Fig. 6. Ectopic expression of DMyb induces small increases in apoptosis in wing discs. A low level of apoptosis was detected with in a control wing disc (A). Small increases were observed when en-Gal4 was used to drive ectopic expression of either DMyb (not shown) or
DMyb (B) in the posterior compartment, and when sd-Gal4 was used to drive ectopic expression of DMyb (C). Higher levels of apoptosis were observed when sd-Gal4 was used to drive
DMyb expression (D). Results were similar with Acridine Orange and TUNEL staining. The former is shown in A-C and the latter in D. Scale bar: 0.05 mm.
