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

Characteristics of Resistance to Puccinia coronata f. sp. avenae in Avena fatua [PDF]
Plant Disease, 2018 Crown rust, caused by Puccinia coronata f. sp. avenae, is the most widespread and harmful fungal disease of oat. The best defense against the pathogen is use of cultivars with genetic resistance, which is effective, economic, and an environmentally friendly alternative to chemical control.

A North American System of Nomenclature for Puccinia coronata f. sp. avenae [PDF]
Plant Disease, 2000 A nomenclature system for designating virulence phenotypes of Puccinia coronata f. sp. avenae, the causal agent of oat crown rust, is proposed. Sixteen single gene oat (Avena sativa) lines, with seedling resistance genes Pc38, 39, 40, 45, 46, 48, 50, 51, 52, 54, 56, 58, 59, 62, 64, and 68, are the primary differentials.

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 ...

A Quantitative Assay of Puccinia coronata f. sp. avenae DNA in Avena sativa [PDF]
Plant Disease, 2006 Crown rust, caused by Puccinia coronata f. sp. avenae, is the most damaging disease of oat. Quantification of the disease can be done by visual or digital assessments of diseased leaf area, lesion number, lesion size, and latent period. Laborious measurements of sporulation can also be made. As an alternative to these methods, a new quantitative assay

Preliminary screening of Avena sterilis L. for resistance to crown rust
Agronomy Science, 2020 The best source of crown rust resistance genes (Pc) in genus Avena is a wild hexaploid A. sterilis L. In this study, accessions of A. sterilis gathered from European and North American gene banks, originated from 21 countries were evaluated at the ...

Resistance to Puccinia coronata f. sp. avenae in Avena magna, A. murphyi, and A. insularis [PDF]
Plant Disease, 2016 Wild oat tetraploids of the section Pachycarpa have already been proven to be a rich source of useful genes but have largely been unexploited for Puccinia coronata resistance. In this study, accessions of Avena magna, A. murphyi, and A. insularis gathered from European and North American gene banks were evaluated at the seedling stage for crown rust ...

Mega‐environment analysis and breeding for specific adaptation
Crop Science, Volume 63, Issue 2, Page 480-494, March/April 2023., 2023 Abstract Mega‐environment (ME) analysis is analysis of multi‐year, multi‐location crop variety trial data conducted in a target region of a crop to understand the magnitude and nature of genotype‐by‐environment interaction (GE) of the crop in the region. If repeatable GE patterns are identified, then the target region must be divided into subregions or
