Movie 6.

Addition of new spectrosome material in CBs. 480-minute-long time-lapse movie showing the incorporation of new GFP::Par-1-positive material into the CB spectrosome (white open arrows). Most of the new material is generated in the posterior half of the cell (t = 170′ to 440′). Note the large lump of new material that starts appearing at t = 290′ and that will eventually fuse at the posterior with the drifting CB spectrosome that results from the abscission of the GSC/CB intercellular bridge (t = 460′). Asterisk: GSC; CB: cystoblast. The movie is a maximum projection of 5–9 z-planes (1 μm each) per time point (taken every 10 minutes). While this germarium is the same as the one shown in Movie S9, the z-planes selected to compose this movie are different. Related to Fig. 2C.
