Fig. 1. Depletion of Nop15p leads to abrupt growth arrest. Growth curves of GAL::nop15 strains following transfer to glucose medium, with and without expression of Rpl25p-eGFP. Strains were pre-grown in RGS medium and transferred to glucose medium for the times indicated. Strains were maintained in exponential growth by dilution with pre-warmed medium. Cell densities measured by OD₆₀₀ are shown corrected for dilution. Wild-type (open squares); GAL::nop15; (filed diamonds); GAL::nop15; rpl25-GFP (filled squares).
