Figure 4. ftz is required for expression of the primary drm stripes independent of en.

Figure 4

Confocal images of embryos double stained for drm mRNA and Ftz protein (A,C) or ftz RNA (B). (A)Ftz and drm overlap in the primary drm stripes. OreR, stage 6 embryo: drm RNA (red), Ftz protein (green). (B)Primary drm stripes are lost in ftz mutants. ftz9H34 stage 5 embryo: drm RNA (red), ftz RNA, (green). The remaining drm stripes in the ftz mutant embryo are out of register with the ftz stripes. (C)Primary drm stripes do not require en. Stage 6 en embryo: drm RNA (red), Ftz protein (green). No change in the Ftz-dependent drm stripes was observed in en mutants.
