  • Patent number: 5792930
    Abstract: The present invention relates to a chimeric gene for conferring to plants an increased tolerance to a herbicide. This chimeric gene comprises, in the direction of transcription, a promoter region, a transit peptide region, a sequence encoding glyphosate tolerance and a polyadenylation signal region, wherein the promoter region consists of at least one promoter of a plant histone gene enabling the expression of the herbicide tolerance protein in the regions of glyphosate accumulation. The present invention further provides vectors containing the present chimeric genes, of glyphosate-tolerant plants.

  • Patent number: 5773698
    Abstract: Chimeric gene which is usable for endowing plants with resistance to a herbicide based on 3,5-dihalo-4-hydroxybenzonitrile, comprising at least one gene coding for resistance to this herbicide, a foreign promoter and, optionally, a polyadenylation signal region, wherein the promoter originates from a gene which is naturally expressed in plant cells and is chosen from the group comprising the promoter of the 35 S RNA for cauliflower mosaic virus (CaMV 35S) and the promoter of the small subunit (SSU) of sunflower (Helianthus annuus) ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO).
