abstract |
The invention relates to the field of plant transformation, in particular plant transformation of a Solanaceae, preferably of potato. The present invention provides an alternative selection method in plant transformation processes. The invention further provides a plant that has been provided with additional nucleic acid sequences but which genetically modified plant essentially consists of cis plant sequences, for example a genetically modified potato plant that has been provided with additional (essentially) potato plant sequences. Such a transgenic plant is free from non- Solanum T-DNA border sequences. A preferred embodiment is a potato plant that carries a functional R-gene, providing resistance against an oomycete pathogen, preferably Phytophthora infestans , wherein said R-gene can be used as selectable marker. |
