  • eIF(ISO)4E PROTEIN VARIANTS FOR RESISTANCE TO MAIZE VIRAL DISEASES
    Publication number: 20260116930
    Abstract: The present invention relates to an eIF(iso)4E protein variant able to confer resistance to at least one maize virus, in particular able to confer resistance to Maize Lethal Necrosis Disease (MLND). Said protein variant comprises at least one mutation by comparison to the corresponding native maize eIF(iso)4E protein. The present invention also relates to a nucleic acid encoding at least one eIF(iso)4E protein variant as defined above, a vector comprising said nucleic acid and a genetically modified or edited maize plant or seed resistant to at least one maize virus, comprising at least one eIF(iso)4E protein variant as defined above. The present invention also relates to a method for obtaining a genetically modified or edited maize plant resistant to at least one maize virus.

  • TARGETED GENE INTEGRATION IN PLANTS
    Publication number: 20250263733
    Abstract: The present invention relates to a vector suitable for a targeted integration of at least one gene of interest in 5? or 3? of a polyubiquitin gene in a plant. The present invention also relates to the use of said vector in a method for targeted insertion of at least one gene of interest in a plant genome and to a plant cell or plant tissue obtained by transformation with said vector. The present invention further relates to a method of identifying a plant having at least one gene of interest inserted in 5? or 3? of a polyubiquitin gene.
