Genetic Differentiation in the SdhC Subunit Confers Intrinsic Resistance to SDHI Fungicides in Fusarium asiaticum

Molecular Plant Pathology, Volume 27, Issue 5, May 2026.
In Fusarium asiaticum, two homologous SdhC subunits (FaSdhC1/C2) regulate sensitivity to SDHI fungicides: deletion of FaSDHC1 decreases sensitivity, while deletion of FaSDHC2 increases it. Multiple mutations in ΔFaSDHC2 confer resistance to SDHI fungicides.

Aerobic De-Epoxydation of Trichothecene Mycotoxins by a Soil Bacterial Consortium Isolated Using In Situ Soil Enrichment

Toxins, 2016
Globally, the trichothecene mycotoxins deoxynivalenol (DON) and nivalenol (NIV) are among the most widely distributed mycotoxins that contaminate small grain cereals. In this study, a bacterial consortium, PGC-3, with de-epoxydation activity was isolated

Weather‐Driven Ensemble Logistic Models for Predicting Fusarium Head Blight of Wheat in Brazil

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Functional data analysis identified key post‐flowering weather variables influencing Fusarium head blight (FHB) epidemics in southern Brazil. Logistic and ensemble models integrating these predictors achieved high discrimination (AUC ≤ 0.84). Economic evaluation showed fungicide use was profitable (NMB > 80%) above 0.45 risk probability, supporting ...

Chemistry and Interconversion of Complex Trichothecenes [PDF]

, 1987
The trichothecenes are a ubiquitous group of toxic fungal sesquiterpenoids. Previous studies have shown that the 12,13-epoxide present in the trichothecenes may be crucial for biological activity.

Population Structure and Genomic Diversity of Fusarium poae Associated With Barley and Oat in Canada

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Population genomics of Fusarium poae from Canadian barley and oat revealed high genetic diversity, weak geographic structure and a hierarchical population comprising two major groups. A distinct, low‐diversity lineage (Group IIa) with elevated linkage disequilibrium suggests recent emergence driven by clonal expansion or selective sweep.

Aflatoxin B1, B2, G1, G2, Zearalenone, and Ochratoxin A in Cereals, Cereal‐Based Products and Baby Food: Method Validation, Monitoring Study and Exposure Assessment of the Italian Population

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
A validated HPLC‐FLD analytical method for the determination of aflatoxins, zearalenone, and ochratoxin A in cereals was applied to the analysis of 402 samples collected in Italy from 2013 to 2023 and to perform a risk assessment evaluation for the Italian population. Prevalence of contaminated samples was generally low and restricted to maize samples.

Multitoxin analysis of trichothecenes, including NX toxins, in rice and wheat

Applied Food Research
Fusarium species biosynthesize trichothecenes that contaminate food and poses health risks. Among these, NX toxins produced by F. graminearum and F. culmorum, are structurally similar to deoxynivalenol (DON).

Occurrence of mycotoxins in milk and dairy products in Brazil: A review of recent data, regulatory aspects, preventive and decontamination strategies

International Journal of Dairy Technology, Volume 79, Issue 2, April–June 2026.
Mycotoxin data in Brazilian milk and dairy products over 20 years indicate aflatoxin M1 as the most frequent, although ochratoxin A, fumonisins and deoxynivalenol were also found in some studies. These data underscore the importance of control measures to reduce dietary mycotoxins in Brazilian dairy feed and avoid their residues in milk.

Methods for the Detection of Trichothecenes

Journal of AOAC INTERNATIONAL, 1975
Abstract The trichothecenes are a group of fungal metabolites with a tetracyclic, sesquiterpenoid ring system and include a number of compounds which are highly toxic. These compounds are produced by various species of the imperfect fungi including members of the following genera: Calonectria, Fusarium, Myrothecium, Stachybotrys ...

The complexation properties of some unnatural and natural macrocyclic trichothecenes

, 1988
As a result of investigating the complexing properties of a series of novel polyether analogues (3)-(9) of macrocyclic trichothecenes towards alkali metal cations and RNH3+ ions, it has been proposed, with supporting evidence from X-ray crystallography ...
