Phytotoxin Produced byNimbya scirpicola [PDF]

Bioscience, Biotechnology, and Biochemistry, 1994
A phytotoxic substance isolated from the weed pathogen Nimbya scirpicola was identified as depudecin by spectral data nalyses. It was found that depudecin had phytotoxic activity toward the host plant of this fungus, kuroguwai, and toward other tested plants, and inhibited the root elongation of lettuce seedlings.

Curvulin and Phaeosphaeride A from Paraphoma sp. VIZR 1.46 Isolated from Cirsium arvense as Potential Herbicides

Molecules, 2018
Phoma-like fungi are known as producers of diverse spectrum of secondary metabolites, including phytotoxins. Our bioassays had shown that extracts of Paraphoma sp. VIZR 1.46, a pathogen of Cirsium arvense, are phytotoxic.

Detoxification of Mycotoxins through Biotransformation

Toxins, 2020
Mycotoxins are toxic fungal secondary metabolites that pose a major threat to the safety of food and feed. Mycotoxins are usually converted into less toxic or non-toxic metabolites through biotransformation that are often made by living organisms as well

Natural Variations in the Activity of Hydroxycinnamoyl Transferases Promote Accumulation of Metabolites Conferring Rice Resistance

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3803-3820, June 2026.
ABSTRACT Plant‐derived secondary metabolites act as regulators of in planta defence. Plant phenylpropanoid metabolic compounds, including final metabolites such as lignin and flavonoids, and a few intermediate metabolites play critical roles in defence.

The Basic Helix–Loop–Helix Transcription Factors UvBhlh1 and UvBhlh6 Coordinate Virulence in the Rice False Smut Fungus Ustilaginoidea virens

Molecular Plant Pathology, Volume 27, Issue 5, May 2026.
Transcription factors UvBhlh1 and UvBhlh6 are essential for early infection and virulence in Ustilaginoidea virens. These two proteins form a heterodimer that cooperatively regulates downstream target genes during pathogenesis. ABSTRACT Ustilaginoidea virens is the causal agent of rice false smut, a devastating and globally widespread fungal disease ...

Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways

Advanced Science, Volume 13, Issue 19, 2 April 2026.
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.

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.
