Construct: w expression is governed by a fragment of Dvir\en promoter extending from -2.9kb to -1.5kb upstream of the transcription start site.
construct_comment: Expression observed in homozygotes versus heterozygotes; tested for proximity dependence (transvection).
construct_comment: One of a series of constructs analyzed for effects of en sequences upon expression of the adjacent w+mC gene.
