Reduced virulence of Gibberella zeae caused by disruption of a trichothecene toxin biosynthetic gene.
The production of trichothecene mycotoxins by some plant pathogenic species of Fusarium is thought to contribute to their virulence. Gibberella zeae (F. graminearum) is an important cereal pathogenExpand
Trichothecenes: From Simple to Complex Mycotoxins
As the world’s population grows, access to a safe food supply will continue to be a global priority. In recent years, the world has experienced an increase in mycotoxin contamination of grains due toExpand
Global gene regulation by Fusarium transcription factors Tri6 and Tri10 reveals adaptations for toxin biosynthesis
Trichothecenes are isoprenoid mycotoxins produced in wheat infected with the filamentous fungus Fusarium graminearum. Some fungal genes for trichothecene biosynthesis (Tri genes) are known to beExpand
Trichothecene biosynthesis in Fusarium species: chemistry, genetics, and significance.
Several species of the genus Fusarium and related fungi produce trichothecenes which are sesquiterpenoid epoxides that act as potent inhibitors of eukaryotic protein synthesis. Interest in theExpand
Tri6 encodes an unusual zinc finger protein involved in regulation of trichothecene biosynthesis in Fusarium sporotrichioides.
In Fusarium sporotrichioides, several genes required for biosynthesis of the trichothecene mycotoxin T-2 toxin are closely linked. Further characterization of this gene cluster has revealed a gene,Expand
Phylogenetic analyses of RPB1 and RPB2 support a middle Cretaceous origin for a clade comprising all agriculturally and medically important fusaria.
Fusarium (Hypocreales, Nectriaceae) is one of the most economically important and systematically challenging groups of mycotoxigenic phytopathogens and emergent human pathogens. We conducted maximumExpand
Genes, gene clusters, and biosynthesis of trichothecenes and fumonisins in Fusarium
Trichothecenes and fumonisins are mycotoxins produced by Fusarium, a filamentous fungus that can cause disease in barley, maize, rice, wheat, and some other crop plants. Research on the genetics andExpand
TRI12, a trichothecene efflux pump from Fusarium sporotrichioides: gene isolation and expression in yeast
Abstract Many of the genes involved in trichothecene toxin biosynthesis in Fusarium sporotrichioides are present within a gene cluster. Here we report the complete sequence for TRI12, a gene encodingExpand
Evidence that a secondary metabolic biosynthetic gene cluster has grown by gene relocation during evolution of the filamentous fungus Fusarium
Trichothecenes are terpene‐derived secondary metabolites produced by multiple genera of filamentous fungi, including many plant pathogenic species of Fusarium. These metabolites are of interestExpand
Occurrence of Fusarium species and mycotoxins in nepalese maize and wheat and the effect of traditional processing methods on mycotoxin levels.
Maize (Zea mays) and wheat (Triticum aestivum) collected in the foothills of the Nepal Himalaya Mountains were analyzed for Fusarium species and mycotoxins: fumonisins, nivalenol (NIV), andExpand
