Fig. 2. Differential sensitivity of compartmentalization and Wg expression to
Notch. (A-C) Nts wing imaginal discs, from animals
cultured at 18°C during embryonic development, and then at (A) 18°C,
(B) 22°C or (C) 29°C during larval development. At 22°C, in some
instances (B, arrow), the DV interface is obviously disturbed despite
continuous Wg expression. At 18°C, the DV interface is normal or subtly
disturbed, and Wg expression is normal, whereas, at 29°C, the DV interface
is grossly disturbed, and Wg is not expressed.
