The product of the Drosophila gene Serrate acts as a short-range signal during wing development to induce the organising centre at the dorsal/ventral compartment boundary, from which growth and patterning of the wing is controlled. Regulatory elements reflecting the early Serrate expression in the dorsal compartment of the wing disc have recently been confined to a genomic fragment in the 5'-upstream region of the gene. Here we present data to suggest that this fragment responds to various positive and negative inputs required for the early Serrate expression. First, activation and maintenance of expression in the dorsal compartment of the wing discs of second and early third instar larvae depends on apterous, as revealed by reporter gene expression in discs either lacking or ectopically expressing apterous. Second, transcriptional downregulation during third larval instar is mediated by hiiragi. Finally, this regulatory element responds to Delta signalling in a nonautonomous way to maintain Serrate expression along the dorsal margin. The results clearly show that some of the previously described transactivators of Serrate protein expression, e.g. fringe, act on elements required for later aspects of Serrate expression.
