Detection of race-specific resistance against Puccinia coronata f. sp. avenae in Brachypodium species [PDF]

open access: yesPhytopathology®, 2018
Abstract Oat crown rust caused by Puccinia coronata f. sp. avenae is the most destructive foliar disease of cultivated oat. Characterization of genetic factors controlling resistance responses to Puccinia coronata

Mapping crown rust resistance at multiple time points in elite oat germplasm

open access: yesThe Plant Genome, Volume 13, Issue 1, March 2020., 2020
Abstract Crown rust, caused by Puccinia coronata f. sp. avenae Erikss., is the most important disease impacting cultivated oat (Avena sativa L.). Genetic resistance is the most desirable management strategy. The genetic architecture of crown rust resistance is not fully understood, and previous mapping investigations have mostly ignored temporal ...

Herança da resistência à ferrugem da folha da aveia (Puccinia coronata f. sp. avenae Fraser & Led.) em genótipos brasileiros de aveia branca Inheritance of oat leaf rust (Puccinia coronata f. sp. avenae Fraser & Led.) resistance in white oat brazilian genotypes

open access: yesCiência Rural, 2006
A ferrugem da folha da aveia é a moléstia mais importante que ataca a cultura da aveia, ocorrendo em praticamente todas as áreas em que a aveia é cultivada. A forma mais indicada para o seu controle é a utilização de cultivares resistentes. Contudo, para

Induction of Avenanthramides in Oat Leaves Inoculated with Crown Rust Fungus,Puccinia coronataf. sp.avenae [PDF]

open access: yesBioscience, Biotechnology, and Biochemistry, 1995
The chemical structures of the metabolites induced in oat leaves that had been inoculated with an incompatible race of crown rust fungus (phytoalexins) were examined. An HPLC analysis, using synthetic standards, demonstrates that they were a series of N-acyl 5-hydroxyanthranilates named avenanthramides, where the acyl groups were p-coumaroyl ...

Apoptotic Cell Death is a Common Response to Pathogen Attack in Oats

open access: yesMolecular Plant-Microbe Interactions, 2002
We have examined the characteristics of cell death induced by pathogen infection in oats with respect to following hallmark apoptotic features: DNA laddering, chromatin condensation, and electron microscopic-bterminal deoxynucleotidyl transferase ...

Axenic culture of two rust fungi, Puccinia coronata f. sp. avenae and P. recondita f. sp. tritici.

open access: yesJapanese Journal of Phytopathology, 1978
Urediniospores of Puccinia coronata f. sp. avenae race 367 and P. recondite f. sp. tritici race 45 were respectively cultured on an artificial medium. Urediniospores free of contaminating microorganisms were obtained by aseptic leaf culture. After the urediniospores were separately seeded on the medium, both rust fungi grew well and then formed white ...

Genetic progress from 15 years of white oat breeding in Brazil

open access: yesCrop Science, Volume 66, Issue 3, May/June 2026.
Abstract Despite advances in crop management and breeding, cereals still face considerable yield losses from phytopathogens and lodging caused by adverse weather. Developing oat genotypes that combine disease tolerance, lodging resistance, and industrial quality is therefore essential, and the estimation of genetic progress allows validation of ...

Prevalence and Diversity of Fusarium Species in Oat Grains Harvested From Commercial Oat Fields in Ireland in 2022

open access: yesPlant Pathology, Volume 74, Issue 9, Page 2818-2829, December 2025.
From 4140 isolates in 44 Irish oat fields, morphology, rDNA internal transcribed spacer (ITS) and TEF1‐α identified 8 Fusarium species. F. langsethiae predominated; F. tricinctum and F. poae were common, supporting surveillance. ABSTRACT This study investigated the prevalence and diversity of Fusarium species infecting Irish winter and spring oat ...

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

open access: yesPlant 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)

Identification of diagnostic kompetitive allele‐specific PCR markers for selection of crown rust resistance in oats

open access: yesCrop Science, Volume 65, Issue 3, May/June 2025.
Abstract Crown rust disease, caused by Puccinia coronata f. sp. avenae, poses a significant threat to global oat (Avena sativa L.) production. Molecular markers are essential to assist in the integration of multiple resistance genes into a single oat cultivar to achieve genetic resistance durability.
