[Creation of a convenient vector for transformation of Drosophila with functional FRT-pFRT sites].
Modification of Drosophila transformation vector pCaSper3 with the P element was used to construct a new vector, pFRT. The vector contains two tandem FRT sites flanked with several unique restriction sites and separated by a polylinker of five restriction sites, and allows easy cloning of DNA fragments between or close to the FRT sites. FRT-mediated excision of DNA sequences cloned between the FRT sites was demonstrated in vivo. The vector was proposed for molecular genetic studies of the position effect variegation, structural and molecular organization of Drosophila polytene chromosomes, etc.
