Quantitative resistance to Puccinia striiformis f. sp. hordei in barley near-isogenic (BISON) lines

Creator:: Richardson, Kelley L.
Abstract:: Quantitative resistance (QR) to disease is usually more durable than qualitative resistance, but its genetic basis is not well understood. We used the barley/barley stripe rust pathosystem as a model for the characterization of the QR phenotype and associated genomic regions. As an intermediate step in the preparation of near-isogenic...

DNA markers and characterization of novel sources of eastern filbert blight resistance in European hazelnut (Corylus avellana L.)

Creator:: Peterschmidt, Brooke C.
Abstract:: European hazelnut is a significant crop in the Pacific Northwest, and the US ranks 4th internationally for hazelnut production. Production in the Pacific Northwest is threatened, however, by the disease eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. To meet the challenges faced by the...

Characterization of the response mediated by the plant disease susceptibility gene LOV1

Creator:: Gilbert, Brian M.
Abstract:: Victoria blight, caused by fungus Cochliobolus victoriae, is a disease originally described on oats and recapitulated on Arabidopsis. Victoria blight is used as a model plant disease that conforms to an inverse gene-for-gene interaction. C. victoriae virulence is dependent upon its production of victorin, a host-specific toxin that induces programmed...

DNA markers linked to novel sources of resistance to eastern filbert blight in European hazelnut (Corylus avellana L.)

Creator:: Sathuvalli, Vidyasagar R.
Abstract:: The hundred-year history of the hazelnut industry in the Pacific Northwest is threatened by eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. Marker-assisted selection (MAS) has been extensively used for ‘Gasaway’ resistance in the hazelnut breeding program at Oregon State University. Concern over breakdown of...

Breeding for bruchid resistance in common bean (Phaseolus vulgaris L.) : interspecific introgression of lectin-like seed proteins from tepary bean (P. acutifolius A. Gray), genetic control and bruchid resistance characterization.

Creator:: Kusolwa, Paul Mbogo
Abstract:: Interspecific hybridization was initiated between wild P. acutifolius accession G40199 and P. vulgaris to introgress resistance to Acanthoscelides obtectus (bean seed weevil). F1 interspecific hybrids were recovered by embryo rescue and maintained until flowering. Mostly sterile hybrids were backcrossed twice to common bean cultivar ICA Pijao to recover sufficient fertility...

Phenotyping diverse strawberry (Fragaria spp.) germplasm for aid in marker- assisted breeding, and marker-trait association for red stele (Phytophthora fragariae) resistance marker Rpf1

Creator:: Mathey, Megan M.
Abstract:: Strawberry is one of four crops included in the USDA-NIFA Specialty Crop Research Initiative-funded RosBREED project along with apple, peach, and cherry. Phenotyping strawberry for specific horticultural and commercial traits is important to identify associations with genotypic marker(s). This process is the first step in translating genomic knowledge into enhanced...

Genetic dissection of Victoria blight disease susceptibility in Arabidopsis thaliana

Creator:: Sweat, Teresa A.
Abstract:: The fungus Cochliobolus victoriae causes Victoria blight of oats and Arabidopsis and is pathogenic due to its production of a compound called victorin, which induces programmed cell death in sensitive plants. Victorin sensitivity in Arabidopsis is conferred by the dominant gene LOCUS ORCHESTRATING VICTORIN EFFECTS1 (LOV1), which encodes a coiled-coil-nucleotide...

Silencing the Agrobacterium tumefaciens oncogenes

Creator:: Pitrak, Jennifer
Abstract:: Crown gall disease is an agricultural problem caused by the soil-borne bacterium, Agrobacterium tumefaciens. A. tumefaciens oncogenes cause transformed plant cells to overproduce the hormones, auxin and cytokinin. High hormone levels cause unorganized plant cell growth resulting in a gall. Control of crown gall disease is difficult because after plant...

Microsatellite Marker Development, Characterization and Mapping in European Hazelnut (Corylus avellana L.), and Investigation of Novel Sources of Eastern Filbert Blight Resistance in Corylus

Creator:: Bhattarai, Gehendra
Abstract:: European hazelnut, an important nut crop in Oregon agriculture, is threatened by the fungal disease eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller. The hazelnut breeding program at OSU has been working on development of EFB-resistant cultivars. DNA markers allow mapping of traits using segregating progenies and...

Multi-location analysis for the identification of quantitative trait loci underlying disease resistance against Cephalosporium gramineum and Puccinia striiformis f. sp. tritici by linkage mapping in wheat (Triticum aestivum L.)

Creator:: Vazquez, Maria Dolores
Abstract:: Wheat (Triticum aestivum L.) is one of the major crops produced in the U.S. Pacific Northwest, a region known for its wheat production for international export. Wheat production in the region is threatened by diseases such as Cephalosporium stripe and stripe rust. Cephalosporium stripe is a vascular wilt disease of...
