somatic follicle cells to acquire dorsal fates (Figure 1). In the absence of the signal (Gurken, a TGF-␣ family member) or the receptor (DER, the Drosophila EGF receptor), the follicle cells differentiate like ventral follicle cells. The second signaling pathway acts after fertilization when a ventral extracellular cue triggers the activation of Spä tzle, which activates Toll and thereby pro-By now it has become generally accepted that morpho-motes nuclear localization of Dorsal.
