Abstract: Compositions for the targeted integration of nucleotide sequences into a plant are provided. Plants and plant cells having multiple transfer cassettes stacked at precise locations in the genome of a plant or plant cell are provided. In specific embodiments, the plant or plant cell comprises at least two transfer cassettes. The first transfer cassette comprises a first nucleotide sequence of interest flanked by a first and a second recombination site, wherein the first and the second recombination sites are non-identical. The second transfer cassette comprises a second nucleotide sequence of interest flanked by the second recombination site and a third recombination site, wherein the third recombination site is non-identical to the first and said second recombination site.

Abstract: Methods for the targeted integration of nucleotide sequences into a plant are provided. Transfer cassettes comprising nucleotide sequences of interest flanked by non-identical recombination sites are used to transform a plant comprising a target site. The target site contains at least a set of non-identical recombination sites corresponding to those on the transfer cassette. Exchange of the nucleotide sequences flanked by the recombination sites is effected by a recombinase.

Abstract: Methods and compositions for the stacking of multiple nucleotide sequences at precise locations in the genome of a plant or plant cell are provided. Specifically, transfer cassettes comprising nucleotide sequences of interest flanked by non-identical recombination sites are introduced into a plant comprising a target site. The target site contains at least a set of non-identical recombination sites corresponding to those on the transfer cassette. Exchange of the nucleotide sequences flanked by the recombination sites is effected by a recombinase. The transfer cassettes and target sites are designed so as to allow for the stacking or ordering of nucleotide sequences at precise locations in the plant genome.

Abstract: Methods to find optimal integration sites within a plant genome are provided. More particularly, a plant is transformed with a target site having an expression cassette comprising a nucleotide sequence operably linked to a promoter active in the plant. The target site is flanked by non-identical recombination sites. Transformed protoplast, tissues, or whole plants can be tested to determine the levels of activity of the inserted gene. By comparison of cellular activities of the gene in different insertion sites, preferred integration sites may be found wherein the gene is expressed at high or acceptable levels. These plants can then be utilized with subsequent retargeting techniques to replace the nucleotide sequence with other genes or nucleotide sequences of interest contained in a transfer cassette.

Abstract: This invention relates to plant breeding and the protection of plants from insects. More specifically, this invention includes novel transformation events of cotton plants comprising one or more polynucleotide sequences, as described herein, inserted into specific site(s) within the genome of a cotton cell. In highly preferred embodiments, said polynucleotide sequences encode “stacked” Cry1F and Cry1Ac lepidopteran insect inhibitory proteins. However, the subject invention includes plants having single cry1F or cry1Ac events, as described herein. Additionally, the invention is related to cotton plants derived from that transformation event and to assays for detecting the presence of the event in a sample. More specifically, the present invention provides DNA and related assays for detecting the presence of certain insect-resistance events in cotton. The assays are based on the DNA sequences of recombinant constructs inserted into the cotton genome and of the genomic sequences flanking the insertion sites.

Abstract: 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.
