Modified CULLIN1 gene

A method for selecting a Cucumis sativus plant, a Cucumis melo plant, a Cucurbita pepo plant, or a Citrullus lanatus plant comprising a modified Cullin1 gene and expressing a modified Cullin1 protein comprising a single non-silent amino acid substitution, wherein the Cucumis sativus plant, a Cucumis melo plant, a Cucurbita pepo plant, or a Citrullus lanatus plant expressing the modified Cullin1 protein exhibits a compact growth phenotype as compared to an isogenic line not comprising the modified Cullin 1 protein wherein the method comprises;

• a) testing the plant for presence of the modified Cullin1 gene, or for the presence of the modified Cullin 1 protein,
• wherein:
• when the plant is a Cucumis sativus plant, the testing comprises detecting modification of the nucleotide sequence of SEQ ID NO:
• 1 leading to change of the amino acid sequence of SEQ ID NO:
• 18, or detecting modification of the amino acid sequence of SEQ ID NO:
• 18 in the region that binds SKP1 and/or ETA2, wherein the modification of the nucleotide sequence of SEQ ID NO:
• 1 confers a substitution in the Cullin1polypeptide sequence of SEQ ID NO:
• 18 between positions 30 to 60 of SEQ ID NO:
• 18, wherein the modification of the nucleotide sequence excludes the substitution of A to G at position 147 of SEQ ID NO:
• 1;
• when the plant is a Cucumis melo plant, the testing comprises detecting modification of the nucleotide sequence of SEQ ID NO:
• 2 leading to change of the amino acid sequence of SEQ ID NO:
• 19, or detecting modification of the amino acid sequence of SEQ ID NO:
• 19 in the region that binds SKP1 and/or ETA2 wherein the modification of the nucleotide sequence of SEQ ID NO:
• 2 confers a substitution in the Cullin1polypeptide sequence of SEQ ID NO:
• 19 between positions 30 to 60 of SEQ ID NO:
• 19;
• when the plant is a Cucurbita pepo plant, the testing comprises detecting modification of the nucleotide sequence of SEQ ID NO:
• 3 leading to change of the amino acid sequence of SEQ ID NO:
• 20, or detecting modification of the amino acid sequence of SEQ ID NO:
• 20 in the region that binds SKP1 and/or ETA2 wherein the modification of the nucleotide sequence of SEQ ID NO:
• 3 confers a substitution in the Cullin 1polypeptide sequence of SEQ ID NO:
• 20 between positions 30 to 60 of SEQ ID NO:
• 20;
• when the plant is a Citrullus lanatus plant, the testing comprises detecting modification of the nucleotide sequence of SEQ ID NO:
• 4 leading to change of the amino acid sequence of SEQ ID NO:
• 21, or detecting modification of the amino acid sequence of SEQ ID NO:
• 21 in the region that binds SKP1 and/or ETA2 wherein the modification of the nucleotide sequence of SEQ ID NO:
• 4 confers a substitution in the Cullin 1polypeptide sequence of SEQ ID NO:
• 21 between positions 30 to 60 of SEQ ID NO:
• 21;
• b) selecting the Cucumis sativus plant, Cucumis melo plant, Cucurbita pepo plant, or Citrullus lanatus plant having the modified Cullin1 gene or the modified Cullin 1 protein;
• and
• c.) growing the Cucumis sativus plant, Cucumis melo plant, Cucurbita pepo plant,
• or Citrullus lanatus plant exhibiting a compact growth phenotype compared to an isogenic line not comprising the modified Cullin1 gene.
