The fungal genus of Aspergillus is highly interesting, containing everything from industrial cell factories over model organisms to human pathogens. In particular, this group has a prolific production of bioactive secondary metabolites (SMs). In this work, four diverse Aspergillus species (A. campestris, A. novofumigatus, A. ochraceoroseus and A. steynii) has been whole genome PacBio sequenced to provide genetic references in three Aspergillus sections. Additionally, A. taichungensis and A. candidus were sequenced for SM elucidation. Thirteen Aspergillus genomes were analysed with comparative genomics to determine phylogeny and genetic diversity, showing that each new genome contains 15–27% genes not found in other sequenced Aspergilli. In particular, the new species A. novofumigatus was compared to the pathogenic species A. fumigatus. This suggests that A. novofumigatus can produce most of the same allergens, virulence and pathogenicity factors as A. fumigatus suggesting that A. novofumigatus could be as pathogenic as A. fumigatus. Furthermore, SMs were linked to gene clusters based on biological and chemical knowledge and analysis, genome sequences and predictive algorithms.
