Kni is an additional repressor of anterior tll. (a)–(d) Expression pattern of kni in wild-type embryos (a), embryos that lack Bcd (b), Dl signaling (c), or Cic (d). (e) Expression pattern of kni in embryos with one copy of bcd. (f) A model for the regulation of anterior-ventral stripe pattern of kni by Bcd, Dl, and Torso signaling. (g) Lateral view of an embryo co-stained for kni (green) and tll (red) mRNAs. (h) tll expression pattern in an embryo that lacks Kni and Hkb.
