Screening potential insect vectors in a museum biorepository reveals undiscovered diversity of plant pathogens in natural areas

Ecology and Evolution, 2021
Phytoplasmas (Mollicutes, Acholeplasmataceae), vector‐borne obligate bacterial plant parasites, infect nearly 1,000 plant species and unknown numbers of insects, mainly leafhoppers (Hemiptera, Deltocephalinae), which play a key role in transmission and ...

Global Crotonylome Profiling Identifies TaPRXIIB Crotonylation as a Modulator H2O2 Homeostasis in Wheat Resistance to Puccinia triticina

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
Global crotonylome profiling identifies TaPRXIIBK172 crotonylation as a key modification that modulates H2O2 homeostasis, reduces enzyme activity and enhances wheat resistance to leaf rust. ABSTRACT Wheat food security is severely threatened by Puccinia triticina infection.

Phytoplasma Effector SJP8 Suppresses Host Immunity by Promoting the Degradation of ZjMYB15 and ZjMYB86‐like to Perturb Jasmonic Acid and Hydrogen Peroxide Homeostasis in Jujube

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 ...

Dramatic transcriptional changes in an intracellular parasite enable host switching between plant and insect. [PDF]

PLoS ONE, 2011
Phytoplasmas are bacterial plant pathogens that have devastating effects on the yields of crops and plants worldwide. They are intracellular parasites of both plants and insects, and are spread among plants by insects.

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.
