Fig. 3. Wg signaling regulates the expression of Snail family factors.
(A) A clone of actin-wg in adult RR eye induces ectopic
expression of the transcriptional reporter (arrow). (B-B") A
clone of actin-wg (red) in Cir1 pupal eye (
32 hours APF) showing
ectopic expression of the transcriptional reporter (green).
(C-C") An actin>Gal4;
UAS-
Arm clone in pupal retina (32 hours APF)
marked by GFP (green) shows ectopic Escargot (red) non-autonomously.
(D-D") A large dsh[V26] clone in the pupal eye periphery
(32 hours APF) marked black by the absence of GFP. Peripheral Esg (red)
is almost entirely abolished. The faint lattice of staining is the incipient
Esg expression in the main retina 2°/3° pigment cells - this is not Wg
dependent. (E-E") An arr[2] clone in the pupal eye edge
(32 hours APF) marked black by the absence of GFP. Escargot expression
(red) is lost in the clone. (E'') A merge of the two with an additional
stain for Cut (blue). The arrowhead indicates a cone cell that would normally
express Escargot but fails to do so in the clone.
