Fig. S1. Sensory precursors are affected by lack of Vnd. (A-D) Head flat preparations antibody double stained against Atonal (Ato) and Engrailed (En-LacZ in A,B; En-protein in C,D) at late stage 11. (A,B) In wildtype (wt), Ato is expressed in the precursors of the antennal dorsal organ (Dd9,11,12,13) positioned within the antennal appendage, and, by that stage, in Dv1, a precursor of the hypopharyngeal-/latero-hypopharyngeal organ (Urbach et al., 2003). (C,D) In vnd mutants (vnd-), Ato is normal in precursors of the dorsal organ, but often missing at the position of Dv1 and in its proneural cluster (25%, n=18). (D) In the individual shown, Ato is found in Dv1 on the left side (black arrowhead), but absent on the right side (white arrowhead). Orientation and abbreviations are as in former figures.
