Interpretive Summary: Designing molecular tools for the control of mycotoxin accumulation in seeds, requires knowing the DNA sequence of the fungal pathogens invading those seeds. We have identified the most common Aspergillus fungi colonizing peanut seeds in Ethiopia, and now have sequenced the genomes of the 17 isolates most commonly found. The data will allow mining for target sequences to use in the control of mycotoxin accumulation.

Technical Abstract: Here we report the genome sequences of 17 isolates of Aspergillus flavus Link and Aspergillus parasiticus Speare identified as the predominant genotypes colonizing peanuts in four farming regions of Ethiopia. The availability of these data will allow mining for consensus sequences that could be targeted by molecular tools such as the use of RNA interference (RNAi) to prevent aflatoxin accumulation in peanut seeds in those regions.
