31 secondary metabolism clusters present in A. fumigatus.

The first 18 secondary metabolism clusters are the ones we predict to be positively regulated by GipA, while the last 13 did not have any genes up-regulated >2-fold from the microarray data.*Cluster ranges for unknown products are defined in [52] or were predicted using SMURF at http://jcvi.org/smurf/index.php.1Although several genes in this cluster have been shown to be involved in production of fumiquinazolines, PesL (Afu6g12050) was recently revealed to be necessary for fumigaclavine C production.
