Viral Infection Risk Driven by Ecological Trait Susceptibility to Habitat Heterogeneity

Molecular Ecology, Volume 35, Issue 14, July 2026.
ABSTRACT Traits for host exploitation that drive the transmission of disease and pathogen emergence are expressed in heterogenous environments. To advance the development of accurate forecasting of infection risk and emergence, determining constraints on ecological strategies for resource use by pathogens over a range of host communities is essential ...

Virome Analysis Deciphers the First Virus Occurrence in Melothria scabra, Revealing Two Potyviruses, Including a Highly Divergent Zucchini Yellow Mmosaic Virus Isolate [PDF]

The Plant Pathology Journal
Melothria scabra, an annual vine plant belonging to the family Cucurbitaceae, is usually found as a weed in agricultural ecosystems, making it a potential reservoir for crop viruses. Nonetheless, no plant virus has been documented to infect M.

Imprecise Cas12a/ssODN‐Mediated Editing of eIF4E1 Confers Dominant‐Negative Resistance to Potato Virus Y in Solanum tuberosum

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
Efforts to mimic the pepper PVY‐resistant pvr21 allele in potato using Cas12a‐mediated single‐stranded oligodeoxynucleotide (ssODN) editing of eIF4E1, while highlighting key technical limitations, shed light on a dominant‐negative PVY resistance mechanism.

Effects of Elevated CO2 on Bean Pod Mottle Virus Infection in Both Incompatible and Compatible Interactions With Phaseolus vulgaris L

Plant, Cell &Environment, Volume 49, Issue 7, Page 4493-4512, July 2026.
ABSTRACT Plant viruses cause significant crop losses, a situation that could worsen due to anthropogenic activities driving global climate change, one factor of which is the increase in atmospheric CO2 concentration. This study assessed the impact of elevated CO2 concentration (eCO2, 1000 vs. 400 ppm) on two genotypes of common bean (Phaseolus vulgaris

Highlights and prospects of potyvirus molecular biology

Journal of General Virology, 1992
The potyvirus group [named after its type member, potato virus Y (PVY)] is the largest of the 34 plant virus groups and families currently recognized (Ward & Shukla, 1991). It contains at least 180 definitive and possible members (or 30% of all known plant viruses) which cause significant losses in agricultural, pasture, horticultural and ornamental ...

Evaluation of Chilli Breeding Lines at Multiple Locations Reveals Differential Resistance to Potyvirus Species Across Asia

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Geographically structured populations of ChiVMV and PVMV strongly influenced the durability of potyvirus resistance in chilli across Asia. Multi‐location evaluation revealed that resistance gene combinations, particularly pvr1 + Pvr4E + pvr6 + CVMV3 and pvr1 + CVMV3, provided more stable resistance across diverse virus populations. ABSTRACT Potyviruses,

Frequent occurrence of recombinant potyvirus isolates

Journal of General Virology, 1996
We have performed a systematic search for recombination in the region encoding coat protein and the 3' non-translated region in natural isolates of potyviruses, the largest group of plant RNA viruses. The presence of recombination, and the localization of the cross-over points, were confirmed statistically, by three different methods. Recombination was
