Recombination in the green-to-red reporter strain, vc2. A)-C) uninjected embryos (shown at 18-somite stage) express GFP strongly (B) but do not express DsRed (C). D)-F) Injection of messenger RNA encoding codon-optimized phiC31 integrase (PhiC31o) induces widespread transgene recombination and expression of DsRed. (Due in part to significant maternal GFP expression, GFP signal is not seen to diminish.)
