[Use of a genetic system of the chimeric protein P-Ph in the repression of gene transcription of the leg-arista-wing complex in Drosophila].
Preliminary analysis of the leg-arista-wing complex (lawc) gene region in the corresponding mutants revealed P element insertion in the transcribed region of this locus. To demonstrate the main role of P element insertion in the complex pleiotropic phenotypic manifestation of the lawc gene, a system using P-Ph chimeric protein and based on the P-mediated repression of the lawc in vivo transcription was applied. As a result, extreme lawc-mutant phenotypes were obtained and examined. The P-Ph-mediated decrease of the level of the lawc gene transcription was also demonstrated.
