1. A method for stimulating homologous recombination in the genome of a plant cell, the method comprising the step of:
- introducing a zinc finger nuclease (ZFN) into the plant cell in the presence of a DNA segment in the plant cell, wherein the DNA segment comprises at least one target site in an 5-enolpyruvyl shikimate-3-phosphate synthase (EPSPS) gene, wherein said target site comprises any one of SEQ ID NO;
141-153, wherein the ZFN cleaves the DNA segment and stimulates homologous recombination, wherein the ZFN comprises a non-naturally occurring zinc finger protein (ZFP) that binds to said target site in the EPSPS gene, wherein the ZFP comprises the recognition helix regions designated and ordered as set forth in any single row of Table A.

Abstract
The present disclosure relates to engineered zinc finger proteins that target 5-enolpyruvyl shikimate-3-phosphate synthase (EPSPS) genes in plants and methods of using such zinc finger proteins in modulating gene expression, gene inactivation, and targeted gene modification. In particular, the disclosure pertains to zinc finger nucleases for targeted cleavage and alteration of EPSPS genes.
