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

open access: yesAnnals 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 ...

Barley yellow dwarf virus-GAV-derived vsiRNAs are involved in the production of wheat leaf yellowing symptoms by targeting chlorophyll synthase

open access: yesVirology Journal, 2020
Background Wheat yellow dwarf virus disease is infected by barley yellow dwarf virus (BYDV), which causes leaf yellowing and dwarfing symptoms in wheat, thereby posing a serious threat to China's food production.

Long‐term nitrogen enrichment mediates the effects of nitrogen supply and co‐inoculation on a viral pathogen

open access: yesEcology and Evolution, 2022
Host nutrient supply can mediate host–pathogen and pathogen–pathogen interactions. In terrestrial systems, plant nutrient supply is mediated by soil microbes, suggesting a potential role of soil microbes in plant diseases beyond soil‐borne pathogens and ...

A Modelling Framework to Estimate Vector Dispersal and Disease Spread in an Important Agricultural Pathosystem

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
A model of aphid‐vectored BYDV highlights the importance of the interaction between aphid and viral genetic and species diversity on the risk presented by crop disease. The modelling framework offers a tool to explore vector–virus–host interactions and both conventional and natural controls in a spatial context.

Can Mixed Intercropping Protect Cereals from Aphid-Borne Viruses? An Experimental Approach

open access: yesInsects, 2022
Intercropping, i.e., association of two or more species, is promising to reduce insect populations in fields. The cereal aphid Rhopalosiphum padi, a vector of the Barley yellow dwarf virus PAV (BYDV-PAV), represents a major threat for cereal grain ...

Efficacy of Wheat Insecticide Seed Treatments on Bird Cherry-Oat Aphids [PDF]

open access: yes, 2018
Bird Cherry-Oat Aphids, Rhopalosiphumpadi (Linnaeus), (BCOA) are a major agricultural pest for wheat due to their ability to transferBarley Yellow Dwarf Virus (BYDV), which can stunt growth when introduced to seedlings (Wegulo, 2013). These aphids, which

Temperature variability homogenized thermal responses in an ectotherm community along a European longitudinal gradient

open access: yesEcography, Volume 2026, Issue 2, February 2026.
Climate change, through rising temperatures, greater variability, and more frequent extremes, is reshaping insect phenology and thermal niches, with profound effects for pest outbreaks. Predicting these impacts requires a clear understanding of species and communities' responses across geographic gradients.

Fungal endophytes decrease aphid performance in grasses: effects on virus transmission? [PDF]

open access: yes, 2003
We examined how endophyte infection and nutrient availability affects the performance of bird-cherry aphid (Rhopalosiphum padi) in meadow fescue (Festuca pratensis).

Discovery of a Small Non-AUG-Initiated ORF in Poleroviruses and Luteoviruses That Is Required for Long-Distance Movement. [PDF]

open access: yes, 2015
Viruses in the family Luteoviridae have positive-sense RNA genomes of around 5.2 to 6.3 kb, and they are limited to the phloem in infected plants. The Luteovirus and Polerovirus genera include all but one virus in the Luteoviridae.

Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
This study examines if plant functional diversity dilutes plant virus prevalence in grass hosts and evaluates how virus prevalence influences net community and host production. Functional diversity did not mitigate or amplify virus prevalence. While we found that species relationships between virus prevalence and production varied, overall, virus ...
