Aspergillus versicolor is found in the arctic regions and is a member of the same group as A. nidulans. Comparison of A. niger, A. nidulans and A. oryzae demonstrated significant differences in presence of biomass degrading enzymes and utilisation of carbon sources. As A. nidulans is distant from the other sequenced Aspergilli. Adding A. versicolor will enable a better analysis of the uniqueness of A. nidulans and will strengthen overall comparative genomics. A. versicolor is also the species of choice for comparison by most of the A. nidulans research groups.
