Expression of aopScer\UAS.cRa, driven by Scer\GAL4slbo.2.6, weakly enhances border cell migration defects in slbo01310 egg chambers, while expression of aopACT.Scer\UAS (also driven by Scer\GAL4slbo.2.6) strongly enhances this phenotype.
The border cells fail to migrate in the slbo01310 jing22F3 double mutant background, although the border cells are still present. Border cell migration is rescued in slbory8/slbo01310, slbo01310/slbo01310 or slbory7/slbo01310 egg chambers when jinghs.PL is expressed using a 1 hour heat shock (and then the flies are kept at 18oC for 20 hours to allow migration to occur). jinghs.PL does not rescue the border cell migration defects of slbo01310/slboe7b.
The sterility and abnormal border follicle cell migration phenotype of slbo01310 females is suppressed when AblEP3101, Hsp27EP329 or α-AdaptinEP2519 is expressed under the control of Scer\GAL4slbo.2.6. The border follicle cell migration phenotype of slbo01310 females is suppressed by EP2585EP2585 both in the absence of a Scer\GAL4 driver, and more strongly in the presence of Scer\GAL4slbo.2.6.
