Figure 2.

Genomic fragments from the wings-up A region and its reporter expression domains. (A) Extent in kilobases of major genomic fragments tested. (B) Expression domains of the only fragment that yielded expression, the 4.7 kb. Images of the expression in the embryo (e), dorsal vessel of the larvae (dv), adult abdominal muscles (ab), adult tergal depressor of the trochanter (TDT), dorsolongitudinal muscles (DLM), somatic larval muscles (lm), and larval gut (lg). (C) Genomic subfragments tested for reporter expression. Numbers indicate size in kilobases.
