Seedless fruit producing plants

A method for production of a plant comprising:

• a) identifying a plant which has a mutation in an allele encoding a cyclin SDS like protein encoding gene wherein the wild type allele of the gene encodes a cyclin SDS like protein comprising at least 60% sequence identity to any one of the following proteins:
• SEQ ID NO:
• 2 or SEQ ID NO:
• 6 or SEQ ID NO:
• 12 or SEQ ID NO:
• 19 or SEQ ID NO:
• 20, and optionally
• b) determining whether the plant is male fertile and whether the plant, or a progeny plant produced by self-fertilization, produces seedless fruits and optionally
• c) selecting a plant comprising at least on copy of the mutant allele of a).

A method for production of a plant comprising:

• a) introducing mutations in a population of plants,
• b) selecting a male fertile plant producing seedless fruit,
• c) verifying if the plant selected under b) has a mutation in an allele encoding a cyclin SDS like protein encoding gene and selecting a plant comprising such a mutation, and optionally
• d) growing/cultivating the plants obtained under c), wherein the wild type allele of the gene encodes a cyclin SDS like protein comprising at least 60% sequence identity to any one of the following proteins:
• SEQ ID NO:
• 2 or SEQ ID NO:
• 6 or SEQ ID NO:
• 12 or SEQ ID NO:
• 19 or SEQ ID NO:
• 20.

A method for production of a plant comprising:

• a) introducing a foreign nucleic acid molecule into a plant, wherein the foreign nucleic acid molecule is
• i) a DNA molecule, which codes at least one antisense RNA, which effects a reduction in the expression of an endogenous gene encoding a cyclin SDS like protein;
• ii) a DNA molecule, which by means of a co-suppression effect leads to the reduction in the expression of an endogenous gene encoding a cyclin SDS like protein;
• iii) a DNA molecule, which codes at least one ribozyme, which splits specific transcripts of an endogenous gene encoding a cyclin SDS like protein;
• iv) a DNA molecule, which simultaneously codes at least one antisense RNA and at least one sense RNA, wherein the said antisense RNA and the said sense RNA form a double-stranded RNA molecule, which effects a reduction in the expression of an endogenous gene encoding a cyclin SDS like protein (RNAi technology);
• v) a nucleic acid molecule introduced by means of in vivo mutagenesis, which leads to a mutation or an insertion of a heterologous sequence in an endogenous gene encoding a cyclin SDS like protein, wherein the mutation or insertion effects a reduction in the expression of a gene encoding a cyclin SDS like protein or results in the synthesis of an inactive cyclin SDS like protein;
• vi) a nucleic acid molecule, which codes an antibody, wherein the antibody results in a reduction in the activity of an endogenous gene encoding a cyclin SDS like protein due to the bonding of the antibody to an endogenous cyclin SDS like protein;
• vii) a DNA molecule, which contains transposons, wherein the integration of these transposons leads to a mutation or an insertion in an endogenous gene encoding a cyclin SDS like protein, which effects a reduction in the expression of an endogenous gene encoding a cyclin SDS like protein, or results in the synthesis of an inactive cyclin SDS like protein;
• viii) a T-DNA molecule, which, due to insertion in an endogenous gene encoding a cyclin SDS like protein, effects a reduction in the expression of an endogenous gene encoding a cyclin SDS like protein, or result in the synthesis of an inactive cyclin SDS like protein;
• or
• ix) a nucleic acid molecule encoding rare-cleaving endonucleases or custom-tailored rare-cleaving endonucleases;
• b) selecting a male fertile plant wherein the plant, or a progeny of the plant produced by self-fertilization, produces seedless fruit, optionally
• c) verifying if the plant selected under b) has a decreased activity of a cyclin SDS like protein compared to wild type plants into whose genome no foreign nucleic acid molecules had been integrated, optionally;
• and
• d) growing/cultivating the plants obtained under c).
