Abstract (sommario):

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. Segregation of the transmission phenotype for both viruses in the F1 and F2 populations indicated that the transmission phenotype is under genetic control and that the parents are heterozygous for genes involved in transmission. The ability to transmit both viruses was correlated within the F1 and F2

Abstract (sommario):

Following the discovery of two new wheat virus diseases in the United States, the Great Plains region (Colorado, Kansas, Montana, Nebraska, North Dakota, Oklahoma, South Dakota, Texas, and Wyoming) of the National Plant Diagnostic Network (NPDN) initiated a project to measure the prevalence of five wheat diseases using indirect ELISA. Wheat streak mosaic virus (WSMV), Wheat mosaic virus (WMoV), and Triticum mosaic virus (TriMV) were found in all nine states. WSMV was the most prevalent, averaging 23 to 47% of samples each year. TriMV and WMoV were detected with WSMV (in up to 76% of the sample

Abstract (sommario):

Barley yellow dwarf virus (BYDV), transmitted by the wheat aphid, generates serious wheat yellow dwarf disease and causes great losses in agriculture. Induced resistance has attracted great attention over recent years as a biological method to control plant pathogens and herbivores. Protein elicitor PeaT1 induces defense response in plants against fungi, viruses, and aphids. In this study, wheat seeds and seedlings were soaked and sprayed with 30 μg/mL PeaT1, respectively. Then seedlings were inoculated with BYDV by viruliferous Schizaphis graminum to detect the control efficiency of PeaT1-ind

Wheat viruses including wheat streak mosaic virus, Triticum mosaic virus, and barley yellow dwarf virus cost substantial losses in crop yields every year. Although there have been extensive studies conducted on these known wheat viruses, currently, there is limited knowledge about all components of the wheat (Triticum aestivum L.) virome. Here, we determined the composition of the wheat virome through total RNA deep sequencing of field-collected leaf samples. Sequences were de novo assembled after removing the host reads, and BLASTx searches were conducted. In addition to the documented wheat

ABSTRACT Satellite RNAs usurp the replication machinery of their helper viruses, even though they bear little or no sequence similarity to the helper virus RNA. In Cereal yellow dwarf polerovirus serotype RPV (CYDV-RPV), the 322-nucleotide satellite RNA (satRPV RNA) accumulates to high levels in the presence of the CYDV-RPV helper virus. Rolling circle replication generates multimeric satRPV RNAs that self-cleave via a double-hammerhead ribozyme structure. Alternative folding inhibits formation of a hammerhead in monomeric satRPV RNA. Here we determine helper virus requirements and the effects

Abstract (sommario):

Noncoding sequences in plant viral genomes are well-known to control viral replication and gene expression in cis. However, plant viral and viroid noncoding (nc)RNA sequences can also regulate gene expression acting in trans, often acting like ‘sponges’ that bind and sequester host cellular machinery to favor viral infection. Noncoding sequences of small subgenomic (sg)RNAs of Barley yellow dwarf virus (BYDV) and Red clover necrotic mosaic virus (RCNMV) contain a cap-independent translation element that binds translation initiation factor eIF4G. We provide new evidence that a sgRNA of BYDV can

Abstract (sommario):

ABSTRACT Numerous RNA viruses generate subgenomic mRNAs (sgRNAs) for expression of their 3′-proximal genes. A major step in control of viral gene expression is the regulation of sgRNA synthesis by specific promoter elements. We used barley yellow dwarf virus (BYDV) as a model system to study transcriptional control in a virus with multiple sgRNAs. BYDV generates three sgRNAs during infection. The sgRNA1 promoter has been mapped previously to a 98-nucleotide (nt) region which forms two stem-loop structures. It was determined that sgRNA1 is not required for BYDV RNA replication in oat protoplast

ABSTRACT Many positive-strand RNA viruses generate 3′-coterminal subgenomic mRNAs to allow translation of 5′-distal open reading frames. It is unclear how viral genomic and subgenomic mRNAs compete with each other for the cellular translation machinery. Translation of the uncapped Barley yellow dwarf virus genomic RNA (gRNA) and subgenomic RNA1 (sgRNA1) is driven by the powerful cap-independent translation element (BTE) in their 3′ untranslated regions (UTRs). The BTE forms a kissing stem-loop interaction with the 5′ UTR to mediate translation initiation at the 5′ end. Here, using reporter mRN

We examined the virus transmission characteristics of several distinct populations and various developmental stages of the aphid. Seven well-characterized S. graminum biotypes maintained at the USDA-ARS laboratory in Stillwater, OK, and two biotypes maintained in New York (one collected in Wisconsin and the other collected in South Carolina) were tested for their ability to transmit five viruses that cause barley yellow dwarf disease (BYD).

Abstract (sommario):

Surveys on viruses associated with Barley Yellow Dwarf (BYD) and their vectors were carried out in Algerian cereal areas (Guelma, Constantine, Algiers, Sidi-belabes, Adrar) in 1997 and 1998. Rhopalosiphum padi was present in all zones of culture, whereas R. maidis, Sitobion avenae, S. fragariae and Schizaphis graminum had only local distributions. In most areas BYD-like symptoms, i.e. dwarfing and yellowing of barley (Hordeum vulgare), dwarfing and reddening of oat (Avena sativa) and wheat (Triticum aestivum), were observed. Serological tests were done on these crops using DAS-ELISA (RMV and S

Abstract (sommario):

In recent years viral diseases have become more frequent on cereals in Hungary. In the breeding nursery of the Martonvásár Institute, which contains stocks with very diverse genetic backgrounds, wheat suffered major attacks by viruses in 1972, 1976, 1980, 1981, 1982, 1986, 1990, 1996 and 1998. The winter barley plots incurred great damage in 1989 and 1990, while a large proportion of the durum wheat was destroyed in 1996. In 1982 barley yellow dwarf virus caused an epidemic in Fejér County and on many farms the damage was so great that the fields had to be ploughed up. The following nine virus

Abstract (sommario):

Barley Yellow Dwarf (BYD) is a serious Luteovirus disease that affects small grain production worldwide. The aphid-transmitted virus (BYDV) infects practically all members of the Graminae (Poaceae) and is responsible for serious losses in cultivated species such as barley, wheat and oats. The study of BYD is complex, as it involves interactions among a vector, a plant and a virus. Hence, symptom expression is highly dependent on environmental conditions, serotypes plant genetic background and physiological stage of inoculation. Consequently, tolerance to BYDV is also difficult to study and und

Abstract (sommario):

Barley yellow dwarf (BYD) has been described as the most devastating cereal grain disease worldwide causing between 11% and 33% yield loss in wheat fields. There has been little focus on management of the disease in the literature over the past twenty years, although much of the United States still suffers disease outbreaks. With this review, we provide the most up-to-date information on BYD management used currently in the USA. After a brief summary of the ecology of BYD viruses, vectors, and plant hosts with respect to their impact on disease management, we discuss historical management tech

Abstract (sommario):

Abstract Modern pasture management of perennial ryegrass results in reduced reseeding and increased reliance on asexual tiller multiplication. This may exacerbate viral impact by providing longer-living hosts to exploit, thus the effect of ryegrass age on sward performance and viral load was investigated. Genetically similar 10 year old field plants and 10 year old seed were used to produce 'mini-swards' of 'old' (tiller derived) and 'young' (seed derived) ryegrass lines. Dry matter yield and viral load (ryegrass mosaic, and barley yellow dwarf) were assessed over 10 months. For all lines the

Abstract (sommario):

Reliable detection and quantification of barley and cereal yellow dwarf viruses (YDVs) is a critical component in managing yellow dwarf diseases in small grain cereal crops. The method currently used is enzyme-linked immunosorbent assay (ELISA), using antisera against the coat proteins that are specific for each of the various YDVs. Recently, quantitative real-time reverse-transcription polymerase chain reaction (Q-RT-PCR) has been used to detect bacterial and viral pathogens and to study gene expression. We applied this technique to detect and quantify YDVs using primers specific for Barley y

Abstract (sommario):

The lack of suitable genes in existing wheat germplasm collections makes breeding for specific traits a difficult task. Although tolerance to barley yellow dwarf viruses (BYDV) has been reported in wheat accessions, there are no suitable levels of resistance to BYDV, so genes are sought from wild relatives. The ability for Thinopyrum species to inhibit replication of BYDV makes them attractive sources of resistance for germplasm development. Breeding programs are exploiting Thinopyrum species to develop wheat germplasm resistant to BYDV. The transfer of genes from Thinopyrum into wheat by wide
