Abstract
The present invention relates to a mutant ACO2 gene allele, which leads to a plant of the family of Cucurbitacea, in particular a cucumber plant producing only male flowers. The invention also relates to a plant of the family of Cucurbitacea, in particular a cucumber plant, comprising the mutant ACO2 gene allele. The mutant ACO2 allele provides plants that only produce male flowers. The invention further relates to the use of the mutant allele of the ACO2 gene for the identification and development of a plant of the family of Cucurbitacea, in particular a cucumber plant, producing only male flowers.
Claims13
An agronomically elite, or a hybrid variety or inbred cucumber plant having a mutant allele of the 1-aminocyclopropane-1-carboxylate oxidase 2 (ACO2) gene,
- wherein the mutant allele comprises a deletion of the nucleotide at position 278 in the wild type nucleotide sequence of SEQ ID NO:
- 1, or having a mutant allele of the 1-aminocyclopropane-1-carboxylate oxidase 2 (ACO2) gene comprising SEQ ID NO:
- 3,
- wherein the deletion of the nucleotide position at 278 in the wild type nucleotide sequence SEQ ID NO:
- 1 leads to a premature stop codon, and
- wherein the mutant allele, if homozygously present in the genome of a cucumber plant, results in a cucumber plant producing only male flowers.
An agronomically elite, or a hybrid variety or inbred cucumber plant having a mutant allele of the 1-aminocyclopropane-1-carboxylate oxidase 2 (ACO2) gene,
- wherein the mutant allele comprises a deletion of the nucleotide at position 278 in the wild type nucleotide sequence of SEQ ID NO:
- 1, or having a mutant allele of the 1-aminocyclopropane-1-carboxylate oxidase 2 (ACO2) gene comprising SEQ ID NO:
- 3,
- wherein the deletion of the nucleotide position at 278 in the wild type nucleotide sequence SEQ ID NO:
- 1 leads to a premature stop codon, and
- wherein the mutant allele is homozygously present in the genome of a cucumber plant and results in a cucumber plant producing only male flowers, and
- wherein representative seed of a cucumber plant having the mutant allele of the ACO2 gene was deposited under NCIMB Accession No. 42987.
A cucumber seed comprising a mutant allele of the ACO2 gene,
- wherein the mutant allele comprises a deletion of the nucleotide at position 278 in the wild type nucleotide sequence of SEQ ID NO:
- 1, or having a mutant allele of the 1-aminocyclopropane-1-carboxylate oxidase 2 (ACO2) gene comprising SEQ ID NO:
- 3,
- wherein the deletion of the nucleotide position at 278 in the wild type nucleotide sequence SEQ ID NO:
- 1 leads to a premature stop codon, and
- wherein the mutant allele, if homozygously present in the genome of a cucumber plant grown from said seed, results in a cucumber plant producing only male flowers.
A marker for identifying a cucumber plant comprising a mutant ACO2 allele, wherein the marker comprises a deletion of a nucleotide at position 278 of the wild type ACO2 gene nucleotide sequence of SEQ ID NO:
- 1, and the marker has the sequence of SEQ ID NO:
- 6.
A method for selecting a cucumber plant that produces only male flowers from a population of cucumber plants, comprising detecting a deletion of the nucleotide at position 278 of SEQ ID NO:
- 1 in the genome of the cucumber plant in a population of cucumber plants, and selecting the cucumber plant comprising the deletion homozygously.
