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 herein further referred to as a cis-gene plant.
