Phytoplasma occurrence in apple trees in the Czech Republic
Plant Protection Science, 2003 The presence of phytoplasmas in apple trees with proliferation symptoms, rubbery wood symptoms and no symptoms was determined by using polymerase chain reaction assays with primers amplifying phytoplasma 16S rRNA gene.

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.SJP8 suppresses plant immunity by perturbing JA and H2O2 homeostasis via the SJP8‐ZjMYB15/ZjMYB86‐like‐ZjJAIPHX1/ZjPOD43 module, leading to dwarfism and chlorosis. ABSTRACT ‘Candidatus Phytoplasma ziziphi’ infection causes severe damage to jujube (Ziziphus jujuba), inducing symptoms such as branch clustering, dwarfism, chlorosis and phyllody, leading ...

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 ...

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.

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 ...
