Molecular nature and mode of action of spatial information responsible for organizing cell and body patterns in Drosophila.


Much of our work has been concerned with understanding how the global body pattern is organized by the anterior, posterior, and terminal determinant systems laid down in the egg during oogenesis. More recently, we have begun to examine spatial signaling which controls growth and patterning in cells giving rise to the adult appendages. In both cases, the general approach has been to identify putative signaling molecules, as well as receptors and other cellular components involved in responding to these signals, and then to manipulate these gene products by altering their structures or patterns of expression in vivo. Such experiments indicate in molecular terms what spatial information is, how it arises, and how it governs pattern.
