Disease resistance-related protein rcr1, coding gene thereof, and use thereof

A method for cultivating a transgenic plant or a gene-edited plant with an enhanced disease resistance, comprising the following steps:

• increasing a content and/or an activity of a RCR1 protein in a recipient plant to obtain the transgenic plant or the gene-edited plant, wherein a disease resistance of the transgenic plant or the gene-edited plant is higher than a disease resistance of the recipient plant;
• wherein the RCR1 protein is as defined in N1) or N2) or N3) or N4):
• N1) a protein having the amino acid sequence of SEQ ID NO:
• 2;
• N2) a fusion protein obtained by attaching a tag to an N-terminus and/or a C-terminus of the protein of SEQ ID NO:
• 2;
• N3) a plant disease resistance-related protein derived from the amino acid sequence of SEQ ID NO:
• 2 by a substitution, and/or a deletion, and/or an addition of one or more amino acid residues;
• or
• N4) a plant disease resistance-related protein having 75% sequence identity to SEQ ID NO:
• 2.

A method for cultivating a transgenic plant or a gene-edited plant with a reduced disease resistance, comprising steps of:

• reducing an activity and/or a content of a RCR1 protein in a recipient plant to obtain the transgenic plant or the gene-edited plant, wherein the transgenic plant or the gene-edited plant has a disease resistance lower than a disease resistance of the recipient plant;
• the RCR1 protein is as defined in N1) or N2) or N3) or N4):
• N1) a protein having the amino acid sequence of SEQ ID NO:
• 2;
• N2) a fusion protein obtained by attaching a tag to an N-terminus and/or a C-terminus of the protein of SEQ ID NO:
• 2;
• N3) a plant disease resistance-related protein derived from the amino acid sequence of SEQ ID NO:
• 2 by a substitution, and/or a deletion, and/or an addition of one or more amino acid residues;
• or
• N4) a plant disease resistance-related protein having 75% sequence identity to SEQ ID NO:
• 2 and retaining a plant disease resistance-related activity.
