  • Publication number: 20180251778
    Abstract: The present invention relates to the field of plant transformation with genes conferring tolerance to glyphosate. The invention particularly relates to a maize (corn) plant transformed with a gene encoding an EPSPS providing the plant tolerance to an application of glyphosate under conditions where this herbicide is effective in killing weeds. The invention particularly concerns an elite transformation event VCO-Ø1981-5 comprising the gene construct and means, kits and methods for detecting the presence of the said elite event.

  • Patent number: 7094952
    Abstract: The subject of the present invention is a method for obtaining transgenic plants expressing a protein with H2O2 producing activity, which comprises the following steps of: (a) transforming plant cells with Agrobacterium rhizogenes containing a vector carrying a gene encoding a protein producing H2O2 in a context which allows its expression in the plant; (b) selecting the transformants which contain and express this gene, by a peroxidase-based colorimetric test; (c) regenerating the plants from the roots selected and monitoring the expression of the plantlets obtained by a peroxidase-based colorimetric test; (d) sorting according to phenotype and optionally carrying out the molecular analysis of the progeny of the transgenic plants, allowing the selection or the confirmation of transgenic plants obtained containing only the transgene and not the T-DNA specific to A. rhizogenes.
