Construct: 5' regulatory region deletion between nucleotides -1855 and -495, and the region between nucleotides -2690 and -1868 in reversed orientation.
Deletion of sequences from -1855 to -495bp, with the region between -1868 and -2690bp 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}.
