SIM imaging of FtsZ2–mYFP mini-rings and filamentous assemblies in leaf mesophyll chloroplasts. a Maximum intensity projection showing both filaments and mini-rings in an enlarged leaf chloroplast. The dashed line delineates the shape of the chloroplast. Some mini-rings appear attached to the end of linear FtsZ filaments (arrows), while others are unattached (arrowheads). b Distribution of mini-ring diameters. c Optical sections showing FtsZ mini-rings contiguous with linear FtsZ filaments. Scale bars correspond to 5 µm in a and 1 µm in c
