(A) An asynchronous culture of GAL-SIC1ΔNT GLN3-9MYC (YMF4471) was grown at 30 °C in medium lacking galactose. After the addition of nocodazole, culture was synchronised in G2-M phase for 1 generation time. Cells were then transferred to fresh medium containing galactose to allow overexpression of SIC1ΔNT. Cells were maintained as well as in nocodazole. Cell extract were made over the course of 2 h to examine Gln3 mobility. Raw data for blots can be found in Supporting information (S1 Raw Images). (B) TUB1-GFP cdc15-2 (YMF3976) cells were grown in YPD and arrested in late anaphase by raising the temperature to 37 °C before the addition of rapamycin to half of the culture. Subsequently, to allow progression through the cell cycle, cells were released in the absence (−) or presence (+) of rapamycin. Samples were taken at the indicated times. Using fluorescence microscopy, the proportion of cells with anaphase spindles in the absence (i) or presence (ii) of rapamycin was investigated. Examples of TUB1-GFP cdc15-2 cells at 120 min after the release at 24 °C are shown in the absence (iii) or presence (iv) of rapamycin. Scale bars indicate 5 μm. (C) cdc15-2 cells (CC2274) were grown in parallel with strains for Fig 2A, but instead or releasing cells at the permissive temperature of 24 °C after the addition of rapamycin like in Fig 2A, cells were maintained at the restrictive temperature of 37 °C in the presence of rapamycin (i). Samples were taken at the indicated times to determine DNA content by flow cytometry analysis (ii) and cell morphology at the end of the experiment (iii). Scale bars indicate 5 μm. (D) cdc14-1 cdc15-2 cells (CC6441) were grown in YPD and arrested in late anaphase by shifting the temperature to 37 °C before the addition of rapamycin to half of the culture (ii). Then, cells were released at 24 °C in the absence (i) or presence (ii) of rapamycin. Samples were taken at the specified times to determine DNA content by FACS analysis. Using light microscopy, we studied cell morphology in the absence (iii) or presence (iv) of rapamycin at the 120 min time point after the release from late anaphase arrest. Scale bars indicate 5 μm. (E) INN1-GFP cdc15-2 (YMF3162) cells were grown as in A. Samples were taken at the indicated times. The proportion of cells with total Inn1-GFP signal in the absence (i) or presence (ii) of rapamycin was determined using fluorescence microscopy. The percentage of cells with either medial rings or spots of Inn1-GFP was calculated too. Examples of cells expressing Inn1-GFP 30 min after the release are shown in the absence (iii) or presence (iv) of rapamycin. Scale bars indicate 5 μm. (F) 3GFP-RAS2 cdc14-1 cells (CC6296) were grown as described in A. Cells are shown at 120 min after the release in the absence (i) or the presence (ii) of rapamycin. Red arrows denote cells where examination of each z-level at the bud neck showed divided cytoplasm and new buds are marked with white asterisks. Scale bars indicate 5 μm. Underlying data for all the graphs can be found in S1 Data file. FACS graphs can be found in the supplementary FACS file (S1 File)., journal.pbio.3002263.s001.pdf, Peer reviewed
