seven in absentia, a gene required for specification of R7 cell fate in the Drosophila eye.

Cell - 2 Nov 1990

Carthew R W, Rubin G M

Abstract excerpt

Signals from directly adjacent cells are critical for the development of the R7 photoreceptor cell in the Drosophila eye. We have identified a gene, seven in absentia (sina), for which loss of function results in the R7 precursor cell adopting the fate of a nonneuronal cell type. Function of the sina gene is required only in R7 for correct R7 cell development. The sina transcription unit is located within the...
