Df(2L)BSC103 was isolated as a FLP recombinase-induced recombination event
involving PBac{WH}f05122 and P{XP}d00641. The deletion was isolated as a
chromosome lacking miniwhite markers in progeny of P{hsFLP}1, y1 w1118;
PBac{WH}f05122/ P{XP}d00641 males crossed to w1118; P{w+mC=hs-hid}2,
wgSp-1/CyO females. These males were heat shocked as larvae as described
in Parks et al., Nature Genetics 36: 288-292, 2004 (FBrf0175003). This
cross and crosses in preceding and succeeding generations maintained the
original genetic background of the Exelixis insertion stocks (Thibault et
al, Nature Genetics 36: 283-287, 2004; FBrf0175002). The recombination
event generated the genetic element P+PBac{XP5.WH5}BSC103 from the segment
of PBac{WH}f05122 to the left of its FRT site and the segment of
P{XP}d00641 to the right of its FRT site. Its presence was verified using
the PCR methods and primers described in Parks et al. Exelixis, Inc.
determined the insertion site of PBac{WH}f05122 to be at Release 3 genomic
coordinate 21491266 on chromosome arm 2L and the insertion site of
P{XP}d00641 to be at Release 3 genomic coordinate 21509695 on arm 2L. The
Gene Disruption project determined the insertion site of P{XP}d00641 to be
at Release 3 genomic coordinate 21509890 on arm 2L. The cytological
breakpoints of Df(2L)BSC103 predicted from these coordinates are
39E6;39E7. Df(2L)BSC103 fails to complement P{PZ}cul-202074.
