  1. ND: Not defined.
  2. The diameter of the FM4-64-stained cell plate was measured as shown in Figure 4A. Values are arithmetic means ± SE, n = 12. Cell plate area was estimated by assuming that the cell plate is a perfect circle (Area = π (Diameter)2/4). Diameters at 1 and 2 min after initiation of cell plate formation (Table 1, BA treatment) could not be defined because the emerging cell plate was deformed in BA-treated cells (see Fig. 3C, 2 min and Fig. 5).
