Wheat with reduced lipoxygenase activity
First Claim
1. A wheat plant comprising at least one mutation in an Lpx1 gene in at least one of a B or D genome, wherein the Lpx1 gene of the B genome is Lpx-B1.2, and the at least one mutation in the Lpx-B1.2 gene comprises a tryptophan substitution to a stop codon at amino acid position 510 (W510*) of SEQ ID No. 6, or a tryptophan substation to a stop codon at amino acid position 494 (W494*) of SEQ ID No. 6, or a guanine substitution to an adenine at nucleotide position 2691 of SEQ ID No. 4, and further wherein the Lpx1 gene of the D genome is Lpx-D1, and at least one mutation in the Lpx-D1 gene comprises a tryptophan substitution to a stop codon at amino acid position 494 (W494*) of SEQ ID No. 3, or a tryptophan substitution to a stop codon at amino acid position 81 (W81*) of SEQ ID No. 3, or a tryptophan substitution to a stop codon at amino acid position 101 (W101*) of SEQ ID No. 3, or a tryptophan substitution to a stop codon at amino acid position 517 (W517*) of SEQ ID No. 3, or a guanine substitution to an adenine at nucleotide position 1538 of SEQ ID No. 15.

Abstract
A series of independent human-induced non-transgenic mutations found at one or more of the Lpx genes of wheat; wheat plants having these mutations in one or more of their Lpx genes; and a method of creating and finding similar and/or additional mutations of Lpx by screening pooled and/or individual wheat plants. The wheat plants disclosed herein exhibit decreased lipoxygenase activity without having the inclusion of foreign nucleic acids in their genomes. Additionally, products produced from the wheat plants disclosed herein display increased oxidative stability and increased shelf life without having the inclusion of foreign nucleic acids in their genomes.
