Imprecise excision of the P{PZ}CtBP03463 element, resulting in a deletion of nucleotides 2990-3445 (coordinates relative to GenBank accession number X52187.1) which deletes sequences encoding Su(var)3-7 amino acids 896 to 1020.
Imprecise excision of the P{PZ}CtBP03463 element, resulting in a deletion of nucleotides 2610-2622 (coordinates relative to GenBank accession number X52187.1).
When P{P-Sal}89D is present, the w gene of the P{lacW}ciDplac insertion variegates, resulting (in a w- background) in an eye that is mostly white with a few patches of red ommatidia. This P-element-dependent silencing of P{lacW}ciDplac is dominantly suppressed by Su(var)3-7P12.
