Fig. 4From: Molecular breeding of Saccharomyces cerevisiae with high RNA content by harnessing essential ribosomal RNA transcription regulatorDetermination of rDNA copy number of ∆fob1Sup mutants. rDNA copy number in ∆fob1Sup mutants with or without pRRN5 determined by quantitative real-time PCR. Experiments were performed in triplicates. Grey bars ∆fob1Sup mutants, white bars ∆fob1Sup mutants harboring pRRN5Back to article page
