  • Publication number: 20200392530
    Abstract: A dicot plant cell, plant tissue or plant having a reduced expression of a wild type protein having at least 75% sequence identity with SEQ ID NO. 1 is disclosed. Also disclosed is a plant cell, plant tissue or plant comprising a modified protein and/or a truncated protein having at least about 75% sequence identity when calculated over the positions corresponding to positions 1-66 and positions 78-308 of SEQ ID NO: 1. The modified protein increases the resistance to Geminiviridae. Nucleic acid constructs encoding the modified or truncated protein are also provided. Lastly, methods for generating a plant cell, plant tissue or plant comprising the modified protein that increases the resistance to Geminiviridae are disclosed.

  • Patent number: 10273500
    Abstract: The present invention relates to powdery mildew resistance providing genes of the Cucumis family, and especially Cucumis sativus, wherein said resistance is provided by impairment of the present genes. Further, the present invention relates plants comprising the present impaired resistance conferring genes and seeds, embryos or other propagation material thereof. Especially, the present invention relates to powdery mildew resistance conferring genes, wherein the amino acid sequence encoded by said resistance conferring gene is selected from the group consisting of SEQ ID NO: 2, SEQ ID NO: 4, SEQ ID NO: 6, SEQ ID NO: 8, SEQ ID NO: 10, SEQ ID NO: 12, SEQ ID NO: 14, SEQ ID NO: 16, SEQ ID NO: 18, SEQ ID NO: 20, and SEQ ID NO: 22, and amino acid sequences with more than 70% identity, preferably more than 80% identity, more preferably more than 90% identity, and most preferably more than 95% identity.

  • Publication number: 20040093635
    Abstract: Genomic sequences encoding Phytophthora infestans resistance proteins are provided herein. Specifically, sequences from potato required for P. infestans resistance have been cloned and sequence provided, together with the encoded amino acid sequence. DNA encoding the amino acid sequence or amino acid sequences showing a significant degree of homology thereto may be introduced into plant cells and the encoded polypeptide expressed, conferring P. infestans resistance on plants comprising such cells and descendants thereof.
