Plant defense strategies: The dual armor of disease resistance and tolerance
Plants employ dual strategies against pathogens: Resistance limits invasion via immune responses, whereas tolerance mitigates damage to sustain growth—together enhancing survival under infections. Abstract Pathogen infections pose a significant threat to plant health, global food security, and ecosystems.

Evaluating pasture forage plant breeding achievements: a review
ABSTRACT Forage plant breeding aims to deliver cultivars that increase on‐farm productivity through improved seasonal and annual yield, persistence of yield in perennials, and nutritive and feeding value. Breeding is generally undertaken in highly controlled field trials with individual plants or rows.

From 4140 isolates in 44 Irish oat fields, morphology, rDNA internal transcribed spacer (ITS) and TEF1‐α identified 8 Fusarium species. F. langsethiae predominated; F. tricinctum and F. poae were common, supporting surveillance. ABSTRACT This study investigated the prevalence and diversity of Fusarium species infecting Irish winter and spring oat ...

Crown rust, caused by Puccinia coronata var. avenae f. sp. avenae (Urban & Marková) (Pca), is an economically significant problem in oat in Canada. The growing of crown rust resistant oat cultivars has been an important management practice.

The incidence of oat crown rust (Puccinia coronata var. avenae Fraser et Ledingham) pathotypes was recorded in the Czech Republic in 2004-2006. The virulence of collected 79 monopustule oat crown rust isolates was assessed on 23 differentials.

Isolation and fine mapping of Rps6: An intermediate host resistance gene in barley to wheat stripe rust [PDF]
A plant may be considered a nonhost of a pathogen if all known genotypes of a plant species are resistant to all known isolates of a pathogen species. However, if a small number of genotypes are susceptible to some known isolates of a pathogen species ...

Self-inhibition in the uredospore germination of Puccinia coronata
Some inconsistent results from germination studies of rust spores have been recently explained on the basis of self-inhibitors. The present study was performed to make clear the self-inhibition in the uredospore germination of Puccinia coronata Corda. The samples of spores were harvested by shaking the rusted leaves which had been collected from field ...
