GWAS and genomic prediction of crown rust resistance in the southern US elite oat (Avena sativa L.) germplasm. [PDF]

Plant Genome
Abstract Crown rust (CR), caused by Puccinia coronata f. sp. avenae, is a major constraint to oat (Avena sativa L.) production in the southern United States. We dissected the genetic architecture of CR resistance and assessed genomic prediction in 234 winter and facultative oat lines adapted to the southern United States.

Biosurveillance of Invasive Southern Corn Rust: Insights Into Recent Migration Patterns and Virulence Variation. [PDF]

Mol Plant Pathol
Historical dispersal of Puccinia polysora and its phylogenetic differentiation and variation dynamics in the complementary epidemic centre of East and Southeast Asia. ABSTRACT Emerging pathogen races spreading via long‐distance migration increasingly threaten global agricultural ecosystems. Understanding how pathogens migrate and adapt to new hosts via

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.

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.

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.

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 ...

Microscopical observations of Sphaerellopsis filum, a parasite of Puccinia recondita

Acta Agrobotanica, 2012
Sphaerellopsis filum is a well-known parasite associated with many species of rust fungi. It is of frequent occurrence as parasite of cereal rusts: Puccinia recondita, P. coronata, P. graminis, P. hordei and P. striiformis.
