摘要:
Compositions and methods for introducing a DNA of interest into a genomic target site are provided. In particular, the methods and compositions involve the use of a combination of target sites for two site specific recombinases and expression of a chimeric recombinase with dual target site specificity. Thus, the compositions comprise novel site-specific recombinases with specificities to multiple target sites, and nucleotide sequences and expression cassettes encoding these recombinases or target sites. The methods involve transforming a eukaryotic cell having target sites for the novel recombinase with a DNA of interest that is flanked by corresponding target sites. Expression of the recombinase results in integration of the DNA of interest into the genome of the cell. The compositions and methods of the invention have use in the construction of stably transformed eukaryotic cells, and in particular, plant cells. The methods result in the efficient targeted genomic integration of DNA by site-specific recombination.
