Figure 2

Enhancer mapping within ss. The DNA scale is marked in kilobases. Above this scale are shown the ss transcribed region (exons are indicated as blue boxes; coding regions are dark blue, noncoding regions are light blue) and the locations of four ss mutants (A designates antennal transformations and B designates bristle reduction). The fragments tested for enhancer activity are indicated in red, and the expression patterns each drives are shown below for embryos (top), imaginal discs (middle) and for structures at the pupal stage (bottom). Embryonic expression is shown for only B6.9 and EX8.2. The expression patterns shown for EX6.5 are actually those of its P732 subfragment, which drives persistent, rather than transient, expression in the leg and antenna (see results). For all fragments, the embryonic and disc expression patterns shown correspond to patterns detected for the ss transcript (Duncan et al. 1998). Abbreviations: Ab (abdominal tergite), An (antenna), E (embryo), L (leg), P (maxillary palp), W (wing).
