Control of barley yellow dwarf virus (BYDV) in oat and wheat and identification of a RAPD marker associated with BYDV tolerance in oat
… cm pot. Subpopulations were inoculated with the BYDV-PAV-IL strain (1) in the F$\sb2$ generations only, and (2) in the F$\sb2$ and F$\sb3$ generations, using viruliferous aphids (Rhopalosiphum padi L.). These subpopulations were compared to uninoculated subpopulations. Inoculation did not …

Point mutational examination of eukaryotic initiation factor 4E (eIF4E), inclusion bodies analysis, and Barley Yellow Dwarf Virus (BYDV) exonuclease resistant RNA structure mapping and prediction
… particularly in members of the genus Potyvirus. Resistance is thought to be conferred by disrupting the binding of the 5’ viral-encoded protein (VPg), covalently attached to the 5’ end of the Potyvirus genomic RNA, to eIF4E. RNAs of members of the genus Panicovirus, some Carmoviruses and …

Host-parasite interactions of barley yellow dwarf virus and oats: Physiological and immunological studies
The symptoms of barley yellow dwarf, chlorosis, stunting, and reduced heading or sterility in cereals, are readily confused with mineral deficiency or other cultural stresses. The pathogen, barley yellow dwarf virus (BYDV) is restricted in its host to phloem tissue, and phloem blockage leads to the …

Eukaryotic Initiation Factor 3 Interactions with Structural Elements of Barley Yellow Dwarf Virus Untranslated Regions Reveal Details of a New Cap-Independent Translation Initiation Model
<p>Barley Yellow Dwarf Virus (BYDV) is a positive strand RNA plant virus that translates without using a 5′ 7-methylguanosine cap or a 3′ poly-adenosine tail, features that are required for canonical mRNA translation. BYDV’s non-canonical translation relies on RNA structures in the 5′ and 3′ …

The Interaction Between Eukaryotic Translation Initiation Factor eIF4G and 3’ Cap Independent Translation Element of Barley Yellow Dwarf Virus Is Affected by Multiple Initiation Factors
<p>Barley Yellow Dwarf Virus (BYDV) lacks a 5’ (7-methyl guanosine) cap as well as a 3’poly A tail. Like many plant viruses, BYDV contains a cap independent translation element (CITE) in the 3’ untranslated region of the viral mRNA. BTE (Barley Yellow Dwarf Virus like cap-independent translation …

Genome-wide association study of Barley Yellow Dwarf Virus resistance in a Nested Association Mapping population of winter wheat using Skim Exome Capture and Practical Haplotype Graph imputation
Barley Yellow Dwarf Virus (BYDV) is a major constraint to wheat (Triticum aestivum L.) production, causing severe yield losses due to stunted growth, chlorosis, and reduced kernel weight. While chemical and cultural control strategies offer limited effectiveness, genetic resistance remains the most …

Effects of barley yellow dwarf virus and environment on grain avenanthramide concentration in spring oat (Avena sativa L.)
… This study explored the relationship between Barley Yellow Dwarf Virus (BYDV) and avenanthramide concentration, as well as the genotype-by-environment interaction and heritability for avenanthramide concentrations in Illinois. One hundred genotypes were evaluated for BYDV tolerance and AVN …

Barley Yellow Dwarf of Winter Wheat: Effects on Germplasm, and Inheritance, Combining Ability, and Reciprocal Effect for Tolerance to the Barley Yellow Dwarf Virus
Investigation of the effects of the barley yellow dwarf virus (BYDV) on winter wheat germplasm showed fall infection to be more devastating than spring infection, reducing grain yield an average of 61% vs. 38% for spring infection. BYDV also decreased winter survival, plant height, number of heads, …

The Effect of Within-host Virus Population Growth and Interspecific Competition on Aphid Transmission and Population Structure of Barley Yellow Dwarf Virus
Barley yellow dwarf virus (BYDV) (Luteoviridae) species PAV and PAS are ecologically similar in that they share aphid vectors and host species, but in agricultural fields in New York State we found that the prevalence of PAV was three times greater than that of PAS. To determine if differences in …

Aphid Transmission, Replication, and Transcription of BYDV -Pav -Il and Genome Organization of RhPV
… of an Illinois isolate of the PAV strain of Barley yellow dwarf virus (BYDV-PAV-IL), driven by Cauliflower mosaic virus-35S promoter (CaMV-35S), were constructed to study the mechanism of replication and transcription of BYDV-PAV-IL in oat protoplasts. Linearized wild-type and mutant cDNA …

Ecological and evolutionary aspects of interactions between microbes coinfecting plants
… fitness. In the research reported here, plant virus systems were used to explore the effects of coinfection on pathogen populations and host responses. Chapter 1 addresses the importance of coinfection timing using Barley yellow dwarf virus (BYDV-PAV) and Barley stripe mosaic virus. Coinfection …

Variation for root and shoot growth among wheat cultivars and the effects of barley yellow dwarf virus on growth
… in root growth, to evaluate the effects of barley yellow dwarf virus (BYDV) on root and shoot growth, and to study the effects of a plant growth regulator on root growth of healthy and BYDV infected plants. Cultivars evaluated were Caldwell, Cardinal, Clark, Howell, IL 87-2834, Tyler, and …

Crop loss in two spring oat cultivars due to Puccinia coronata f.sp. avenae and barley yellow dwarf virus, and a spring oat plant growth model
… (crown rust), in the presence or absence of barley yellow dwarf virus (BYDV-PAV-IL). Several levels of crown rust (CR) were established in all experiments by inoculation with CR or fungicide application. For experiments including BYDV, plots were infested with viruliferous aphids …

Evolutionary studies of wheat streak mosaic-associated viruses and characterization of the wheat virome
Wheat viruses including Wheat streak mosaic virus (WSMV), Triticum mosaic virus (TriMV), High Plains wheat mosaic emaravirus (HPWMoV), and Barley yellow dwarf virus (BYDV) cost substantial losses in crop yields annually. Although there have been extensive studies conducted on known wheat viruses, …

Effects of wheat streak mosaic virus and interactions with other cereal viruses on wheat
… of an Illinois isolate of wheat streak mosaic virus (WSMV) on yield of selected hard red spring wheat and soft red winter wheat cultivars were evaluated in three studies. In spring and fall of 1993 and 1994, twenty hard red spring wheat cultivars and fourteen soft winter wheat cultivars were …

Identification of quantitative trait loci and comparison of selection methods for barley yellow dwarf tolerance in spring oats and winter wheat
Barley yellow dwarf (BYD) is one of the most destructive diseases of cereal crops worldwide. Barley yellow dwarf viruses (BYDVs) are responsible for BYD and affect many cereals including wheat and oats. Symptoms depend on cultivar and environment, but normally include stunted growth, leaf …
