Genomic Investigation of the Aspergillus nomius Type Strain.

Aspergillus nomius is an aflatoxigenic species in Section Flavi. Its morphological characteristics are similar to A. flavus, while its chemotype profile is similar to A. parasiticus in that it produces B- and G-aflatoxins. This organism is capable of pathogenic behavior in plant and animal systems, and due to the recent discovery of its ability to undergo sexual out-crossing, A. nomius may be of greater importance than previously thought. We sequenced the genome of the type strain (NRRL 13137) and found it to have a genome size of 36 Mb which is comparable to other sequenced Aspergilli. Orthology analysis revealed the presence of more than 1,200 genes unique to A. nomius, and the most significantly enriched GO category was oxidoreductase activity. Phylogenomic analysis inferred A. nomius as the ancestor to the other aflatoxigenic species in Section Flavi. An investigation of the mating-type locus revealed NRRL13137 to be heterothallic and possessing a single MAT1-1 idiomorph.
