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.

Tetraopes Milkweed Beetle Genomes Elucidate the Adaptive Basis of a Temperate Coevolutionary Radiation

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...

Molecular Characterization and Expression Analysis of a Gene Encoding 3-Hydroxy-3-Methylglutaryl-CoA Reductase (HMGR) from Bipolaris eleusines, an Ophiobolin A-Producing Fungus

Journal of Fungi
Ophibolin A, a fungal sesterterpene, exerts a pivotal influence in a diverse array of biological processes, encompassing herbicidal, bactericidal, fungicidal, and cytotoxic activities.

Quiescence of postharvest pathogens: a fungal inhibition process or an immune response of the unripe host fruit?

New Phytologist, Volume 250, Issue 2, Page 812-821, April 2026.
Summary Postharvest pathogens can infect fresh produce both before and after harvest, by direct or wound‐enhanced penetration, remaining quiescent until ripening. Biotrophic‐like postharvest pathogens persist beneath host cells and can remain in a state of quiescence.

Main Ustilaginoidins and Their Distribution in Rice False Smut Balls

Toxins, 2015
Rice false smut has become an increasingly serious fungal disease in rice (Oryza sativa L.) production worldwide. Ustilaginoidins are bis-naphtho-γ-pyrone mycotoxins previously isolated from the rice false smut balls (FSBs) infected by the pathogen ...

Phytochemical and Biological Evaluation of Leaves, Stems, and Roots of Schinus weinmanniifolia Mart. Ex Engl.

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
Ethanolic extracts from leaves, stems, and roots of Schinus weinmanniifolia Mart. ex Engl. were evaluated for phytochemical composition and biological activities. The extracts exhibited antioxidant, photoprotective, and antimicrobial activity, without hemolytic effects or cytotoxicity at active concentrations. Syringic acid, epicatechin, and rutin were

Modes of Action of Microbially-Produced Phytotoxins

Toxins, 2011
Some of the most potent phytotoxins are synthesized by microbes. A few of these share molecular target sites with some synthetic herbicides, but many microbial toxins have unique target sites with potential for exploitation by the herbicide industry ...

Mating‐Type Loci Modulate Pathogenicity and Non‐Sexual Development Through Autocrine Pheromone Signalling in the Asexual Fungus Fusarium oxysporum

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.
MAT loci function as bistable switches in the asexual plant‐pathogenic fungus Fusarium oxysporum, controlling population behaviour through autocrine pheromone signalling. MAT1‐1 promotes hyphal fusion and virulence while repressing germination. MAT1‐2 has opposite effects, upregulating Bar1 protease that cleaves α‐pheromone.

3-Methylthiopropionic Acid of Rhizoctonia solani AG-3 and Its Role in the Pathogenicity of the Fungus

The Plant Pathology Journal, 2016
Studies were conducted to determine the role of 3-methylthioproprionic acid (MTPA) in the pathogenicity of potato stem canker, Rhizoctonia solani, and the concentrations required to inhibit growth of R.
