Background: Microbial gene expression is to a large extend determined by environmental growth conditions. Differential gene expression analysis between two conditions has been frequently used to reveal regulatory networks and to assign physiological function to unknown genes. In nature, microorganis...
ORGANISM(S): Penicillium chrysogenum 
The multi-component global regulator Velvet complex has been identified as a key regulator of secondary metabolite production in Aspergillus and Penicillium species. Previous work indicated a massive impact of PcvelA and PclaeA deletions, two key components of the Velvet complex, on penicillin produ...
ORGANISM(S): Penicillium chrysogenum 
Industrial production of penicillin G by Penicillium chrysogenum requires medium supplementation with the side chain precursor phenylacetate. However, P.chrysogenum grown in presence of phenylalanine as sole nitrogen source formed detectable extracellular amounts of phenylacetate and penicillin G. T...
