WebThe efficacy of this system was examined using the FRT site-flanked genes HSP104, URA3 and GFP. The pre-excision frequency of this system, which might be caused by the basal activity of the GAL1 promoter or by spontaneous recombination between FRT sites, was detected ca. 2% under the non-selecting condition. WebClonal induction with the latter method occurs at relatively low frequencies making this method laborious. The introduction of the yeast FRT System/FRT site-directed recombination system to Drosophila has made generating loss-of-function mosaic clones simple and easy.
