  • Transgenic plants and method for transforming carnations
    Patent number: 7129393
    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.
