Construct: 5' regulatory region deletion between nucleotides -2690 and -1868, and the region between nucleotides -1855 and -495 in reversed orientation.
Deletion of sequences from -2690 to -1868bp, with the region between -1855 and -495bp in reverse orientation relative to wild-type.
construct_comment: One of a series of constructs used for deletion analysis of the 5\' regulatory region of the yellow gene; see P{Car20y}.
