Hippo pathway promotes JNK-dependent border cell migration in oogenesis. upd-Gal4 was used to overexpress or knockdown genes specifically in polar cells. (A) Stage-10 migration index for quantification of border cell migration. (B) Quantification of stage-10 migration index for the following genotypes: control (n = 43), upd > wts.RNAi (n = 109), and upd > wts.RNAi + pucā/+ (n = 109). (CāE) Compared with controls, knockdown of wts induced border cell migration defect (D) was rescued by deleting one copy of puc (E). (Magnification: 20Ć.) Genotypes: (C) upd-Gal4, UAS-GFP/+; (D) upd-Gal4, UAS-GFP/+; UAS-wts.RNAi; and (E) upd-Gal4, UAS-GFP/+; UAS-wts.RNAi/pucE69.
