Influence of HO-Induced Oxidative Stress on In Vitro Growth and Moniliformin and Fumonisins Accumulation by and .

and are common pathogens of maize which are known to produce mycotoxins, including moniliformin (MON) and fumonisins (FBs). Fungal secondary metabolism and response to oxidative stress are interlaced, where hydrogen peroxide (HO) plays a pivotal role in the modulation of mycotoxin production. The objective of this study is to examine the effect of HO-induced oxidative stress on fungal growth, as well as MON and FBs production, in different isolates of these fungi.

Fusarium Toxins in Cereals: Occurrence, Legislation, Factors Promoting the Appearance and Their Management.

Fusarium diseases of small grain cereals and maize cause significant yield losses worldwide. Fusarium infections result in reduced grain yield and contamination with mycotoxins, some of which have a notable impact on human and animal health. Regulations on maximum limits have been established in various countries to protect consumers from the harmful effects of these mycotoxins.

In Vitro Production of Fumonisins by Fusarium verticillioides under Oxidative Stress Induced by H2O2.

The effects of oxidative stress induced by H2O2 were tested in liquid cultures in the fumonisin-producing fungus Fusarium verticillioides. The quantitative analysis of fumonisins B1, B2, B3, and B4 was achieved by means of liquid chromatography coupled to high-resolution mass spectrometry. Two effects in F.

A cDNA-AFLP approach to study ochratoxin A production in Aspergillus carbonarius.

Aspergillus carbonarius is responsible for the majority of mycotoxin contaminations in grapes and its derivatives. Most of A. carbonarius strains are ochratoxin A (OTA) producers, even though at very different levels.
