Live imaging of cycle 14 mitotic domains. (A) Tubulin-GFP. Dividing cells are clustered in mitotic domains (box). (B) Magnification of box in A. (C) Dlg-GFP. Cells within a mitotic domain enter mitosis as a cluster and divide in a characteristic order. (D) Dlg-GFP is uniform cortical during cytokinesis. Bars: (A) 10 μm; (B–D) 5 μm.
