Usefulness of Findings

Results reported for 2001 will extend existing knowledge about the toxicity and occupancy of a wide variety of Fusarium mycotoxins in grains. Progress has been made in insect/ fungi relationships beyond the issue of fumonisins in grain, for a more comprehensive model including mycotoxins in silage and stored grain. Research reported in 2001 demonstrates the potential usefulness of using ozone in managing stored maize and possibly other grains. The data indicate that, if repeated ozone treatments are needed, such treatment should not decrease the quality of grain for end-users. A number of unique molecular targets and pathways affected by fumonisin have been identified. For example, it has been shown that fumonisin induces cell cycle arrest and apoptosis in normal cells. Such studies will improve our understanding of the mechanism behind FB1 toxicity and the role of sphingolipids in signal transduction processes. Current data obtained in long term low dose feeding study using purified fumonisin B1 suggest that concerns regarding potential fumonisin B1 induced atherosclerotic effects do not appear warranted. Isolation and characterization of Fusarium genes involved in mycotoxin synthesis continues to aid efforts to control mycotoxin formation in food crops. New technologies and methods for mycotoxin analysis have provided either better, easier or quicker means to detect mycotoxins in foods. Some of our efforts have been toward developing a means to clone fusaric acid biosynthesis genes. Cloned genes would permit the construction of gene knock-out strains that would be useful for a wide range of studies involving fungal interaction with plant species and potentially in animal studies as well. The cooperative approach used by NC-129 contributors is essential to efforts to control mycotoxin formation in food crops.

Work Planned for Next Year
1. Work will continue on the evaluation of the toxic effects of fumonisins and how they might be mitigated. Studies will continue on the acute toxicity of amine-blocked forms of FB1 in swine and rats. Evaluation of potential methods for nixtamalization of corn which will not result in hydrolysis of fumonisin B1 contaminants. Evaluation of potential binders of N-fatty acyl-hydrolyzed fumonisin B1 in extracts from hot oil generated during frying of corn-derived food products. The presence of hydrolyzed FB1 and its derivatives in corn products will continue.
2. The molecular biology of fumonisin biosynthesis remains a priority. Efforts to evaluate newly identified Fusarium strains with regard to mycotoxin production, will continue.
3. Studies will continue on the potential of the adsorbent clays and bacterial enzymes to bind or destroy mycotoxins. Studies will continue on the production of Fusarium verticilloides mycotoxins and feeding studies in poultry and turkeys.
4. Work will continue on the peptide mimic of DON, including the development of transgenic plants, and a determination of the possible role the mimic may have in reducing the toxic effects of DON. Development of recombinant antibody to DON will continue, as will a study to determine the effect of sampling patterns on the estimation of DON levels in individual fields. Trichothecenes will be tested in cytotoxicity and phytotoxicity assays for structure-activity relationships. Rapid fluorescence polarization immunoassays will be developed for FB1 and DON.
5. Attempts are still in progress on methods to increase the resistance of maize to fungal disease by inserting and expressing a gene that provides antifungal proteins in the corn pedicel. The seed transmission and systemic infection of maize by Fusarium species will continue to be studied. F. verticillioides transformants will screened for defects in fusaric acid biosynthesis..
