Role of programmed cell death in patterning the Drosophila antennal arista.

Abstract excerpt

Programmed cell death is a critical process for the patterning and sculpting of organs during development. The Drosophila arista, a feather-like structure at the tip of the antenna, is composed of a central core and several lateral branches. A homozygous viable mutation in the thread gene, which encodes an inhibitor of apoptosis protein, produces a branchless arista. We have found that mutations in the...
