Competency for Yellow Dwarf Virus Transmission in the Rose‐Grain Aphid, Metopolophium dirhodum, Is Driven by Virus Species Not Vector Genotype

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Barley yellow dwarf virus transmission assays show that virus diversity, not vector diversity, is the main driver of competency in the rose‐grain aphid. ABSTRACT Yellow dwarf viruses (YDVs) are a group of aphid‐vectored viruses that affect cereal crops and cause yellow dwarf disease.

The Vulnerability of New Zealand Forage Plants to Incursions by New Pests, Pathogens and Weeds, and the Case for Greater Protection

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.

The Polerovirus Silencing Suppressor P0 Targets ARGONAUTE Proteins for Degradation [PDF]

Current Biology, 2007
Plant and animal viruses encode suppressor proteins of an adaptive immunity mechanism in which viral double-stranded RNA is processed into 21-25 nt short interfering (si)RNAs. The siRNAs guide ARGONAUTE (AGO) proteins so that they target viral RNA. Most viral suppressors bind long dsRNA or siRNAs and thereby prevent production of siRNA or binding of ...

Insights Into Sequences of Viral and Bacterial Origin in the Metatranscriptome of Centaurea cyanus L. Susceptible and Resistant to Acetolactate Synthase (ALS)‐Inhibiting Herbicides

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Metatranscriptomic analysis of Centaurea cyanus revealed diverse plant‐associated viral and bacterial sequences in herbicide‐susceptible and ‐resistant biotypes. While novel partitiviruses occurred independently of resistance status, differences in bacterial community composition may suggest a potential role of the plant microbiome in responses to ...

Do stylet‐borne aphid‐transmitted viruses share the same binding sites?

Annals of Applied Biology, Volume 188, Issue 1, Page 87-101, January 2026.
Here, we tested if different stylet‐borne aphid‐transmitted viruses can compete for the same binding sites within the aphid stylets. We conducted sequential transmission assays of a potyvirus (ZYMV) followed by a cucumovirus (CMV) using Aphis gossypii as a vector and melon and pepper as test plants.

A Field‐Based Investigation of the Association Between Cotton Leafroll Dwarf Virus and Bronze Wilt‐Like Responses in Upland Cotton in Georgia

Plant Pathology, Volume 75, Issue 1, January/February 2026.
In Georgia, commercial upland cotton cultivars that expressed bronze wilt‐like responses consistently showed high copy numbers of cotton leafroll dwarf virus (CLRDV) gene, particularly in late‐planted cotton. These observations parallel historical reports of bronze wilt and suggest an association between CLRDV infection and bronze wilt‐like symptom ...

Identification of Polerovirus Infecting Chili Pepper in Java

Jurnal Fitopatologi Indonesia
Infection of polerovirus in chili peppers has been reported from various parts of the world, including Indonesia. Pepper vein yellow virus (PeVYV), a member of genus Polerovirus were reported infecting chili plants in Bali, Java, and Aceh during 2012 to 2020. Recently, symptoms of the polerovirus infection, such as yellowing leaves with vein thickening,

Cover Crops and Flower Strip Plants as Potential Hosts for Sugar Beet‐Infecting Virus Yellows Species and Their Attractiveness to the Vector Myzus persicae

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Several common cover crops and flower strip plants are susceptible to BMYV, while susceptibility and attractiveness to Myzus persicae vary widely. These plants may act as virus reservoirs, emphasising the need to prevent green bridges. ABSTRACT Virus yellows (VY), caused by beet chlorosis virus (BChV), beet mild yellowing virus (BMYV) and beet yellows ...

Genetic Regulation of Polerovirus and Luteovirus Transmission in the Aphid Schizaphis graminum [PDF]

Phytopathology®, 2006
Sexual forms of two genotypes of the aphid Schizaphis graminum, one a vector, the other a nonvector of two viruses that cause barley yellow dwarf disease (Barley yellow dwarf virus [BYDV]-SGV, luteovirus and Cereal yellow dwarf virus-RPV, polerovirus), were mated to generate F1 and F2 populations.
