    摘要: The invention relates to a Brassica plant that is resistant to Hyaloperonospora brassicae, which plant may comprise a QTL on chromosome 8, and optionally a QTL on chromosome 4, and/or a QTL on chromosome 1. The presence of the QTL on chromosome 8 can be identified by use of at least one of the markers selected from the group consisting of SEQ ID NOS: 1 to 7; the presence of the QTL on chromosome 4 can be identified by use of at least one of the markers selected from the group consisting of SEQ ID NOS: 8 to 16; and the presence of the QTL on chromosome 1 can be identified by use of at least one of the markers selected from the group consisting of SEQ ID NOS: 17 to 22. The QTL is as comprised in the genome of a Brassica plant representative seed of which was deposited with the NCIMB under accession number NCIMB 43346.

    摘要: The present invention relates to the field of plant biotechnology. Specifically, there are provided methods and nucleic acid sequences for obtaining pathogen resistance in plants and for generating resistant plants. In particular, the role of a central molecule in plant immunity is studied. Based on the mechanisms elucidated, the present invention provides strategies to specifically modulate said phosphatase-like protein family member molecule by different transient and/or stable techniques, alone or in combination, to achieve a robust increased of pathogen resistance in different target plants to obtain inherently pathogen resistant plants and plant materials to avoid severe harvest losses as caused by major plant pathogens by biological means instead of herbicide or pesticide treatment.

    摘要: The use of a negative regulator AtRTP5 for increasing the plant resistance to Phytophthora is disclosed. The AtRTP5 gene negatively regulates the plant resistance to Phytophthora by interfering with a plant hormone immune signaling pathway. The AtRTP5 gene has a nucleotide sequence shown as SEQ ID NO: 1 or a homologous sequence having more than 50% homology with the sequence. The use of a protein encoded by a negative regulator AtRTP5 for increasing the plant resistance to Phytophthora is also disclosed. The plant resistance to Phytophthora is enhanced by reducing the expression of the protein encoded by the AtRTP5 gene with genetic engineering. The protein has an amino acid sequence shown as SEQ ID NO: 2 or a homologous sequence having more than 50% homology with the sequence.
