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

The Plant Genome
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 ...

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.

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

Theor Appl Genet, 2022
AbstractCrown rust, caused byPuccinia coronataf. sp.avenae(Pca), is a significant impediment to global oat production. Some 98 alleles at 92 loci conferring resistance toPcainAvenahave been designated; however, allelic relationships and chromosomal locations of many of these are unknown.

Genome-Enabled Analysis of Population Dynamics and Virulence-Associated Loci in the Oat Crown Rust Fungus Puccinia coronata f. sp. avenae

Molecular Plant-Microbe Interactions, 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.

Anthraquinones and their analogues as potential biocontrol agents of rust and powdery mildew diseases of field crops. [PDF]

Pest Manag Sci, 2022
Biotrophic fungi as rust and powdery mildew can cause severe physiological damage in crops of agronomic importance. This article highlights the importance of some fungal anthraquinones and their analogues, especially pachybasin, which are very promising molecules with effective potential as safely biofungicide.

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.
