Fig. 4 GATA-2 expression at 75% epiboly in janus-mutant embryos. (A) Wild-type embryo. GATA-2 expression marks the nonneural ectoderm in a 180° arc. Boundaries of normal expression are indicated by arrowheads. (B) janus-mutant embryo in which the shield contributes to the two blastoderms. Each half-blastoderm has a ventral GATA-2 expression domain (ve). (C) janus-mutant embryo in which the entire shield is localized to one blastoderm. Only the ventral half-blastoderm has GATA-2 expression. Animal view. (B, C) Separated blastoderms are flattened for documentation. Asterisk indicates position of shield. ve, ventral side. Scale bar is 100 μm.
