Fig. 1. Molecular map of the pros54 genomic region. (A) Position of the
pros54, Vha M9.7-2 and CG7181 genes according to GadFly.
Arrows show the location and the direction of these genes. The triangle labels
the site of P-lacW0554/18 insertion. The E and PIR PCR
primers used to screen for genomic deletions are indicated in the upper part
of the figure. S, E and P are SacI, EcoRI and PstI
restriction sites, respectively. Numbers in parentheses give the
nucleotide-scale positions according to GadFly. (B) Extension of
Df(3L)pros54P(w+). (C) Restriction fragments used in
rescue experiments (see text).
