boi controls follicle stem cell proliferation. Germaria from wild-type in which germ cells (blue, anti-Vasa) and differentiating follicle cells (red, anti-Fas3) are labeled. Stalks between the germari...

Boi (red) localizes predominantly to apical cells in Drosophila wild-type germaria but not in germaria with UAS-boi[RNAi] expression (CIL#13742). Germ cells are identified using anti-Vasa (blue). Imag...

Expression of UAS-tauGFP (the tau-GFP fusion protein binds microtubules; green) under control of 109-30-Gal4 in wild-type Drosophila germaria. 109-30-Gal4 drives UAS-tauGFP expression in follicle ste...

Expression of UAS-tauGFP (the tau-GFP fusion protein binds microtubules; green) under control of babGal4 in wild-type Drosophila germaria. babGal4 is expressed at high levels in apical cells. Nuclei a...

Boi (green) localizes predominantly to apical cells in Drosophila wild-type germaria but not in boi[e] mutant germaria (CIL#13740). Germ cells are identified using anti-Vasa (blue). Image is Fig 2B in...

Boi (green) no longer localizes predominantly to apical cells in Drosophila boi[e] mutant germaria (compare with CIL# 13739). Germ cells are identified using anti-Vasa (blue). Image is Fig 2C in J Cel...

Boi (red) localizes predominantly to apical cells in Drosophila wild-type germaria (CIL# 13741) but not in germaria with UAS-boi[RNAi] expression in apical cells (cells expressing UAS-boi[RNAi] also e...

Hedgehog (Hh, red) is transcribed in apical cells of the Drosophila wild-type germarium (CIL# 13755, 13744). In the absence of boi (boi[e] mutant), Hh protein is redistributed from apical cells to the...
