Gene regulation in Aspergillus: From genetics to genomics

A fundamental aspect of any organism’s success is the ability to monitor and respond effectively to its environment, a process which is largely achieved through the appropriate regulation of gene expression. There are few better examples than fungi, which inhabit diverse and often hostile environments, ranging from leaf litter to the human body. Regulation can occur at many levels, and as we investigate specific genes in detail, the paradigm is one of increasing complexity. We will briefly review the different levels at which regulation is known to occur in Aspergillus and the insights gained from the available genome sequences
