Interpretive Summary: The fungus Aspergillus (A.) flavus is important to agriculture, human health and industry. We present here the genome sequence of twenty isolates from known points in the Mississippi Delta for use in evaluating the site-specific genetic diversity of A. flavus. This whole genome sequence is valuable for basic biological, agricultural and epidemiological research by facilitating the identification of specific strains.

Technical Abstract: Several agricultural commodities and food products can be infected by Aspergillus flavus, a saprophytic fungus that can produce the carcinogenic mycotoxin,aflatoxin. Understanding the ecology of this crop pathogen is in part dependent on identifying the diversity of the population at a species level. Here we report on the whole genome sequencing for twenty geo-referenced isolates of A. flavus collected from soil and infected corn under field conditions. This genetic information contributes to the information available on population structure and dynamics within A. flavus communities in a field environment.
