<p>1) Chimeric gene for conferring on plants increased tolerance to a herbicide against EPSPS. 2) It comprises, in the direction of transcription, a promoter region, a transit peptide region, a sequence encoding tolerance to glyphosate and a polyadenylation signal region, characterised in that the transit peptide region comprises, in the direction of translation, at least one transit peptide from a plant gene encoding a plastid-localised enzyme, a portion of the sequence of the mature N-terminal portion of a plant gene encoding a plastid-localised enzyme, then a second transit peptide from a plant gene encoding a plastid-localised enzyme. 3) Production of glyphosate-tolerant plants.</p> |
