3.To address the potential safety problem of genetically modified (MG) plants, a novel system pLFHFGN based on site-specific recombinase FLP was constructed. All foreign genes, including a FLP recombinase gene driven by heat-shock promoter Hsp18.2 (Hsp18.2-FLP-Nos) and a GUS:NPTII fusion gene under the control of CaMV 35S promoter, were flanked by two loxFRT recognition sites.
