Identification of Resistant Sources to Crown Rust (Puccinia Coronata) in Oat [PDF]

مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2012
This study was conducted to search for new resistant sources to oat leaf rust as well as to characterize the macroscopic components of resistance to crown rust under controlled conditions. One hundred twenty different accessions of oats obtained from the

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 ...

Effect of Weather on the Occurrence of Puccinia Graminis Subsp. Graminicola and Puccinia Coronata F. Sp. Lolii at Lolium Perenne L. and Deschampsia Caespitosa (L.) P. B.

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
Monitoring of Puccinia graminis subsp. graminicola and Puccinia coronata f. sp. lolii was carried out in Plant breeding station called Větrov. The pathogens were estimated on turf grass (Lolium perenne L., Deschampsia caespitosa (L.) P.

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.

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 ...

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.

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.
