Abstract

Putative cis-acting regulatory elements immediately upstream of theGld promoter were identified by comparative analysis of three Drosophila species. A 509 bp region containing these elements and the Gld promoter region was shown to confer tissue-specific regulation to a reporter gene similar to the pattern observed for Gld mRNA and protein. A dispersed repeat with a core motif of TTAGA was also capable of directing the expression of a reporter gene to several epidermally derived tissues in which GLD is normally expressed. These tissues include male and female somatic reproductive organs. The TTAGA elements and a palindromic element act antagonistically to block expression of reporter gene in some tissues. Previously reported mutations of the heat shock response element resulted in the creation of three TTAGA elements. This mutated hsp70 promoter directs expression of a reporter gene to many of the same tissues as does the Gld TTAGA elements. We have found TTAGA elements near the promoter of two other genes which show an identical expression pattern in the male ejaculatory duct as Gld and the mutant hsp70.
