Fig. 1. Mapping of vri 5' end and generation of deletion alleles by
P-element mutagenesis. The position of the vri alleles and
the extent of the deletions generated are shown. The localization of the
vri cDNAs, the other described loci, the putative GadFly genes and
the BDGP cDNAs are presented. The positions of the genomic (1, 2, 3, 4) and
PlacW primers used for PCR amplification are shown (arrows).
vri1 (cDNA3.8) and vri2 (cDNA3.3) are the two types of cDNAs
used for UAS constructs. DS00714 distal end of a P1 phage isolated by the
BDGP, DM194B8, T7 end and DM77B6, SP6 end of two cosmids isolated by the
European Drosophila Mapping Consortium.
