DNA markers in oat breeding for crown rust resistance (a review) [PDF]

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.

Exogenous double-stranded RNA inhibits the infection physiology of rust fungi to reduce symptoms in planta. [PDF]

Mol Plant Pathol, 2023
Rust fungi (Pucciniales) are a diverse group of plant pathogens in natural and agricultural systems. They pose ongoing threats to the diversity of native flora and cause annual crop yield losses.

Identification of reference genes for gene expression assessment in Avena sativa under biotic stress triggered by Blumeria graminis [PDF]

Scientific Reports
A repeatable and reliable reverse transcription quantitative PCR (RT-qPCR) experiment depends upon proper reference genes (RGs) selection. This study aims to examine the expression stability of nine candidate RGs for the Avena sativa – Blumeria graminis ...

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)

A high-resolution haplotype collection uncovers somatic hybridization, recombination and intercontinental movement in oat crown rust. [PDF]

PLoS Genetics
The population structure and evolution of basidiomycetes like rust fungi are influenced by complex reproductive cycles and dikaryotic life stages where two independent nuclear haplotypes are present in the cell.

Fungicidas, doses e volumes de calda no controle químico da ferrugem da folha da aveia (Puccinia coronata f. sp. avenae) Fungicides, rates and spray volumes in the chemical control of oats crown rust (Puccinia coronata f. sp. avenae)

Engenharia Agrícola, 2007
A ferrugem da folha (Puccinia coronata f. sp. avenae) é a doença mais destrutiva da aveia, e aplicações de fungicidas com volumes baixos de calda podem reduzir a eficácia do controle químico.

Nuclear exchange generates population diversity in the wheat leaf rust pathogen Puccinia triticina. [PDF]

Nat Microbiol, 2023
In clonally reproducing dikaryotic rust fungi, non-sexual processes such as somatic nuclear exchange are postulated to play a role in diversity but have been difficult to detect due to the lack of genome resolution between the two haploid nuclei.

Mapping crown rust resistance in the oat diploid accession PI 258731 (Avena strigosa). [PDF]

PLoS ONE
Oat crown rust, caused by Puccinia coronata Corda f. sp. avenae Eriks. (Pca), is a major biotic impediment to global oat production. Crown rust resistance has been described in oat diploid species A.

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

Ciência 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
