Expression of engineered wheat dwarf virus in seed‐derived embryos

Physiologia Plantarum, 1990
Delivery of DNA into dry and viable embryos of wheat by imbibition in DNA solution was detected by monitoring the transient expression of chimeric genes. The gene expression vectors used comprise of a neomycin phosphotransferase II (NPT II) reporter gene, under the control of various promoters or as part of a cloned plant virus genome.

Wheat resistome in response to barley yellow dwarf virus infection

Functional & Integrative Genomics, 2013
Barley yellow dwarf virus (BYDV) caused one of the most serious virus diseases of wheat (Triticum aestivum) worldwide. The wheat-Thinopyrum intermedium translocation line YW642 carries BYDV resistance gene Bdv2. To explore resistant wheat resistome in response to BYDV infection, we used Affymetrix GeneChip® Wheat Genome Arrays to analyze transcriptomes

Molecular and Ultrastructural Mechanisms Underlying Yellow Dwarf Symptom Formation in Wheat after Infection of Barley Yellow Dwarf Virus

International Journal of Molecular Sciences, 2018
peer reviewedWheat (Tritium aestivum L.) production is essential for global food security. Infection of barley yellow dwarf virus-GAV (BYDV-GAV) results in wheat showing leaf yellowing and plant dwarfism symptom.

Geminiviruses (wheat dwarf virus)

1992
Abstract Episomal (i.e. autonomously replicating) vectors derived from animal DNA viral sequences, and which can be maintained either transiently or permanently in cultured cells, are widely used in studies of transcriptional regulation in animals.

Temporal spread of wheat dwarf virus and mature plant resistance in winter wheat

Crop Protection, 2004
Abstract Wheat dwarf is a potentially severe disease of winter wheat. The causal agent is wheat dwarf virus (WDV), a geminivirus transmitted by the leafhopper Psammotettix alienus . Field surveys of WDV incidence and vector occurrence were conducted for 4 years in winter wheat fields in central Sweden.

Crystal structure of the wheat dwarf virus Rep domain

The FASEB Journal, 2020
The wheat dwarf virus Rep domain is an HUH‐endonuclease and is involved in rolling‐circle replication. HUH‐endonucleases, or HUH‐tags, form covalent protein‐ssDNA adducts by coordinating a divalent metal ion to cleave a specific ssDNA sequence and form a phosphotyrosine linkage.

Response of wheatgrasses and wheat � wheatgrass hybrids to barley yellow dwarf virus

Theoretical and Applied Genetics, 1989
Resistance to barley yellow dwarf virus (BYDV), manifested by low enzyme-linked immunosorbent assay (ELISA) values in plants exposed to viruliferous aphids, was identified in several wheatgrasses (Agropyron spp.). ELISA results were similar for root and leaf extracts of infested plants.

The Wheat dwarf virus in France: occurence and transmission

2011
The Wheat dwarf virus(WDV, genus Mastrevirus), transmitted by leafhoppers of the Psammotettix genus on a persistent mode, is one of the most severe virus disease on cereals. This virus has a wide range of host plants including Poaceae. The distribution of WDV in France is based on samplings of plant material and leafhoppers throuthough years 2007-2010.

Characterization of the host range of barley and wheat strains of Wheat dwarf virus

2017
Wheat dwarf virus (WDV, Geminiviridae family, Mastrevirus genus) is the causal agent of dwarfing, mottling and yellowing symptoms in wheat and barley. WDV is exclusively transmitted by leafhoppers from the genus Psammotettix in a persistent manner. The circular single-stranded DNA genome of WDV, of about 2.75-kb long, encodes two replication-associated
