Mechanisms of positional signalling in the developing eye of Drosophila studied by ectopic expression of sevenless and rough.

Journal of cell science. Supplement - 1 Jan 1990

Hafen E, Basler K

Abstract excerpt

In the developing eye of Drosophila cell fate is controlled by a cascade of inductive interactions. Little is known about how the specificity of positional signalling is achieved such that directly adjacent progenitor cells reproducibly choose distinct developmental pathways. The determination of the R7 photoreceptor in each ommatidium depends on the presence of the sevenless protein which acts as a receptor for...
