摘要:
Methods and compositions for altering a nucleotide sequence of interest in a plant is provided. The method involves introducing a chimeric oligonucleotide into a RNA residues with intervening DNA residues. The RNA blocks are homologous to a plant nucleotide sequence. The chimeric oligonucleotide is capable of folding to form a duplex oligonucleotide. The chimeric oligonucleotide is maintained within the nucleus of the plant whereby the alteration is introduced into the target sequences of the plant genome.

Methods and compositions for altering a nucleotide sequence of interest in a plant is provided. The method involves introducing a chimeric oligonucleotide into a plant cell, wherein the oligonucleotide comprises at least two intervening blocks of RNA residues with intervening DNA residues. The RNA blocks are homologous to a plant nucleotide sequence. The chimeric oligonucleotide is capable of folding to form a duplex oligonucleotide. The chimeric oligonucleotide is maintained within the nucleus of the plant whereby the alteration is introduced into the target sequences of the plant genome.
摘要:
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.
摘要:
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.
摘要:
Methods and compositions for the targeted integration of nucleotide sequences into a plant are provided. Particularly, the present invention is drawn to compositions comprising polynucleotide sequences having the following operably linked components: an intron, a nucleotide sequence of interest, and a terminator region, wherein the polynucleotide sequence comprises one or more recombination sites. The recombination sites are non-identical to one another and one of the recombination sites is contained within the intron.
