English: Membrane folds along contours. FM 4–64 channel (top left) and SpoIIIJ-GFP channel (top right) from time lapse fluorescence microscopy from [8]. For a given cell and channel the average pixel intensity along the single mother membrane far from the boundary () is calculated for each time point (as in Fig. 3A). Intensities along all membranes are then scaled by this average intensity. Membrane folds along the contours are shown for FM 4–64 channel (bottom left) and SpoIIIJ-GFP (bottom right) with color scale on the far right. Accumulation of membrane folds at the mother-forespore boundary accompanies engulfment process. Movie length 21.75 minutes.
