Live-cell imaging was essentially performed as described (Barrales et al., 2016 (link)). In brief, cells were grown overnight in rich medium (YES) to the logarithmic phase (OD600 = 0.4–0.6). Before imaging, cells were attached to lectin (Sigma) coated glass-bottom dishes containing a microwell (MatTek). Cells were imaged using a Zeiss AxioObserver Z1 confocal spinning disk microscope with an EMM-CCD camera (Photometrics, Evolve 512) through a Zeiss Alpha Plan/Apo ×100/1.46 oil DIC M27 objective lens. Z-stacks were obtained at focus intervals of 0.4 μm. FiJi/ImageJ software was used to count the number of foci in the yeast cells.
