Transcript profiles of the amplified region in penicillinG-producing strains of Penicillium chrysogenum. Transcript level of the penicillin biosynthesis genes embedded in a region that is present in tandem repeats in penicillinG-high-producing strains, the amplified region (Pc21g21280–Pc21g21420, [17,34,40]). Total RNA was obtained from P. chrysogenum strains DS17690 and DS50661, grown in the presence and absence of phenylacetic acid (PAA) in independent glucose-chemostat cultures at D = 0.03 h-1 and hybridized to Affymetrix GeneChip® microarrays.
