Fig. 1. Posterior localization of cad mRNA. (A) Nvit cad is posteriorly localized in the ovary and early embryo. (B) Nvit cad localization in later stage follicles prior to nurse cell degeneration. (C,D) mRNA localizes to the oosome in freshly laid embryos. (E,F) A posterior-to-anterior Nvit cad mRNA gradient forms. (G) This gradient is also present during early zygotic transcription 2-3 hours after egg laying. (H) In Drosophila, cad is found throughout the early embryo. oc, oocyte; fc, follicle cells; nc, nurse cells.
