DNA markers in oat breeding for crown rust resistance (a review)

Труды по прикладной ботанике, генетике и селекции, 2022
Crown rust is the most harmful disease of oat (Avena sativa L.) around the world. The purpose of this review is to analyze and generalize the available information about DNA markers developed for oat breeding for resistance to crown rust.

Genomics Research on the Road of Studying Biology and Virulence of Cereal Rust Fungi. [PDF]

Mol Plant Pathol
We review advances in haplotype‐resolved genome analysis, virulence evolution and population structure of cereal rusts that reveal pathogen adaptation and epidemiology and outline emerging genomic strategies for future research. ABSTRACT Rust fungi are highly destructive pathogens that pose a significant threat to crop production worldwide, especially ...

Mapping of crown rust (Puccinia coronata f. sp. avenae) resistance gene Pc54 and a novel quantitative trait locus effective against powdery mildew (Blumeria graminis f. sp. avenae) in the oat (Avena sativa) line Pc54.

Phytopathology, 2022
The Pc54 oat line carries the crown rust resistance gene 'Pc54' and an unknown gene effective against powdery mildew. In this study two recombinant inbred line populations were developed to identify the genomic locations of the two genes and producing ...

Crown rust on oat genotypes with different levels of resistance: damages and losses [PDF]

Ciência Rural, 2021
: The evolution in virulence of Puccinia coronata f. sp. avenae has challenged the genetic resistance to crown rust in oat genotypes. New resistance sources are constantly required for yield stabilization and costs reduction.

Aecial and telial host specificity of Puccinia coronata var. coronata, a Eurasian crown rust fungus of two highly invasive wetland species in North America.

Plant Disease, 2023
The Eurasian crown rust fungus Puccinia coronata var. coronata (Pcc) was recently reported in North America and is widespread across the Midwest and Northeast United States. Pcc is a close relative of major pathogens of oats, barley, and turfgrasses.

Genetic diversity and specialisation of Eudarluca caricis on some graminaceous Puccinia species [PDF]

, 2015
Eudarluca caricis is a common hyperparasite of rusts. A total of 100 cultures were isolated from six Puccinia species or forms growing on 10 species of British grasses at two sites approximately 3 km apart.
