Figure 3.

BrC-Z1 is up-regulated in both usp² and usp³ clones. Clonal studies for usp² in a wing disk (A–C) and in an eye disc (G–I); clonal studies for usp³ in a wing disc (D–F) and in an eye disc (J–L) stained with anti-myc (Texas red) and with anti-BrC-Z1 antibodies (FITC). (A–C) The wing disk is situated anterior to the upper left, ventral to the upper right. Magnification is at 40×. (D–F) Anterior is to the left, ventral to the top. Magnification is at 20×. (G–I) The eye disc has its anterior to the bottom left. Magnification is 40×. (J–L) Anterior is to the upper left. Magnification is 40×. Cells with strong myc staining are in a +/+ background; cells homozygous for usp mutants are myc negative and are marked with dotted lines. (H, K) The morphogenetic furrow is marked with an arrow.
