Fig. 5. Abd-B distribution in wild-type, bicoid, hid bicoid and torso;bicoid embryos. Lateral views of stage 8 (A,B) and stage 15 (C-F) wild-type (A,C), bicoid (B,D), hid bicoid (E) and torso;bicoid (F) mutants labeled with anti-Abd-B antibodies. Wild-type embryos (A,C) contain Abd-B protein in the posterior region only. In bicoid mutant embryos (B,D), Abd-B protein is present at the posterior and at the anterior pole (see arrow in B). The brackets in C-E indicate the dorsally located component of Abd-B expression that develop into telson structures. Cell death clears part of the mis-specified area at the anterior (open arrow in D). Tissue clearance does not occur in hid bicoid double mutants (E). The red arrows in C-E indicate the relative position that specifies A8 segments in wild-type (C), bicoid (D) and hid bicoid (E) mutants. In torso; bicoid double mutants (F), the dorsally located component of anterior Abd B expression as well as the ventral and the posterior component are cleared (open arrows in F).
