  • Title: Group specific PCR-detection of potential trichothecene-producing Fusarium-species in pure cultures and cereal samples.
    Author: Niessen ML, Vogel RF.
    Journal: Syst Appl Microbiol; 1998 Dec; 21(4):618-31. PubMed ID: 9924828.
    Abstract:
    A PCR based assay (Tox5 PCR) which analyses Fusarium species potentially producing trichothecenes was developed using a pair of primers derived from the DNA-sequence of the trichodiene synthase gene (tri5). The primer pair was tested using DNA isolated from a variety of strains representing 64 species and varieties of Fusarium as well as from other fungi, bacteria and cereals. A 658 bp PCR fragment was specifically amplified with DNA isolated from strains of species belonging to the Fusarium sections Discolor, Sporotrichiella, Arthrosporiella, Gibbosum, and "Dlaminia". PCR products obtained were sequenced. Alignment to tri5 sequences given in the literature revealed a high degree of homology. Results of the PCR developed correlated well with literature data on the trichothecene producing capabilities of the respective species. Potential trichothecene producing fusaria were detected in contaminated cereals and malts using the Tox5 PCR assay. Intensity of the signals produced were well correlated with the concentration of deoxynivalenol (DON) in samples of wheat.
