Differences in competitive ability among races of Colletotrichum graminicola in mixtures [PDF]

, 2018
Mixtures of races of Colletotrichum graminicola, causing sorghum (Sorghum bicolor) anthracnose and differing in their virulence range, were inoculated for five and six generations on the susceptible sorghum cultivar BR009 (Tx623), in two experiments in a

Mapping of crown rust resistance gene Pc53 in oat (Avena sativa).

PLoS ONE, 2018
Crown rust disease caused by the fungus Puccinia coronata f. sp. avenae (Pca) is a major production constraint of oat in North America, Europe, and Australia.

Population structure and genotype-phenotype associations in a collection of oat landraces and historic cultivars

Frontiers in Plant Science, 2016
Population structure and genetic architecture of phenotypic traits in oat (Avena sativa L.) remain relatively under-researched compared to other small grain species.

Expressão da resistência parcial à ferrugem da folha da aveia presente na linhagem MN841801, no ambiente do Sul do Brasil Expression of partial resistance to oat crown rust present in the lineage MN841801 submitted to the South Brazilian environment

Ciência Rural, 2009
A ferrugem da folha é a doença mais importante da aveia, podendo comprometer a qualidade e o rendimento de grãos em até 50%. No ambiente do Sul do Brasil, a maioria dos genes de resistência ao patógeno causador da doença tem baixa efetividade, e a ...

Puccinia coronata var. hordei var. nov. morphology and pathogenicity [PDF]

, 1999
A new variety of Puccinia coronata causing a disease on barley and other gramineous species is described. The fungus is different from other reported forms of P coronata in both morphology and pathogenicity.

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 ...

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
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.

Genetic analysis and dissection of crown rust resistance in diploid Avena [PDF]

, 1999
Disease resistance genes provide an effective way to prevent disease. They confer resistance specificity to a variety of plant pathogens, however, they share conserved mechanisms of pathogen recognition and resistance induction.

Virulence Structure and Diversity of Puccinia coronata f. sp. avenae P. Syd. & Syd. in Poland During 2013 to 2015 [PDF]

Plant Disease, 2019
The crown rust fungus Puccinia coronata f. sp. avenae P. Syd. & Syd. (Pca) attacks cultivated oat and its wild relatives, causing significant losses to the crop worldwide. Although understanding the origin and dynamics of the pathogen’s diversity is critical to developing methods for its control, there are little relevant data on Pca virulence ...
