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.
Claims20
A mutant allele of the ACO2 gene comprising a mutation in the DIOX_N domain of the wild type ACO2 gene nucleotide sequence of SEQ ID NO:
- 1, wherein the mutation if homozygously present in the genome of a cucumber plant, 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 on position 278 of the wild type ACO2 gene nucleotide sequence of SEQ ID NO:
- 1.
A method for selecting a cucumber plant that produces only male flowers from a population of plants, comprising detecting a deletion of the nucleotide on position 278 of SEQ ID NO:
- 1 in the genome of a plant in a population of plants, and selecting the plant comprising the deletion homozygously.
