Drives expression at all stages in a broad band centered on the dorsal midline.
drives expression in the dorsal ectoderm of the embryo; expression is also observed in other tissues at later stages.
Expression in the larval third in is observed in the promixmal-most part of the presumptive notum in the wing disc, and in the salivary gland.
drives expression in lateral mesothoracic tergum primoridum (presumptive notum); expression is driven only in the disc proper, and not in the peripodial epithelium. Expression begins early in the third larval instar.
Expression is driven in a wide dorsal stripe from the posterior head through the thorax and abdomen of larvae, pupae, and adults. In adults, the thoracic stripe is bounded on each side by the dorsocentral and postscutellar bristles.
In adults, y+ phenotype observed in a dorsal band along the length of the body, excluding the terminalia. Observed as adult phenotype; expression assumed to be earlier.
