In March 2003, the Broad Institute publically released a 13X coverage of A. nidulans (FGSC A4) obtained by whole genome shotgun sequencing. As part of an international collaboration to improve the annotation for A. nidulans, A. fumigatus and A. oryzae, a second round of automated gene prediction and annotation was performed on this genome by TIGR (renamed the The J. Craig Venter Institute). This data was publically released in 2005.

More recently (September 2008), this genome has received attention from a group of experts via a European consortium, namely Eurofungbase. This consortium has corrected many gene structures and/or annotations manually. For the remainder, information has been transferred from orthologues (chiefly A. fumigatus and A. niger) where possible.

Using information available from the Broad A. nidulans Website and John Clutterbuck's A. nidulans linkage map Website, we have also attempted to build the most accurate assembly. For further information about this assembly please follow this link. At present, there are eight linkage groups (I to VIII) and a number of unassigned fragments annotated within CADRE.
