Abstract: A method of generating genotypic variation in a genome of a plant is disclosed. The method comprising introducing into the plant at least one viral expression vector encoding at least one chimeric nuclease which comprises a DNA binding domain, a nuclease and a localization signal to a DNA-containing organelle, wherein the DNA binding domain mediates specific targeting of the nuclease to the genome of the plant, thereby generating genotypic variation in the genome of the plant.

Abstract: A method of generating genotypic variation in a genome of a plant is disclosed. The method comprising introducing into a gamete or a gamete producing tissue of the plant at least one viral expression vector encoding at least one chimeric nuclease which comprises a DNA binding domain, a nuclease and a localization signal to a DNA-containing organelle, wherein the DNA binding domain mediates specific targeting of the nuclease to the genome of the plant, wherein the introducing is performed such that the gamete or gamete producing tissue expresses the chimeric nuclease but not all plant tissues express the chimeric nuclease, thereby generating genotypic variation in the genome of the plant.

Abstract: A method of transforming a carnation (Dianthus L.) plant genome with a DNA molecule. The method comprises (a) preparing stem explants from carnation cuttings; (b) wounding the explants by microprojectile bombardment; (c) cocultivating the wounded explants with Agrobacterium comprising the DNA molecule under defined conditions of exposure to dark followed by light; (d) excising shoots from the cultivated wounded explants and removing the leaves from the shoots; and (e) culturing the leaves to obtain transgenic shoots transformed with the DNA molecule. Also disclosed are a rolC-transgenic carnation with improved agronomic traits and enhancement of flower fragrance by antisense suppression of the flavonoid gene fht.

Abstract: A method for transforming a gypsophila plant with a nucleic acid of interest comprising: (i) pre-treating said gypsophila plant with a gibberellin, (ii) obtaining a plant segment from said treated plant; (iii) co-cultivating said plant segment with an Agrobacterium vector comprising said nucleic acid of interest; and (iv) selecting a transformed plant segment and regenerating a transformed plant therefrom.
