The enemy of my enemy: concomitant impacts of goat browsing on native vegetation during invasive plant control

Restoration Ecology, Volume 34, Issue 4, May 2026.
The goal of invasive plant management is often to benefit native plants; however, the consequences of invasive plant management on native plants are not often assessed. While this is true generally for invasive plant management, it is particularly true for targeted grazing using livestock, such as goats, which is a rapidly expanding but little‐studied ...

Crown rust pathotypes determined on oats in the Czech Republic from 2004 to 2006 and reaction to oat cultivars

Czech Journal of Genetics and Plant Breeding, 2008
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.

Differential Infection and Colonisation of Needle Age Classes by Cronartium ribicola

Forest Pathology, Volume 56, Issue 1, February 2026.
ABSTRACT White pine blister rust (WPBR) is a disease on North American five‐needle white pine trees caused by the non‐native fungal pathogen Cronartium ribicola that is causing widespread decline and mortality of Pinus flexilis (limber pine) in high elevation western forests.

Plant defense strategies: The dual armor of disease resistance and tolerance

New Plant Protection, Volume 2, Issue 4, December 2025.
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.

Efektywność genów odporności na rdzę koronową u owsa zwyczajnego w stosunku do patotypów Puccinia coronata występujących w centralnej i południowo-wschodniej Polsce w latach 2010-2011

Agronomy Science, 2015
Rdza koronowa, powodowana przez grzyb Puccinia coronata, jest jedną z najpowszechniej występujących chorób grzybowych owsa w Polsce. Do tej pory u owsa zidentyfikowano ponad 100 genów odporności na ten patogen, jednak są one szybko przełamywane przez ...

Genomic Prediction and Genotype-by-Environment Interaction Analysis of Crown and Stem Rust in Ryegrasses in European Multi-Site Trials

Agronomy, 2021
Climate change calls for novel approaches to include environmental effects in future breeding programs for forage crops. A set of ryegrasses (Lolium) varieties was evaluated in multiple European environments for crown rust (Puccinia coronata f. sp. lolii)

Evaluating pasture forage plant breeding achievements: a review

New Zealand Journal of Agricultural Research, Volume 68, Issue 6, Page 1146-1220, December 2025.
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.

Prevalence and Diversity of Fusarium Species in Oat Grains Harvested From Commercial Oat Fields in Ireland in 2022

Plant Pathology, Volume 74, Issue 9, Page 2818-2829, December 2025.
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 ...

Carotenoid pigments of the spores of Puccinia coronata and Stereostratum corticioides

Japanese Journal of Phytopathology, 1961
Some qualitative and quantitative studies of the carotenoid pigments were made with uredospores of Puccinia coronata Corda, uredospores and teleutospores of Stereostratum corticioides (Berk. et Br.) Magnus. The major pigment of all samples is γ-carotene, constituting about 60per cent of total carotenoids, and β-carotene comes next excepting uredospores

Long‐Term Studies of Puccinia coronata f. sp. avenae in Australia Reveal High Pathogenic Diversity, Regional Virulence Differences, Evidence of Clonality and Rapid Emergence of Virulence Matching Deployed Host Resistance

Plant Pathology, Volume 74, Issue 6, Page 1778-1795, August 2025.
Australia‐wide studies of the oat crown rust pathogen in 1998–2023 found emergence of virulence to resistance genes after their deployment and changes in populations from 2011 due to the emergence of pathotypes with virulence for Pc64. ABSTRACT Long‐term, detailed Australia‐wide studies of pathogenic variability in Puccinia coronata f. sp. avenae (Pca)
