Abstract
The present invention relates Beta vulgaris plants or plant parts having a mutated endogenous acetolactate synthase (ALS) protein comprising at position 371 an amino acid different than aspartate (D). Such plants are characterized in having increased tolerance to ALS inhibitor herbicides. The invention further relates to methods for generating such plants as well as methods for identifying such plants.
Claims15
A Beta vulgaris plant, plant part, or plant population comprising, expressing, or capable of expressing a mutated endogenous acetolactate synthase (ALS) protein or a polynucleic acid encoding a mutated endogenous acetolactate synthase (ALS) protein comprising at position 371 an amino acid different than aspartic acid (D).
A method for identifying a Beta vulgaris plant or plant part, comprising screening for the presence in an ALS protein of an amino acid at position 371 which is different than aspartic acid (D), or screening for the presence of a codon encoding an amino acid in an ALS protein at position 371 which is different than aspartic acid (D).
A method for generating a Beta vulgaris plant or plant part, comprising mutating in the genome of a plant or plant part an endogenous ALS allele resulting in an ALS allele encoding an ALS protein comprising at position 371 an amino acid different than aspartic acid (D) or introducing in the genome (and expressing) of a plant or plant part a polynucleic acid encoding a mutated endogenous ALS protein comprising at position 371 an amino acid different than aspartic acid (D).
