Molecular evolution and phylogeographic analysis of wheat dwarf virus [PDF]

Frontiers in Microbiology
Wheat dwarf virus (WDV) has caused considerable economic loss in the global production of grain crops. Knowledge of the evolutionary biology and population history of the pathogen remain poorly understood.

Regulation of MSV and WDV virion-sense promoters by WDV nonstructural proteins: a role for their retinoblastoma protein-binding motifs

Virology, 2003
In this work we demonstrate that wheat dwarf virus (WDV) RepA can activate WDV and maize streak virus (MSV) virion (V)-sense expression in plant tissues. Rep alone does not have any effect on the silent WDV promoter and it represses the basal MSV promoter activity.

CRISPR/Cas9-Mediated Resistance to Wheat Dwarf Virus in Hexaploid Wheat (Triticum aestivum L.) [PDF]

Viruses
Wheat dwarf virus (WDV, genus Mastrevirus, family Geminiviridae) is one of the causal agents of wheat viral disease, which severely impacts wheat production in most wheat-growing regions in the world.

Widely-based full-genome analyses enable development of universal and strain-specific PCR toolkit for wheat dwarf virus detection, revealing new alternative hosts and challenging strain-host specificity [PDF]

Plant Methods
Background Wheat dwarf virus (WDV) is a destructive cereal virus causing significant yield losses in wheat and barley. It is transmitted by the leafhopper Psammotettix alienus and can persist in wild grasses between growing seasons, making reliable ...

Alanine scan of WDV Rep reveals its ssDNA binding mechanism

The FASEB Journal, 2020
HUH endonucleases (dubbed “HUH‐tags”) are small protein domains capable of forming covalent adducts with ssDNA in a sequence‐specific manner. The active site of HUH endonucleases utilizes a conserved histidine‐hydrophobic‐histidine motif to coordinate a metal ion that stabilizes a nucleophilic tyrosine necessary for phosphodiesterase activity.

Population dynamics of the leafhopper Psammotettix alienus Dahlb. and two-year investigations into the occurrence of Wheat dwarf virus (WDV) in crops of winter barley located in the Middle German Dry Region, Germany

Plant Protection Science, 2002
From 2000 to 2001 the population dynamics of Psammotettix alienus Dahlb. were recorded using a sweep-net or a biocoenometer. The investigations were carried out in Zscherben near Halle (Middle German Dry Region). The imagines of the first generation of P.

Comparition of the Nucleotide Sequences of Wheat Dwarf Virus (WDV) Isolates from Hungary and Ukraine

Polish Journal of Microbiology, 2011
Wheat dwarf virus (WDV) is the most ubiquitous virus in cereals causing huge losses in both Hungary and Ukraine. The presence of barley-and wheat-adapted strains has been confirmed, suggesting that the barley strain is restricted to barley, while the wheat strain is present in both wheat and barley plants. Five WDV isolates from wheat plants sampled in

Occurrence and Molecular Characteristics of Polerovirus BVG Isolates from Poland [PDF]

Pathogens
Barley virus G (BVG), the species Polerovirus BVG, within the genus Polerovirus in the family Solemoviridae, represents a new threat to cereal crops in Poland. It was first identified in 2022–2023 using high-throughput sequencing in pooled barley samples

SPREAD OF WHEAT DWARF VIRUS (WDV) ON THE SOUTH OF UKRAINE

Microbiology&Biotechnology, 2011
На посівах пшениці і ячменю південного регіону України виявлено вірус карликовості пшениці (ВКП). Вірус ідентифіковано за допомогою імуноферментного аналізу (IФА) і полімеразної ланцюгової реакції (ПЛР). Проаналізовано поширення вірусу, вивчено сортову чутливість злакових культур до ВКП.
