Interpretive Summary: Genome sequences have been valuable for genomics-assisted studies for gene functional characterization and primary and secondary metabolic pathways. Aspergillus flavus and A. parasiticus are opportunistic pathogens of corn and peanut. These fungi produce carcinogenic aflatoxins with extensive variation in production among isolates ranging from atoxigenic to highly toxigenic. Here, we conducted whole genome sequences of one A. parasiticus, and nine A. flavus isolates from the fields. These genome sequences will be released to public database such GenBank and will be used in comparative, functional, and phylogenetic studies in order to search mitigation strategies of aflatoxin contamination in these commodities.

Technical Abstract: Aspergillus flavus and A. parasiticus are saprophytes, and opportunistic pathogens of maize and peanut. These fungi produce carcinogenic aflatoxins with extensive variation in production among isolates ranging from atoxigenic to highly toxigenic. Here, we report draft genome sequences of one A. parasiticus, and nine A. flavus isolates from field environments. These genome sequences will be used in comparative, functional, and phylogenetic studies for searching mitigation strategies of aflatoxin contamination.
