Functional Transcomplementation between Wheat Dwarf Virus Strains in Wheat and Barley

Viruses, 2019
Wheat dwarf virus, transmitted by the leafhopper Psammotettix alienus in a persistent, non-propagative manner, infects numerous species from the Poaceae family. Data associated with wheat dwarf virus (WDV) suggest that some isolates preferentially infect

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 ...

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 [PDF]

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.

Variation in susceptibility to Wheat dwarf virus among wild and domesticated wheat. [PDF]

PLoS ONE, 2015
We investigated the variation in plant response in host-pathogen interactions between wild (Aegilops spp., Triticum spp.) and domesticated wheat (Triticum spp.) and Wheat dwarf virus (WDV).

Wheat Dwarf Virus as a Modulator of Multi-Stress Responses in Wheat. [PDF]

Physiol Plant
ABSTRACT Wheat dwarf virus (WDV) is an emerging constraint to cereal production whose epidemiological significance has intensified under climate change. Rising temperatures, extended vector activity, and the expansion of Psammotettix alienus into new regions have increased both the frequency and severity of WDV outbreaks.

F-actin dynamics in midgut cells enables virus persistence in vector insects. [PDF]

Mol Plant Pathol, 2022
Biphasic dynamics of F‐actin mediated by the ADF–CP interaction may play an important role in controlling virus entry and the virus accumulation level required for persistent transmission while maintaining the health of the vector. Abstract Hemipteran insects that transmit plant viruses in a persistent circulative manner acquire, retain and transmit ...

The crystal structure of the human smacovirus 1 Rep domain. [PDF]

Acta Crystallogr F Struct Biol Commun, 2023
The structure of the human smacovirus 1 Rep domain was obtained at 1.33 Å resolution. This new HUH endonuclease offers a new ssDNA‐binding sequence specificity that will be exploited to increase orthogonality among Rep families.Replication initiator proteins (Reps) from the HUH endonuclease family process specific single‐stranded DNA sequences to ...

Cas9-Rep fusion tethers donor DNA in vivo and boosts the efficiency of HDR-mediated genome editing. [PDF]

Plant Biotechnol J
Summary Genome editing based on the homology‐directed repair (HDR) pathway enables scar‐free and precise genetic manipulations. However, the low frequency of HDR hinders its application in plant genome editing. In this study, we engineered the fusion of Cas9 and a viral replication protein (Rep) as a molecular bridge to tether donor DNA in vivo, which ...
