Figure 6.

The expression of single-minded, ventral nervous system defective and short gastrulation in wild type and Scutoid mutant eye-antennal imaginal discs. In situ hybridization analysis of sim (A and B), vnd (C and D) and sog (E and F). Neither sim nor vnd is expressed in w¹¹¹⁸ (A and C) or noc^Sco/+ (B and D) eye-antennal imaginal discs. sog is expressed only in the region that gives rise to the ocelli, and is found at similar levels in w¹¹¹⁸ (E) and noc^Sco/+ (F) eye imaginal discs.
