Figure 5. Scalloped-Mediated Repression of Or59c .

Figure 5

(A) Predicted Sd binding site downstream of Or59c.

(B and C) Expression of a sd enhancer trap line, sdETX4, visualized by X-gal staining (B) and anti-βGAL antibody staining (C).

(D) RNA in situ hybridizations to maxillary palps of wild type and sd1, a hypomorphic allele.

(E) Numbers of Or RNA positive cells per maxillary palp (n = 10; SEM).

(F and G) Optical sections of sdETX4 maxillary palps labeled with anti-βGAL antibody (green) and RNA probes (red) for Or59c (F) and Or42a (G). Arrowheads in (F) indicate βGAL+ cells paired with Or59c+ cells.

(H) Optical sections of double-label in situ hybridizations to maxillary palps of two sd mutants. Arrowheads indicate Or85d+Or59c+ cells.
