Wheat Encodes Small, Secreted Proteins That Contribute to Resistance to Septoria Tritici Blotch

Frontiers in Genetics, 2020
During plant–pathogen interactions, pathogens secrete many rapidly evolving, small secreted proteins (SSPs) that can modify plant defense and permit pathogens to colonize plant tissue.

Sas3-mediated histone acetylation regulates effector gene activation in a fungal plant pathogen

mBio, 2023
Effector proteins are secreted by plant pathogens to enable host colonization. Typically, effector genes are tightly regulated, have very low expression levels in axenic conditions, and are strongly induced during host colonization.

Effects of salicylic acid on the growth and pathogenicity of Zymoseptoria tritici [PDF]

Biological Journal of Microorganism, 2018
Introduction: Zymoseptoria tritici, is a species of filamentous fungus and causes the widespread wheat disease Septoria tritici blotch (STB). Salicylic acid has a key role in plant defence reactions and is also involved in the induction of systemic ...

Determining frequencies of fungicide resistance in Leptosphaeria maculans that render demethylation inhibitor fungicides ineffective in the field

Pest Management Science, EarlyView.
As little as 1–10% of the population is needed to be resistant for demethylation inhibitor fungicides to be rendered ineffective. Following a single round of selection, the frequency increases by more than 15% with limited fitness penalty detected when no selection is present.

Analysis of small RNAs in the Zymoseptoria tritici – wheat interaction [PDF]

, 2019
Cross-kingdom small RNA (sRNA) silencing has recently emerged as a mechanism facilitating fungal colonisation and disease development in plants. Here we characterise RNAi pathways in Zymoseptoria tritici, a major fungal pathogen of wheat, and assess ...

Dose-dependent selection drives lineage replacement during the experimental evolution of SDHI fungicide resistance in Zymoseptoria tritici [PDF]

, 2017
Fungicide resistance is a constant threat to agricultural production worldwide. Molecular mechanisms of fungicide resistance have been studied extensively in the wheat pathogen Zymoseptoria tritici.

Plasticity of the MFS1 Promoter Leads to Multidrug Resistance in the Wheat Pathogen Zymoseptoria tritici

mSphere, 2017
The ascomycete Zymoseptoria tritici is the causal agent of Septoria leaf blotch on wheat. Disease control relies mainly on resistant wheat cultivars and on fungicide applications.

Discovery and characterisation of succinate dehydrogenase inhibitor resistance in Plenodomus biglobosus (phoma stem canker of oilseed rape)

Pest Management Science, EarlyView.
SDHI resistance is reported and characterised for the first time in the oilseed rape phoma stem canker pathogen Plenodomus biglobosus (Leptosphaeria biglobosa). We investigate cross‐resistance patterns, associated SDH target‐site mutations, possible fitness costs, and consider the implications for disease and resistance management.

Exploring the Genetic Regulation of Asexual Sporulation in Zymoseptoria tritici

Frontiers in Microbiology, 2018
Zymoseptoria tritici is the causal agent of septoria tritici blotch, a devastating fungal disease of wheat which can cause up to 40% yield loss. One of the ways in which Z. tritici spreads in the field is via rain splash-dispersed asexual pycnidiospores,

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
