Mutation within the P-element repressor coding sequence (nucleotide substitution: T1100A, amino acid replacement: V297E).
P\TSal-M11-1 does not show P-element dependent silencing (PDS) of the w marker in the P{lacW}ciDplac insertion (in contrast to its progenitor, P\TSal), with flies carrying both P{lacW}ciDplac and P\TSal-M11-1 in a w[-] background having red eyes.
P\TSal-M11-1 does not cause P-element dependent silencing of the w marker in the P{hsp26-pt-T}ci2-M1021.R insertion.
P\TSal-M11-1 does not suppress the variegation of the w marker that is seen in the P{hsp26-pt-T}39C-12 insertion line.
