Pathogenicity and Metabolomic Characterization of Fusarium graminearum and Fusarium poae Challenge in Barley under Controlled Conditions

Journal of Fungi
Barley is the third most important cereal crop in terms of production in Canada, and Fusarium head blight (FHB) is one of the main fungal diseases of barley. FHB is caused by a species complex of Fusaria, of which Fusarium graminearum Schwabe is the main

Decoding MAPK cascades in plant immunity: Activation, regulation, integration, and pathogen manipulation

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 3000-3024, August 2026.
This review focuses on mitogen‐activated protein kinase (MAPK) activation and summarizes how plants regulate and integrate MAPK signaling in modulating plant immune responses. It also examines the effectors pathogens have evolved to manipulate MAPK activation and thereby inhibit plant immunity.

The Vacuolar Ca2+/H+ Exchanger AaVCX Regulates Calcium Homeostasis, the Differentiation of Infection Structures and Pathogenicity in Alternaria alternata Under the Transcriptional Control of AaCrz1

Molecular Plant Pathology, Volume 27, Issue 8, August 2026.
AaVCX, a vacuolar Ca2+/H+ exchanger regulated by AaCrz1, maintains calcium homeostasis. Its deletion elevates cytoplasmic Ca2+, disrupting signals essential for spore germination, appressorium formation and infection hyphae differentiation, thereby blocking infection structure differentiation and reducing pathogenicity in Alternaria alternata ...

Shifts in Fusarium Communities and Mycotoxins in Maize Residues, Soils, and Wheat Grains throughout the Wheat Cycle: Implications for Fusarium Head Blight Epidemiology

Microorganisms
Fusarium Head Blight (FHB), predominantly caused by Fusarium species, is a devastating cereal disease worldwide. While considerable research has focused on Fusarium communities in grains, less attention has been given to residues and soil, the primary ...

The Fungal Pathogen Fusarium graminearum Can Hydrolyse Tryptamine‐Derived Hydroxy‐Cinnamic Acid Amide Defence Compounds, and Generates Highly Increased Auxin Levels in Wheat via Copper Amine‐Oxidases

Molecular Plant Pathology, Volume 27, Issue 8, August 2026.
Fusarium graminearum can cleave tryptamine‐derived hydroxycinnamic acid amides and convert the released tryptamine into auxin, suppressing plant defence responses; aoxΔ7—septuple knockout of copper amine oxidases blocks auxin formation. ABSTRACT The important cereal pathogen Fusarium graminearum is not only able to produce trichothecene toxins, like ...

Comparison of the Fungistatic Activity of Selected Essential Oils Relative to Fusarium graminearum Isolates

Molecules, 2019
The aim of the study was to determine the chemical composition of lemon, rosewood, geranium and rosemary oils, and compare their effect on the sensitivity of Fusarium graminearum ZALF 24 and Fusarium graminearum ZALF 339 isolated from infected cereals ...

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 ...

Fusarium graminearum mycotoxins and their biosynthetic genes

Mycotoxins, 2012
The plant pathogenic fungus Fusarium graminearum (teleomorph: Gibberella zeae) is a crucial pathogen of major cereal crops and the fungus has taken on greater importance throughout the world. Taking advantage of rapid progress on fungal molecular techniques, we have studied biosynthetic pathways of harmful secondary metabolites of F.

The Mechanisms of Developing Fungicide Resistance in Fusarium graminearum Causing Fusarium Head Blight and Fungicide Resistance Management

Pathogens
Fusarium head blight (FHB), primarily caused by Fusarium graminearum, is one of the economically significant diseases in small grains. FHB causes severe damage to wheat production and grain quality.
