Control of barley yellow dwarf virus in cereals [PDF]

New Zealand Journal of Agricultural Research, 1963
Abstract 1. Barley yellow dwarf virus (BYDV) is the most important disease affecting cereal crops in New Zealand. 2. Losses from BYDV in the total wheat crop have been up to 25 per cent in recent years. 3.

Achievements and prospects of wheat breeding for disease resistance

Czech Journal of Genetics and Plant Breeding, 2002
Achievements and prospects of wheat breeding for disease resistance in the world and in the Czech Republic are reviewed. Attention is paid to rusts, powdery mildew, leaf blotch, glume blotch, tan spot, fusarium head blight, common and dwarf bunt, eyespot,

Low-cost paper can be used in tissue-blot immunoassay for detection of cereal and legume viruses

Phytopathologia Mediterranea, 2002
In an effort to reduce the cost of virus assays, different types of regular paper were evaluated as possible replacements for the commonly used nitrocellulose membrane (NCM) as the solid phase in the tissue-blot immunoassay (TBIA) used to detect Alfalfa ...

Reconsidering the importance of Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) as a crop pest

Agricultural and Forest Entomology, EarlyView.
Four‐year field monitoring and laboratory studies revealed M. dirhodum occurs regularly in barley with high reproductive potential and extended adult longevity. Populations peaked during vulnerable crop stages, creating optimal conditions for BYDV transmission during critical infection windows. M.

First Detection of Wheat dwarf virus in Barley in Spain Associated with an Outbreak of Barley Yellow Dwarf

Plant Disease, 2006
Severe dwarfing, yellowing, and crop failure were observed on barley in northeastern Spain during March and April of 2003. Leaves from 106 plants collected from 15 barley fields were analyzed using enzyme-linked immunosorbent assay (ELISA) with commercial antisera (Loewe Biochemica, Munich) specific for Barley mild mosaic virus (BaMMV), Barley yellow ...

The Evaluation of Wheat Cultivar Resistance and Yield Loss Thresholds in Response to Barley Yellow Dwarf Virus-PAV Infection

Agriculture, 2020
The PAV strain of barley yellow dwarf virus (BYDV) is one of the causal agents of yellow dwarf disease in cereals. The use of germplasm resistant to BYDV is generally regarded as the most effective means of controlling damage caused by this pathogen.

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

The ZmRACK1–ZmCDPK7–ZmAPX1 module regulates plant antiviral immunity

Journal of Integrative Plant Biology, EarlyView.
In maize, ZmRACK1 acts as a scaffold protein that bridges the cyclin‐dependent kinase ZmCDPK7 and the ascorbate peroxidase ZmAPX1, promoting ZmAPX1 activity to mitigate MCMV infection. Upon viral infection, P31 obstructs formation of the ZmRACK1‐ZmCDPK7‐ZmAPX1 complex, inhibiting ZmCDPK7‐mediated ZmAPX1 activity and promoting reactive oxygen species ...

The TaRNS4–TaPP2C10 module regulates wheat resistance to stripe rust through RNA degradation and MAPK cascades

Journal of Integrative Plant Biology, EarlyView.
In wheat, phosphorylation of the S‐like RNase TaRNS4 mediated by the kinase TaRLK5 promotes its degradation of Puccinia striiformis f. sp. tritici RNA in the apoplast, enhancing resistance to stripe rust. TaRNS4 can hijack phosphatase TaPP2C10 to relieve its dephosphorylation of TaMAPK6, thereby activating MAPK‐mediated immune responses. ABSTRACT RNase

Differential Impacts of Virus Diversity on Biomass Production of a Native and an Exotic Grass Host.

PLoS ONE, 2015
Pathogens are common and diverse in natural communities and have been implicated in the success of host invasions. Yet few studies have experimentally measured how pathogens impact native versus exotic hosts, particularly when individual hosts are ...
