A thorough understanding of the ecology and population biology of aflatoxin-producing fungi is a prerequisite for devising new strategies for controlling aflatoxin in peanuts. We have examined populations at three spatial scales.
Single peanut field in Georgia: Population structure is complex and aflatoxin production by fungi is extremely variable.
Aflatoxin production by different genetic groups
Transect through the southern United States: Peanut-growing regions having severe aflatoxin outbreaks are dominated by toxigenic strains of Aspergillus flavus.
Worldwide populations where peanuts are grown: On-going study in collaboration with North Carolina State University shows large differences in population structure and genetic composition.
