During growth in shake flasks, a mutant deleted for SFP1 shows a small size phenotype and a reduced growth rate. We characterized the behaviour of an sfp1Δ mutant compared to an isogenic reference strain growing in chemostat cultures at the same specific growth rate. By studying glucose (anaerobic)- and ethanol (aerobic)-limited cultures we focused specifically on nutrient-dependent effects. Major differences in the genome-wide transcriptional profiles were observed during glucose-limited growth. In particular, Sfp1 appeared to be involved in the control of ribosome biogenesis but not of ribosomal protein gene expression. Flow cytometric analyses revealed size defects for the mutant under both growth conditions. Our results suggest that Sfp1 plays a role in transcriptional and cell size control, operating at two different levels of the regulatory network linking growth, metabolism and cell size., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/mic.0.2007/011767-0
