  • Publication number: 20170314039
    Abstract: The present invention relates to a plant belonging to the Solanaceae family wherein said plant comprises a genetic trait providing Phytophthora resistance and wherein said resistance trait is encoded by a combination of at least two genes having a reduced expression, or transcription, of said genes or a reduced activity of proteins encoded by said genes as compared to said plant belonging to Solanaceae family being susceptible to Phytophthora. The present invention especially relates to plants belonging to the Solanaceae family selected from the group consisting of sweet pepper (Capsicum annuum), Capsicum spp., potato (Solanum tuberosum), petunia, tomato (Solanum lycopersicum), Nicotinia benthamiana, and tabacco (Nicotinia tabacum), and the present Phytophthora resistance is especially a resistance to a plant pathogen selected from the group consisting of Phytophthora spp., Phytophthora capsici, Phytophthora infestans, and Phytophthora nicotinae.
