Long‐Term Studies of Puccinia coronata f. sp. avenae in Australia Reveal High Pathogenic Diversity, Regional Virulence Differences, Evidence of Clonality and Rapid Emergence of Virulence Matching Deployed Host Resistance

Plant Pathology, Volume 74, Issue 6, Page 1778-1795, August 2025.
Australia‐wide studies of the oat crown rust pathogen in 1998–2023 found emergence of virulence to resistance genes after their deployment and changes in populations from 2011 due to the emergence of pathotypes with virulence for Pc64. ABSTRACT Long‐term, detailed Australia‐wide studies of pathogenic variability in Puccinia coronata f. sp. avenae (Pca)

Yulaf Taçlı Pası Hastalığı (Puccinia coronata f. sp. avenae)

Ziraat Mühendisliği, 2020
Kültürü yapılan yulaf (Avena sativa L. ve Avena byzantina Coch.), insan ve hayvan beslemesinde kullanılmakta ve mısır, buğday, arpa, çeltik ve darıdan sonra Dünya’da en çok üretimi yapılan tahıl bitkisidir. Yulaf taçlı pası (Puccinia coronata f. sp. avenae) yulafın en yaygın ve zarar verici hastalığıdır.

Breeding oat for resistance to the crown rust pathogen Puccinia coronata f. sp. avenae: achievements and prospects. [PDF]

Theor Appl Genet, 2022
Crown rust, caused by Puccinia coronata f. sp. avenae (Pca), is a significant impediment to global oat production. Some 98 alleles at 92 loci conferring resistance to Pca in Avena have been designated; however, allelic relationships and chromosomal ...

Genome biology and evolution of mating-type loci in four cereal rust fungi. [PDF]

PLoS Genetics
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)

Diversity of oat crown rust (Puccinia coronata f.sp. avenae) isolates detected by virulence and AFLP analyses

Plant Protection Science, 2010
Forty Puccinia coronata f.sp. avenae isolates from several European countries and Israel were tested for virulence to 18 differential oat lines. Amplified Fragment Length Polymorphism (AFLP) analysis was used to evaluate diversity among the studied ...

Genetic dissection of crown rust resistance in oat and the identification of key adult plant resistance genes. [PDF]

Plant Genome
Abstract Crown rust (Puccinia coronata f. sp. Avenae Erikss.) poses a significant threat to oat production worldwide. The most effective strategy for managing this disease involves identifying, mapping, and deploying resistance genes to develop cultivars with enhanced resistance.

Genome-enabled analysis of population dynamics and virulence associated loci in the oat crown rust fungus Puccinia coronata f. sp. avenae

bioRxiv, 2023
Puccinia coronata f. sp. avenae (Pca) is an important fungal pathogen causing crown rust that impacts oat production worldwide. Genetic resistance for crop protection against Pca is often overcome by the rapid virulence evolution of the pathogen.
