Table 1. Summary of directions of two types of cargoes (Golgi units and Staufen RNP particles) at different ring canals.

Golgi units are labeled with RFP-Golgi [44] and osk/Staufen RNP particles are labeled with Staufen-SunTag [69] driven by nos-Gal4-VP16. Number of events are divided into two groups: “towards the oocyte” (moving towards the posterior) and “away from the oocyte” (moving towards the anterior). Highest directionality of both Golgi and osk/Staufen transport was observed in the nurse cell-oocyte ring canals.
