Analysis of substrate specificity of cytochrome P450 monooxygenases involved in trichothecene toxin biosynthesis
Trichothecenes are a structurally diverse family of toxic secondary metabolites produced by certain species of multiple fungal genera. All...

Impact of nitrogen metabolism-associated culture pH changes on regulation of Fusarium trichothecene biosynthesis: revision of roles of polyamine agmatine and transcription factor AreA
Fusarium graminearum produces trichothecene mycotoxins in infected grains and axenic liquid culture. A proposed regulatory model of trichothecene...

Genetic bases for variation in structure and biological activity of trichothecene toxins produced by diverse fungi
AbstractTrichothecenes are sesquiterpene toxins produced by diverse but relatively few fungal species in at least three classes of Ascomycetes : Dothideomycetes...

Mechanisms of Control by Pseudomonas Fluorescens of Barley Root Rot Caused by Fusarium culmorum
In this paper, we determined the reason that the intensity of barley fusarium root rot caused by Fusarium culmorum 30 decreases in the presence of...

Epipolythiodiketopiperazine and trichothecene derivatives from the NaI-containing fermentation of marine-derived Trichoderma cf. brevicompactum
The marine-derived fungus Trichoderma sp. TPU199 (cf. Trichoderma brevicompactum ) produces pretrichodermamide A ( 1 ) and gliovirin ( 2 ), which possess...

Relationship Between Mycotoxin Production and Gene Expression in Fusarium graminearum Species Complex Strains Under Various Environmental Conditions
The Fusarium graminearum species complex (FGSC) can produce various mycotoxins and is a major concern for food quantity and quality worldwide. In...

Survey of zearalenone and type-B trichothecene mycotoxins in swine feed in the USA
New information is needed regarding the types and concentrations of mycotoxins in swine feed. We hypothesized that (1) the mycotoxins deoxynivalenol...

Overexpression of wheat spermidine synthase gene enhances wheat resistance to Fusarium head blight
Polyamines, such as putrescine, spermidine, and spermine, are crucial for plant defense against both abiotic and biotic stresses. Putrescine is also...

Review of neurotoxicity of T-2 toxin
T-2 toxin is a representative trichothecene that is widely detected in corn, wheat and other grain feeds. T-2 toxin has stable physical and chemical...

Combatting Fusarium head blight: advances in molecular interactions between Fusarium graminearum and wheat
Fusarium head blight (FHB), mainly caused by Fusarium graminearum , is one of the most devastating diseases in wheat and barley worldwide. In addition...
