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