein RPN10 to Inhibit Salicylic Acid‐Mediated Citrus Immunity

Molecular Plant Pathology, Volume 27, Issue 5, May 2026.
SDE4250 suppressed 26S proteasome activity by targeting CsRPN10 and enhancing its degradation via the proteasome pathway. This impairment of proteasome function subsequently attenuates SA‐mediated defence responses, thereby increasing citrus susceptibility to promote CLas infection.

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

Plant 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.
