A high-resolution haplotype collection uncovers somatic hybridization, recombination and intercontinental movement in oat crown rust. [PDF]
PLoS GeneticsThe 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.

Genome-wide markers for seed yield and disease resistance in perennial ryegrass
Crop Journal, 2022 The market success of perennial ryegrass (Lolium perenne L.) cultivars depends on sufficient seed production, as they are propagated by seed. However, breeding for high quality forage production reduces seed yield, and breaking the negative correlation ...

Virulence of Oat Crown Rust in Mexico [PDF]
Plant Disease, 2005 Virulence of isolates of Puccinia coronata collected during 1992 to 1998 from Sonora, Chihua-hua, Nuevo Leon, and five states in Central Mexico were compared on a set of 27 differential oat (Avena sativa) lines with different genes for race-specific resistance.

Virulence Associations in Oat Crown Rust [PDF]
Phytopathology®, 2005 Isolates of Puccinia coronata obtained from natural populations of Avena sterilis in Israel, winter oat (A. sativa) cultivars in Texas, and spring oat cultivars in the Northern Plains states of Minnesota, North Dakota, and South Dakota were analyzed for significance of pairwise virulence associations.

Sources and Genetics of Crown Rust Resistance in Barley [PDF]
Phytopathology®, 2002 Crown rust, caused by Puccinia coronata var. hordei, is a new disease threat to barley in the Great Plains region of the United States. Deployment of resistant cultivars is the only economically viable option for the control of this disease. Thus, the objective of this study was to investigate the sources and genetics of crown rust resistance in ...

Virulence of Oat Crown Rust in Brazil and Uruguay [PDF]
Plant Disease, 2005 Race-specific resistance to crown rust, the most important disease of oat (Avena sativa) in Bra-zil, often fails within a few years of use in Brazilian cultivars. Virulence of 144 isolates of Puccinia coronata from cultivated oat in Brazil in 1997 to 1999 and 36 isolates from Uruguay in 1994-95 and 1998 was tested on a set of 27 oat crown rust ...

Hidden Diversity of Crown Rust Resistance within Genebank Resources of Avena sterilis L.
Agronomy, 2021 The most widespread and damaging fungal disease of the oat plant is crown rust. Resistance to the crown rust pathogen, Puccinia coronata Cda. f. sp. avenae (Pca), at the seedling stage of Avena sterilis accessions from the Polish national genebank was ...
