Tóm tắt

AbstractEctopic eyes induced in a wing serve as a system for studying developmental plasticity in Drosophila. We used a set of chromosome deficiencies covering the second chromosome to ask whether there are dose-sensitive modifiers of the process. We identified three overlapping deletions showing the enlargement of ectopic eyes. The study of the genes localized in the region of interest suggests that the mutation in the sxc (super sex combs) gene (PcG group) is responsible for the observed phenotype.
