Transcription profiling of S. cerevisiae S. cerevisiae strain CEN.PK113.7D and the isogenic sfp1 null mutant were grown in chemostat cultures under ethanol(aerobic)- and glucose(anaerobic)- limitation to determine SFP1 dependent transcription

ABSTRACT: In Saccharomyces cerevisiae growth, size control and cell cycle progression are strictly coordinated and regulated according to the nutritional conditions. In particular, ribosome biogenesis appears a key event in this regulatory network. SFP1 encodes a zinc-finger protein promoting the transcription of a large cluster of genes involved in ribosome biogenesis. It has been suggested that Sfp1 is a cell size modulator acting at Start. To better study the regulatory role of Sfp1 and its putative involvement in cell size and cycle control, we analysed the behaviour of an sfp1 null mutant strain and of an isogenic reference strain growing in chemostat cultures. This approach allowed us to analyze both strains at the same specific growth rate, thus eliminating the secondary effects due to the sl
