Localization ofbicoidmRNA to the anterior of theDrosophilaoocyte is essential to produce the Bicoid protein gradient that patterns the anterior-posterior axis of the embryo. Previous studies have characterized a microtubule-dependent pathway forbicoidmRNA localization during midoogenesis, whenbicoidfirst accumulates at the anterior. We show that the majority ofbicoidis actually localized later in oogenesis, when the only known mechanism for mRNA localization is based on passive trapping. Through live imaging of fluorescently tagged endogenousbicoidmRNA, we identify a temporally distinct pathway forbicoidlocalization in late oocytes that utilizes a specialized subpopulation of anterior microtubules and dynein. The directional movement ofbicoidRNA particles within the oocyte observed here is consistent with dynein-mediated transport. Furthermore, our results indicate that association ofbicoidwith the anterior oocyte cortex is dynamic and support a model for maintenance ofbicoidlocalization by continual active transport on microtubules.
