The evolution of dorsoventral patterning in insects

The gene regulatory network (GRN) underpinning dorsal-ventral (DV) patterning and gastrulation of the/Drosophila/ embryo is among the most thoroughly understood GRNs, making it an ideal system for comparative studies seeking to understand the evolution of development. With the emergence of widely applicable techniques for testing gene function, species with sequenced genomes, and multiple tractable species with diverse developmental modes, a phylogenetically broad and molecularly deep understanding of the evolution of DV axis formation in insects is feasible. I will review recent progress made in this field with particular focus on the evolution of EGF , Toll and BMP signaling.
