GENE TARGETING IN PLANTS USING DNA VIRUSES
First Claim
Patent Images
1. A method for modifying the genetic material of a plant cell, comprising:
- (a) introducing into the cell a virus nucleic acid comprising a donor sequence that is heterologous to the virus and is targeted to a first sequence that is endogenous to the plant cell; and
(b) inducing a double strand break at or near the sequence to which the donor sequence is targeted, wherein said double strand break is generated by an endonuclease targeted to a second endogenous plant sequence at or near the first sequence that is targeted by the donor sequence,wherein homologous recombination occurs between the first endogenous plant sequence and the donor sequence.
