Fig. 8. dan mutant phenotype. (A) Antenna from a danr^ems3 homozygous mutant. Note the single ectopic bristle in the third segment (arrow). (B) Antenna from a fly expressing dan double stranded RNA under Dll^Gal4 control. Arrows indicate ectopic bristles. (C) Eye-antenna disc from a larva expressing dan double stranded RNA under dpp^Gal4 control (green). Dan protein (red) was reduced. Danr protein (blue) was unaffected. Dan and Danr expression in the boxed area is shown separately on the right.
