• Supplemental Figure S1 -

  Fig. S1. The detection of HRP-Gurken. Anterior of the egg chamber is towards the left and dorsal side faces upwards. (A-C) The Gurken signal (red) detected by the anti-Grk antibody mostly overlapped with the HRP signal (green) in the oocyte and posterior follicle cells in stage 7 egg chambers. However, some extra HRP punctate signals were detected in follicle cells (arrows in B,C). (D-I) Similarly, Gurken signals were all HRP positive in the oocyte and dorsal follicle cells in stage 9 egg chambers (D-F), but some HRP signals were Gurken negative in the dorsal and ventral follicle cells (arrows in D-F,I). Scale bars: 10µm.

• Supplemental Figure S2 -

  Fig. S2. Expression pattern of GR1-Gal4 in follicular epithelium of Drosophila. The nls-GFP expression driven by GR1-Gal4 reflected different levels of expression in individual follicle cells in the cross-section (A) and the surface section (B). Scale bars: 20 µm.
