Mutated protoporphyrinogen ix oxidase (ppx) genes

Abstract

Provided are compositions and methods relating to gene and/or protein mutations in transgenic or non-transgenic plants. In certain embodiments, the disclosure relates to mutations in the protoporphyrinogen IX (PPX) gene. In some embodiments the disclosure relates to plants that are herbicide resistant.

1 . A non-transgenic plant cell comprising a mutated protoporphyrinogen IX oxidase (PPX) gene, wherein said gene encodes a protein comprising a mutation at one or more amino acid positions corresponding to a position selected from the group consisting of 52, 85, 105, 111, 130, 139, 143, 144, 145, 147, 165, 167, 170, 180, 185, 192, 193, 199, 206, 212, 219, 220, 221, 226, 228, 229, 230, 237, 244, 256, 257, 270, 271, 272, 305, 311, 316, 318, 332, 343, 354, 357, 359, 360, 366, 393, 403, 424, 426, 430, 438, 440, 444, 455, 457, 470, 478, 483, 484, 485, 487, 490, 503, 508 and 525 of SEQ ID NO: 1 or wherein said gene encodes a protein comprising a mutation at one or more amino acid positions corresponding to a position selected from the group consisting of 58, 64, 74, 84, 93, 97, 98, 101, 119, 121, 124, 139, 150, 151, 157, 164, 170, 177, 187, 188, 195, 214, 215, 229, 230, 271, 274, 278, 283, 292, 296, 307, 324, 330, 396, 404, 406, 410, 421, 423, 434, 447, 448, 449, 451, 454, 465, 470 and 500 of SEQ ID NO: 9.
