Expression of eve in the regio germinalis. All embryos are oriented with anterior to the left and represent ventral views, except panel (B), which represents a posterior view. Ventral (A) and posterior (B) view on an early blastoderm (stage 01) embryo. Asterisk in (B) marks posterior pole of the embryo. (C) Later blastoderm stage embryo (stage 02) double-stained for eve (blue signal) and col (orange signal). (D) Late blastoderm stage embryo (stage 03) double-stained for eve and col. (E) Stage 0.1 embryo. (F) Stage 0.31 embryo double-stained for eve and col. Note that eve is not expressed in the mandibular segment. (G) Stage 0.32 embryo. (H) Stage 0.4 embryo. The full set of anterior eve-stripes has appeared. Abbreviations as in Figure 1.
