Fig. 5. bwk, shark and Jun interactions in oogenesis. (A,B) UAS-shark⁺ suppresses the bwk^151/8482 phenotype when expressed in stretch-cells. (A) DIC image of bwk^151/8482 DA phenotype. (B) DIC image of UAS-shark⁺ mediated suppression of bwk^151/8482 DA phenotype: DAs are longer and more tube-like. (C,D) Jun expression is unchanged in bwk. (C) Image of a wild-type stage-10 egg chamber showing immunofluorescence of the Drosophila Jun pattern in follicle cells. (D) Merged confocal image showing anti-Jun staining in a stage 10 egg chamber with a large shark clone (GFP-negative cells) covering most of the anterior follicle cells, including the stretch and DA-forming cells. Jun expression is unchanged.
