Figure 7

Expression of opa and odd in the regio germinalis . All embryos are oriented with anterior to the left and represent ventral views. (A) Expression of opa in a blastoderm stage embryo. Asterisks mark stripes of enhanced expression within a field of ubiquitous expression. (B) Expression of opa in a stage 0.3 embryo. Asterisks as in (A). Additional stripes of segmental expression form. (C) Stage 0.4 embryo expressing opa. Asterisks as in (A). The arrow points to expression in T2. (D) Expression of odd in a blastoderm stage embryo. Arrow points to expression at the very anterior of the embryo. Arrowhead points to weak expression anterior to the SAZ. Asterisk marks expression at the posterior pole of the embryo. (E) Stage 0.5 embryo stained for odd expression. Arrow as in (D). Asterisk marks dorsal expression within the gnathal segments. Abbreviations as in Figure 1.
