Aflatoxins, <strong>the</strong> Toxins that Redefined Plant Disease<br />
9:00 – 11:30 a.m. * 205 CD<br />
Section: Biology of Pathogens<br />
Organizers: Gary Payne, North Carolina State University,<br />
Raleigh, NC; Peter Cotty, USDA/ARS, University of Arizona,<br />
Tucson, AZ<br />
Moderator: Charles Woloshuk, Purdue University, West<br />
Lafayette, IN<br />
Sponsoring Committees: Mycotoxicology<br />
Although <strong>the</strong> toxicity of diseased plants to humans has been<br />
recognized for hundreds of years, aflatoxin contamination<br />
remains <strong>the</strong> best-described example of this link. Research<br />
on this toxin ushered in <strong>the</strong> modern era of mycotoxicology,<br />
and aflatoxin remains <strong>the</strong> best-described mycotoxin. It has<br />
been 50 years since aflatoxin was shown to be <strong>the</strong> cause<br />
of <strong>the</strong> mysterious Turkey X disease. It is now recognized<br />
as one of <strong>the</strong> most potent naturally occurring carcinogens<br />
known, and it continues to affect human and animal health<br />
and international trade. The impact of aflatoxins on human<br />
populations in both Asia and Africa is well documented. This<br />
symposium will commemorate <strong>the</strong> near 50 years of research<br />
on aflatoxin and will highlight its toxicity and importance<br />
to developing countries, its well-characterized biosyn<strong>the</strong>tic<br />
pathway, and recent information gleaned from <strong>the</strong> genome<br />
sequence and available DNA microarrays. Also covered will be<br />
a phylogenetic analysis of <strong>the</strong> aflatoxin-producing species of<br />
Aspergillus and <strong>the</strong> successful use of biocontrol techniques to<br />
control this disease.<br />
