Genome-wide association study for crown rust (Puccinia coronata f. sp. avenae) and powdery mildew (Blumeria graminis f. sp. avenae) resistance in an oat (Avena sativa) collection of commercial varieties and landraces [PDF]
Diseases caused by crown rust (Puccinia coronata f. sp. avenae and powdery mildew (Blumeria graminis f. sp. avenae) are among the most important constraints for the oat crop.

Validation of reference genes as an internal control for studying Avena sativa–Puccinia coronata interaction by RT-qPCR [PDF]
In this study we evaluated eleven candidate reference genes in Avena sativa during compatible and incompatible interactions with two different pathotypes of Puccinia coronata f. sp. avenae in six time points post-inoculation.

Mapping and identification of molecular markers for the Pc96 gene conferring resistance to crown rust in oat. [PDF]
Oat crown rust caused by Puccinia coronata f. sp. avenae P. Syd. & Syd (Pca) is a major constraint to oat (Avena sativa L.) production in many parts of the globe.

Genome biology and evolution of mating-type loci in four cereal rust fungi. [PDF]
Permanent heterozygous loci, such as sex- or mating-compatibility regions, often display suppression of recombination and signals of genomic degeneration. In Basidiomycota, two distinct loci confer mating compatibility. These loci encode homeodomain (HD)

Identification of reference genes for gene expression assessment in Avena sativa under biotic stress triggered by Blumeria graminis [PDF]
A repeatable and reliable reverse transcription quantitative PCR (RT-qPCR) experiment depends upon proper reference genes (RGs) selection. This study aims to examine the expression stability of nine candidate RGs for the Avena sativa – Blumeria graminis ...

Uncovering the genetic basis of crown rust resistance in a northern-by-southern oat biparental population. [PDF]
Crown rust, caused by the fungal pathogen Puccinia coronata f. sp. avenae (Pca), is a destructive foliar disease of oat. Use of host resistance is the preferred method of disease management. However, frequent emergence of new Pca races has hindered crown

A high-resolution haplotype collection uncovers somatic hybridization, recombination and intercontinental movement in oat crown rust. [PDF]
The population structure and evolution of basidiomycetes like rust fungi are influenced by complex reproductive cycles and dikaryotic life stages where two independent nuclear haplotypes are present in the cell.

Increased virulence of Puccinia coronata f. sp.avenae populations through allele frequency changes at multiple putative Avr loci. [PDF]
Pathogen populations are expected to evolve virulence traits in response to resistance deployed in agricultural settings. However, few temporal datasets have been available to characterize this process at the population level.

GWAS and genomic prediction of crown rust resistance in the southern US elite oat (Avena sativa L.) germplasm [PDF]
Crown rust (CR), caused by Puccinia coronata f. sp. avenae, is a major constraint to oat (Avena sativa L.) production in the southern United States. We dissected the genetic architecture of CR resistance and assessed genomic prediction in 234 winter and ...
