Expression profile of the A. niger pyrG and hisB genes. Our in-house transcriptomic database for A. niger covering 155 growth conditions was analyzed for hisB and pyrG expression levels. Gene expression levels were normalized against actin (actA) expression during the exponential growth phase of A. niger in maltose-based bioreactor cultivation. For improved visualization, data were assorted ascending for the pyrG expression level
