Blocked endocytotic uptake by the oocyte causes accumulation of vitellogenins in the haemolymph of the female-sterile mutants quitPX61 and stand stillPS34 of Drosophila.

Abstract excerpt

The developmental lesions in two female-sterile mutants, quitPX61 (qui) and stand stillPS34 (stil), of Drosophila have been analysed. Previtellogenic development is normal in mutant qui ovarioles but, during vitellogenic stages, only small quantities of yolk accumulate in the oocyte. The nurse-cell cytoplasm does not stream into the oocyte. However, the follicle cells continue their developmental program and...
