Fig. 4. hyd regulates dpp but not hh through Ci.
(A,B,D-F) Third instar eye discs with anti-Elav staining in red.
hydK7.19 clones expressing UAS-ci76 with
tub-GAL4 are positively marked by GFP expression in B,E,F. (A,B)
Anti-ß-galactosidase staining reflecting dpp-lacZ expression in
blue. (D,F) Anti-ß-galactosidase staining reflecting hh-lacZ
expression in blue. Expression of Ci76 in hyd clones
blocks dpp expression but not hh expression. (C) An adult
eye with hydK7.19, hhrJ413 clones expressing
UAS-ci76. No overgrowth is visible.
