| Abstract: | We examine the effect of mutations in theextramacrochaetae (emc) gene on the positioning of macrochaetes on the notum ofDrosophila. We show that, inemc mutants, most of the precursor cells appear earlier than in wild-type individuals, consistent with an antagonizing effect ofemc on the action of the proneural genesachaete andscute. We also show that reducingemc function affects the position of three bristles and/or of their precursors, but has no marked effect on the positioning of the other bristles. |
