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.

10. A method for cleaving one or more EPSPS genes in a plant cell, the method comprising:
-
introducing into said plant cell one or more polynucleotides encoding a non-naturally occurring zinc finger protein (ZFP) that binds to a target site in an endogenous 5-enolpyruvyl shikimate-3-phosphate synthase (EPSPS) gene, wherein the zinc finger protein comprises the zinc finger domains set forth in any single row of Table A, said ZFP further comprising a nuclease cleavage domain which cleaves one or more EPSPS genes, expressing the one or more ZFPs in the cell, wherein the ZFPs cleave one or more EPSPS genes. - View Dependent Claims (11, 12, 13, 14)

15. A method for modulating expression of an EPSPS gene in a cell in a plant, the method comprising:
expressing in said cell one or more polynucleotides encoding a non-naturally occurring zinc finger protein (ZFP) that binds to a target site in an endogenous 5-enolpyruvyl shikimate-3-phosphate synthase (EPSPS) gene, wherein the zinc finger protein comprises the zinc finger domains set forth in any single row of Table A, said ZFP further comprising a transcriptional activator domain, wherein the ZFP binds to a target sight in the EPSPS gene, thereby increasing expression of the EPSPS gene. - View Dependent Claims (16)
