Chimeric gene for conferring to plants an increased tolerance to a herbicide having as its target EPSPS comprises, in the direction of transcription, a promoter region, a transit peptide region, a coding sequence for glyphosate tolerance and a polyadenylation signal region, wherein the transit peptide region comprises, in the direction of translation, at least one transit peptide of a plant gene encoding a plastid-localised enzyme, a partial sequence of the N-terminal mature part of a plant gene encoding a plastid-localised enzyme and then a second transit peptide of a plant gene encoding a plastid-localised enzyme. Production of glyphosate-tolerant plants is disclosed.
