Early-detection surveillance for stem rust of wheat: insights from a global epidemic network based on airborne connectivity and host phenology

Environmental Research Letters, 2022
Stem rust of wheat, caused by the airborne pathogen Puccinia graminis , is a re-emerging crop disease representing a major concern to global food security. Potential long-distance transport by wind over a worldwide distributed host represents a challenge

Eine einfache und schnelle lichtmikroskopische Methode zur Identifizierung von Rostpilzen (Puccinia spp.) auf Weizen (Triticum aestivum) anhand von Keimporenmerkmalen der Urediniosporen

Journal für Kulturpflanzen, 2020
In Mitteleuropa sind auf Weizen (Triticum aestivum) drei Rostpilzarten (Pucciniales) bekannt, nämlich der Schwarzrost (Puccinia graminis), der Gelbrost (P. striiformis) und der Braunrost (P. triticina). Diese Arten sind ökonomisch bedeutend.

Long‐term surveillance reveals hybridization by nuclear reassortment and intercontinental spread as major evolutionary drivers in wheat yellow rust

New Phytologist, Volume 251, Issue 4, Page 2091-2106, August 2026.
Documented incursions of Puccinia striiformis 2009–2023 based on sequential resampling of MLGs/pathogen races on different continents. Summary Evolutionary forces affecting crop pathogens, including hybridization and long‐distance dispersal (LDD), may have strong implications for food security and sustainable plant disease control at global scales ...

A Meta‐Analysis Reveals That the Protective Role of Silicon in Grasses Against Fungal Pathogens Depends on Infection Mechanism

Plant, Cell &Environment, Volume 49, Issue 8, Page 5947-5964, August 2026.
ABSTRACT Pathogen infection drives plant community structure and constrains global agricultural productivity. Silicon (Si) improves resistance to abiotic and herbivory stress, particularly in grasses, but relatively little attention has addressed Si‐mediated resistance to pathogens, nor has it tested how this varies according to the type of plant and ...

Characterization of a Tryptophan 2-Monooxygenase Gene from Puccinia graminis f. sp. tritici Involved in Auxin Biosynthesis and Rust Pathogenicity

Molecular Plant-Microbe Interactions, 2014
The plant hormone indole-3-acetic acid (IAA) is best known as a regulator of plant growth and development but its production can also affect plant–microbe interactions.

From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance

Advanced Science, Volume 13, Issue 39, 13 July 2026.
Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...

The integrated concept of disease resistance; a new view including horizontal and vertical resistance in plants [PDF]

, 1977
Horizontal, uniform, race-non-specific or stable resistance can be discerned according to Van der Plank, from vertical, differential, race-specific or unstable resistance by a test in which a number of host genotypes (cultivars or clones) are tested ...

Rust resistance in barley accessions County and BHS248

Crop Science, Volume 66, Issue 4, July/August 2026.
Abstract Rusts can cause devastating losses of barley (Hordeum vulgare L.) in epidemic years. Several reactions to Puccinia hordei (Rph) genes/quantitative trait loci (QTLs) for resistance to barley leaf rust (BLR) have been documented. In contrast, there is a dearth of characterized resistance sources against stem rust (SR) caused by Puccinia graminis.
