A rapid technique for trichothecene detection was needed in screening tests of the potential bioherbicide Myrothecium verrucaria (MV), in order to select strains, mutants, or formulations that were void of or that possessed low amounts of these undesirable mycotoxin compounds. Commercially available enzymelinked immunosorbent assay (ELISA) plates for trichothecene detection, possessing cross-re...
Non-volatile sesquiterpenoids, a trichothecene family of phytotoxins such as deoxynivalenol (DON) and T-2 toxin, contain numerous molecular species and are synthesized by phytopathogenic Fusarium species. Although trichothecene chemotypes might play a role in the virulence of individual Fusarium strains, the phytotoxic action of individual trichothecenes has not been systematically studied. To ...
The Hypocrealean epibiont of Baccharis coridifolia has been shown to synthesize de novo a series of macrocyclic trichothecene antibiotics, such as roridin A, roridin E, verrucarin A and verrucarin J. The structures of the compounds were determined by spectroscopic methods (1Hand 13C-NMR and FABMS).
Pentahydroxyscirpene, a novel trichothecene-type compound, was isolated from Fusarium-inoculated rice. The structure of pentahydroxyscirpene was elucidated by 1D and 2D NMR spectroscopy and X-ray single-crystal diffraction. The conformation in solution was determined by NOESY experiments supported by quantum chemical calculations. In vitro toxicity tests showed that pentahydroxyscirpene inhibit...
The trichothecene mycotoxin deoxynivalenol (DON) is a common contaminant of small grains, such as wheat and barley, in the United States. New strategies to mitigate the threat of DON need to be developed and implemented. TRI101 and TRI201 are trichothecene 3-O-acetyltransferases that are able to modify DON and reduce its toxicity. Recent work has highlighted differences in the activities of TRI...
