Characterization Of A Novel Effector From Blumeria Graminis F. Sp. Hordei That Suppress Host Cell Death
… vulgare L., with the powdery mildew fungus, Blumeria graminis f. sp. hordei, is a well-developed model to investigate resistance and susceptibility to obligate biotrophic pathogens. The 130-Mb Blumeria genome encodes ca. 540 predicted effectors, which are hypothesized to suppress or induce …

Identification and analysis of mechanisms involved in a broad-spectrum disease resistant mutant of the winter wheat cv. Guardian
… broad-spectrum resistance to powdery mildew (Blumeria graminis f. sp. tritici), yellow rust (Puccinia striiformis f. sp. tritici), and leaf rust (Puccinia recondita f. sp. tritici), along with partial resistance to stagnonospora nodorum blotch (caused by the necrotroph Stagonosporum nodorum) …

Validation of Loci Conferring Adult Plant Resistance to Powdery Mildew in Wheat Cultivar Massey and Identification of Diagnostic Molecular Markers
Powdery mildew, caused by the pathogen Blumeria graminis (DC) Speer (Syn. Erysiphe graminis DC) f. sp. tritici, is a major disease of wheat (Triticum aestivum L.). Race-specific resistance is easily identified in the field due to its qualitative phenotype and it is easy to incorporate because it is …

Yield Improvement in Eastern Soft Red Winter Wheat from 1919 to 2009
… triticina f. sp. tritici) and powdery mildew [Blumeria graminis (DC.) E.O. Speer f. sp. tritici Em. Marchal] on grain yield components and agronomic traits. Replicated yield trials were grown at Warsaw, VA in 2010 and 2011, and at Holland and Blacksburg, VA in 2011. For objective 1, the genetic …

Inheritance of powdery mildew resistance genes in 10 winter wheat lines
… populations were inoculated with isolate 127 of Blumeria graminis (DC.) E. 0. Speer f. sp. tritici Em. Marchal in the greenhouse and evaluated for powdery mildew reaction; 2) the ten lines were crossed with each other and to each of 13 host differential lines with known genes for powdery mildew …

Responses of wheat to infection by Mycosphaerella graminicola
… to infection with M. graminicola were studied. Blumeria graminis f. sp. tritici causes powdery mildew disease of wheat. A method for dual inoculation of wheat with both M. graminicola and mildew was developed. Leaves preinoculated with virulent M. graminicola and subsequently inoculated with a …

Iron and reactive oxygen in wheat-pathogen interactions
… during attack by the powdery mildew fungus Blumeria graminis f.sp. tritici. This iron accumulates at cell wall appositions synthesised de novo beneath sites of pathogen attack. I further show, using histochemistry and pharmaceutical inhibitors, that this apoplastic iron accumulation is …

Characterization of Hulled and Hulless Winter Barley, Hordeum vulgare L., Through Traditional Breeding and Molecular Techniques
… hordei G. Otth), powdery mildew [caused by Blumeria graminis (DC.) E.O. Speer f. sp. hordei Em. Marchal], net blotch (caused by Pyrenophora teres) and spot blotch [caused by Cochliobolus sativus (Ito & Kuribayashi) Drechsler ex Dastur] will greatly aid in breeding for improved resistance. …

Improving barley for biofuel production – efficient transformation for lignin manipulation
… not decrease the resistance to the biotrophic Blumeria graminis and to the hemibiotrophic Rhynchosporium commune pathogens. The modified cell walls in the HvCAD2 RNAi lines had moderately improved sugar release for biofuel production. This study proves that it is possible to down-regulate CAD …

Validation, Saturation, and Marker-Assisted Selection of Quantitative Trait Loci Conferring Adult Plant Resistance to Powdery Mildew in an Elite Wheat Breeding Population
Powdery mildew caused by <i>Blumeria graminis</i> f. sp. <i>tritici</i> is one of the most devastating diseases in wheat (<i>Triticum aestivum</i>) worldwide. Hypersensitive, race specific genes primarily have been deployed to control the disease, however recent efforts have shifted to breeding for …

Molecular marker analysis of adult plant resistance to powdery mildew in common wheat
Powdery mildew, caused by Blumeria graminis (DC.) E.O. Speer f. sp. tritici E'm. Marchal (syn. Erysiphe graminis f. sp. tritici), is one of the major diseases of wheat (Triticum aestivum L.) worldwide. The use of cultivars with resistance to powdery mildew is an efficient, economical and …

Potential of Hulless Winter Barley as an Improved Feed Crop
… and to a composite population of powdery mildew (Blumeria graminis f. sp. hordei). These accessions also were planted in observation rows to evaluate heading date, plant height, lodging, and seed threshability. The hulless lines yielded 23% less, but had 13% higher test weights than the hulled …
