Successive cytokinesis in one anther of a VF cdka;1/− cdkd;3/+ mutant flower. Tubulin (RFP) in magenta highlights microtubules from late prophase to tetrad formation, and the bright-field image (cell shape) appears in gray. Cell wall deposition is observed after the first meiotic division (first cytokinesis), followed by the assembly of two spindles and a second cell wall deposition after the second meiotic division (second cytokinesis). See also Fig. 5 B. The interval between image acquisitions is 10 min. Time format (h:min). Scale bar, 10 µm. Frame rate is 5 frames per second.
