(a) Fluorescent reporters used for imaging. (b) Overlay of the mCherry and YFP channels, starting at the first cell division following the re-introduction of clr4+ through a cross. At first, cells express both YFP and mCherry (yellow-green signal). As they divide, a few cells silence YFP (red signal). The silenced state is inherited clonally in their progeny. Scale bar, 5 μm. Additional timepoints and separate channels are shown in Supplementary Movies 1-3.
