The present disclosure provides plant transformation vectors, T-DNA insert regions, and transformed plants. The vectors are designed to be a binary vector for use in plant transformations for such as potato. The transformed plants are characterized in that they contain the T-DNA insert region comprising stacked expression cassettes and the corresponding phenotype. The present disclosure also provides methods for identifying genetic material in transformed plants, including in food products made from such plants. The disclosure further relates to the materials and/or means for detecting plant transformation events and methods for detecting presence of plant transformation events.
