Figure 2. Nuclear membrane fusion is disrupted in bmb mutants.

Figure 2

(A) Frames from time-lapse experiments at the telophase-interphase transition demonstrate that chromatin bodies normally coalesce in WT (top) but fail to do so in bmb− (bottom). Note: 6 frames were selected (from Movie S1 and S2 to best align the sequence of events between WT and bmb− at the telophase to interphase transition. (B) Electron microscopy of WT versus bmb− at the telophase-interphase transition. Embryos at the 128-cell stage were fixed at 90-second intervals for TEM. Black bar = 2 microns. The inset in WT (0 min) is enlarged 2X to show the double membrane nuclear envelope. For each time point n=2 embryos. Multiple cells from each embryo were examined in both WT and bmb−.
