Marker development, genome mapping, and cloning of candidate disease resistance genes in sunflower, Helianthus annuus L

Creator:

Gedil, Melaku Ayele

Abstract:

The level of polymorphisms of many biochemical and DNA markers are low in cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA markers is limited. Molecular markers have not been developed for the most important diseases of sunflower, such as downy mildew. The objectives of this study were...

Mapping and introgression of disease resistance genes in barley (Hordeum vulgare L.)

Creator:

Toojinda, Theeryut

Abstract:

Molecular tools, coupled with unique germplasm stocks and rigorous phenotyping, are useful for developing a better understanding of qualitative and quantitative disease resistance genes in plants. The identification of molecular markers linked to all types of resistance genes provides opportunities for implementing a range of resistance breeding strategies, ranging from...

Genetic engineering of disease resistance in poplar : effects of bacterio-opsin over-expression and analysis of a copper-based system for resistance-gene activation

Creator:

Mohamed, Rozi

Abstract:

We tested a synthetic bacterio-opsin (bO) gene derived from Halobacterium halobium for its effect on disease resistance in transgenic poplar hybrids, and assessed a genetic system for controlling expression of this gene. In tobacco the bO gene caused necrotic lesions similar to an induced hypersensitive response (HR), increased levels of...

Stripe rust resistance pyramids in barley

Creator:

Castro Tabo, Ariel Julio

Abstract:

Genetic resistance is the most appropriate way to control diseases in crop plants. Resistance can be described as qualitative (involving a gene-for-gene system) or quantitative (with continuous distribution of disease levels). The relationships between different types of resistance remain obscure, as does the genetics of quantitative traits. The use of...

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...

Possible association between dwarfing genes Rht₁ and Rht₂ and the reaction to Septoria tritici blotch in winter wheat (Triticum aestivum L. em Thell)

Creator:

Baltazar, Baltazar

Abstract:

Four isogenic lines possessing different combinations of height reducing genes Rht₁ and Rht₂ from 'Norin 10' were crossed to a short stature, early maturing, septoria susceptible cultivar identified as the 'Tibet Dwarf'. The isogenic lines originated from the backcross population of 'Itana'/3/'Norin 10'/'Brevor 14'//6*'Itana'. Parents, F₁ and F₂ generations provided...

Genetic variability in the eastern filbert blight pathosystem

Creator:

Osterbauer, Nancy K.

Abstract:

The heritability of resistance to eastern filbert blight, caused by Anisogramma anomala, in European hazelnut (Corylus avellana) was evaluated in the progeny of seven cultivars crossed in 12 combinations. Progeny produced by crossing 'VR6-28' with three susceptible cultivars segregated 1:1 for complete resistance to eastern filbert blight. Histograms of disease...
