Fig. 6. Hth regulation of dac in the antenna. (A,A',B,B') Dac expression (red in all panels) is activated in hth (green) null clones in the antenna. Dac expression is activated distally (arrow in A,A'), medially (arrowhead A,A') and proximally (arrows in B,B') in hth-null clones. (C,C') Ectopic Hth produced in flipout clones in a3 (the normal dac expression domain) either has no effect on dac expression (arrow in C,C') or weakly represses dac (arrowhead in C,C'). The overlap of Dac and Hth is yellow.
