Abstract
The present invention refers to a plant or plant part comprising a polynucleotide encoding a wildtype or mutated cellulose synthase (CESA) polypeptide, the expression of said polynucleotide confers to the plant or plant part tolerance to CESA-inhibiting herbicides, such as azines.
Claims18
A plant or plant part comprising a polynucleotide encoding a wildtype or mutated cellulose synthase (CESA) polypeptide, a variant thereof, the expression of said polynucleotide confers to the plant or plant part tolerance to CESA-inhibiting herbicides, wherein the variant comprises on or more of the following motifs:
- i)
- Motif 1a:
- (SEQ ID NO:
- 78)
- [V/I][A/V]G[V/I/F][S/T][Y/D/N/A]A[V/I/L][N/S/G]
- [S/N]G[Y/F/E][Q/D/G/E/H][S/A]WG[P/A]L[F/M/L]G
- [K/R][L/V][F/L]F,
- wherein the amino acid at position 5, 16, 17, and/or 20 within said motif is substituted by any other amino acid;
- ii)
- Motif 2a:
- (SEQ ID NO:
- 81)
- [V/L/I]W[S/A][V/A/I]LL[A/S]S[I/F/V][F/L][S/T][L/V]
- [L/M/V/I]WV[R/K][I/V][N/D]PF,
- wherein the amino acid at position 8 and/or 11 within said motif is substituted by any other amino acid.
A method for controlling weeds at a locus for growth of a plant, the method comprising:
- (a) applying an herbicide composition comprising CESA-inhibiting herbicides to the locus;
- and (b) planting a seed at the locus, wherein the seed is capable of producing a plant that comprises in at least some of its cells a polynucleotide operably linked to a promoter operable in plant cells, the promoter capable of expressing a wildtype or mutated CESA polypeptide encoded by the polynucleotide, the expression of the wildtype or mutated CESA polypeptide conferring to the plant tolerance to CESA-inhibiting herbicides, wherein the mutated CESA polypeptide comprises one or more of the following motifs:
- i)
- Motif 1a:
- (SEQ ID NO:
- 78
- [V/I][A/V]G[V/I/F][S/T][Y/D/N/A]A[V/I/L][N/S/G]
- [S/N]G[Y/F/E][Q/D/G/E/H][S/A]WG[P/A]L[F/M/L]G
- [K/R][L/V][F/L]F,
- wherein the amino acid at position 5, 16, 17, and/or 20 within said motif is substituted by any other amino acid;
- or
- ii)
- Motif 2a:
- (SEQ ID NO:
- 81)
- [V/L/I]W[S/A][V/A/I]LL[A/S]S[I/F/V][F/L][S/T][L/V]
- [L/M/V/I]WV[R/K][I/V][N/D]PF,
- wherein the amino acid at position 8 and/or 11 within said motif is substituted by any other amino acid.
The method of claim 10, wherein herbicide composition is applied to the weeds and to the plant produced by the seed.
The method according to claim 10, wherein the CESA-inhibiting herbicide comprises a compound having the Formula (I):
A method of producing a progeny plant having tolerance to CESA-inhibiting herbicide, the method comprising:
- crossing a first CESA-inhibiting herbicide-tolerant plant with a second plant to produce a CESA-inhibiting herbicide-tolerant progeny plant, wherein the first plant and the progeny plant comprise in at least some of their cells a polynucleotide operably linked to a promoter operable in plant cells, the promoter capable of expressing a wildtype or mutated CESA polypeptide encoded by the polynucleotide, the expression of the wildtype or mutated CESA polypeptide conferring to the plant tolerance to CESA-inhibiting herbicides.
The method of claim 16, wherein the plant product is fodder, seed meal, oil, or seed-treatment-coated seeds.
The plant product of claim 18, wherein the product is fodder, seed meal, oil, or seed-treatment-coated seed.
