Dynamic Rewiring of the Drosophila Retinal Determination Network Switches Its Function from Selector to Differentiation
Figure 2
So regulates Ey expression anterior and posterior to the morphogenetic furrow.
(A) so3 null clones, induced by hs-flp 72 hrs AEL showing So (green), Ey (red), and ELAV expression (blue); the yellow arrowhead marks the morphogenetic furrow, and the blue arrow indicates an anterior clone. (A′) Grayscale image of So expression, green in A; loss of So expression marks the clones. (A″) Grayscale image of Ey, red in A. (B) F2-Gal4 drives expression of soRNAi (VDRC transformant KK108128). (B′) Grayscale image of ELAV expression, green in B, marks differentiating photoreceptors. (B″) Grayscale image of Ey expression, red in B. Ey derepression posterior to the furrow matches previously described pattern of F2-Gal4 expression.
