Fig. 4. N activation downregulates slp expression.(A-A'') Clones of N^intra (green, arrows) show downregulation of slp-lacZ expression (red). (B,C) The effects of a 24-hour temperature shift on N^ts/+ control discs (B) and N^ts/Y experimental discs (C) stained for slp-lacZ (green) and Mirr (red). In the control, the gap (arrowhead) forms normally, but in the N^ts/Y, slp transcription is unaffected and the gap fails to form.
