Root-knot nematode resistance conferring gene

A method for producing a Solanum lycopersicum plant comprising a MeR1 gene and an allele of the NRC6 gene comprising:

• (I) crossing a first Solanaceae parent plant with a second Solanum lycopersicum plant to obtain an F1 population;
• (II) optionally performing one or more rounds of selfing and/or crossing with a F1 Solanum lycopersicum plant to obtain a further generation population;
• (III) selecting from the population resulting from the cross of step al), or from the further generation population of step II), a Solanum lycopersicum plant that comprises the MeR1 gene and the allele of the NRC6 gene;
• wherein said MeR1 gene:
• encodes an MeR1 protein;
• and
• a) comprises a nucleotide sequence comprising a coding sequence according to SEQ ID NO:
• 2, 3, 4, 5, 6, 7, 8 or 9;
• or
• b) comprises a nucleotide sequence encoding the MeR1 protein, wherein the
• MeR1 protein has an amino acid sequence according to SEQ ID NO:
• 10, 11, 12, 13, 14, 15, 16 or 17;
• and
• wherein said NRC6 gene:
• encodes a NRC6 protein;
• and
• c) comprises a nucleotide sequence comprising a coding sequence according to SEQ ID NO:
• 19, 22, 24, 26, or 28;
• or
• d) comprises a nucleotide sequence encoding the NRC6 protein, wherein the NRC6 protein has an amino acid sequence according to SEQ ID NO:
• 20, 23, 25, 27, or 29;
• (IV) additionally testing the selected plant for resistance to Meloidogyne enterolobii;
• and
• (V) selecting the additionally tested plant that exhibits resistance to Meloidogyne enterolobii.
