1. A plant or plant part comprising a polynucleotide encoding a mutated cellulose synthase (CESA) polypeptide, wherein expression of said polynucleotide confers to the plant or plant part tolerance to CESA-inhibiting herbicides, wherein the mutated CESA polypeptide comprises one or more of the following motifs:
i) Motif 1a:
| ||||||||
wherein the amino acid at position 5 within said motif is substituted by any other amino acid than S or T;
wherein the amino acid at position 16 within said motif is substituted by any other amino acid; and/or
wherein the amino acid at position 17 within said motif is substituted by any other amino acid than P or A;
ii) Motif 2a:
| ||||||||
wherein the amino acid at position 8 within said motif is substituted by any other amino acid; and/or
the amino acid at position 11 is substituted by any other amino acid,
wherein the mutated CESA polypeptide comprises an amino acid sequence having, over the full-length, at least about 80% sequence identity to SEQ ID NO: 49 or 55, and
wherein the amino acid sequence of the mutated CESA polypeptide differs from the wildtype amino acid sequence at one or more positions corresponding to positions 1009, 1010, 1052, and 1055 of SEQ ID NO: 1.
