Figure 3From: Repressible promoters – A novel tool to generate conditional mutants in Pichia pastorisDown-regulation of expression in liquid culture. Relative transcript levels of ERO1 and PDI1 under control of the repressible promoters P THR1 and P THI11 in non- repressing and repressing conditions, as determined by qRT-PCR. They are compared to the relative transcript level of the respective native promoter.Back to article page
