1) Chimeric gene for conferring on plants increased tolerance to a herbicide. 2) It comprises, in the direction of transcription, a promoter region, a transit peptide region, a sequence encoding the tolerance to glyphosate and a polyadenylation signal region, characterised in that the promoter region consists of at least one histone plant gene promoter which allows the expression of the protein for tolerance to herbicides in the glyphosate accumulation regions. 3) Production of glyphosate-tolerant plants. |
