In embryos, lower levels of expression observed in first 3 (anterior) stripes; in subsequent stripes, expression in even-numbered stripes is higher than that in odd-numbered stripes. Note: Results using assay for β-gal activity differ from those detecting the β-gal RNA. The stripe pattern persists into late stages of embryogenesis in the former case, but not in the latter.
construct_comment: Expression observed in homozygotes versus heterozygotes; tested for proximity dependence (transvection).
construct_comment: One of a series of constructs used to characterize en regulatory elements contained within the first intron.
construct_comment: One of a series of constructs analyzed for effects of en sequences upon expression of the adjacent w+mC gene.
construct_comment: One of several constructs designated P{en2}, all of which contain 2.4kb of en 5\' flanking sequences and en intron 1 sequences.
