Figure 2

A simplified representation of the genetic network underlying dorsoventral polarity ( pip ) and DA-formation (br) during D. melanogaster oogenesis. Input comes from two main signaling pathways, EGFr and Dpp, providing dorsoventral and anteroposterior information, respectively, and results in the specification of domains on the epithelium expressing pip and br.
