Description

lacZ gene expression is driven by a 750bp EcoRI fragment from vg intron 2 (the vg intron 2 enhancer element) that shares sequence homology with the same fragment from Dvir\vg.

lacZ expression is governed by the wild-type vg second intron D/V boundary enhancer element.

Additional Information
Statement
Reference

Ecol\lacZvg.int2.1 transcript is expressed starting at the beginning of the second larval instar in the wing disc. Ecol\lacZvg.int2.1 expression is observed along the D/V boundary of the wing disc, as well as along the part of the A/P boundary that lies within the wing pouch.

Expression restricted to a stripe of cells spanning the dorsal/ventral boundary in the wing and haltere discs. No expression observed in any other larval or embryonic tissues. Earliest expression in second instar wing disc is weak and diffuse; by late second instar has resolved into a broad stripe along the D/V boundary.
