Description
Diacetoxyscirpenol (DAS) is a potent, trichothecene mycotoxin produced by certain Fusarium strains, which play an important role as plant pathogens, causing a wide range of diseases.1 It is toxic to fungi, plants, animals, and various mammalian cell cultures, inhibiting de novo protein synthesis.2 In a biological activity assay, DAS was shown to inhibit expression of the Arabidopsis MAMP-responsive reporter gene WRKY29p::GUS with an IC50 value of 50 nM, thereby suppressing a rapid cell death immune response important for plant defense.3
