Abstract
Methods and compositions using populations of randomized modified FRT recombination sites to identify, isolate and/or characterize modified FRT recombination sites are provided. Kits comprising the library populations of FRT sites are also provided, as are methods to make a library of modified FRT recombination sites. The recombinogenic modified FRT recombination sites can be employed in a variety of methods for targeted recombination of polynucleotides of interest.

1-15. (canceled)
A plant cell having stably incorporated into its genome at least a first nucleotide sequence of interest flanked by a first and a second recombination site, wherein said first and said second recombination sites are dissimilar and non-recombinogenic with respect to one another;
- such that the genome of the plant cell comprises in the following order the first recombination site, the first nucleotide sequence of interest, and the second recombination site, wherein said first and said second recombination sites are selected from the group consisting of FRT1 (SEQ ID NO:39) and FRT87 (SEQ ID NO:24).
