ftz upstream sequences from -669 to -172bp, followed by ftz promoter sequences from -40 to +73bp are fused in frame to the lacZ coding sequence.
construct_comment: One of a series of sequential deletion constructs used to characterize the "zebra" enhancer element of ftz.Additional members listed under P{ftz5\'Δ669}.
