Figure 3.—
BEAFAB-KO flies have a rough-eye phenotype that is rescued by BEAF transgenes. Scanning electron micrograph of a BEAFAB-KO fly (left) shows that it has a rough-eye phenotype. Introducing a single copy of a gBF (not shown) or GFBF transgene (right) rescues this phenotype, resulting in wild-type eye morphology. BEAFA-KO flies do not have a rough-eye phenotype (not shown).
