Parthenocarpy regulation gene and use thereof

A method for producing a parthenocarpy-regulated plant, said method comprising the step of:

• inhibiting, in a plant, gene expression of a parthenocarpy regulatory gene that includes a polynucleotide recited in any of (1) through (4) below;
• or
• inhibiting, in a plant, a function of a polypeptide encoded by the parthenocarpy regulatory gene.
• (1) A polynucleotide that encodes a polypeptide having an amino acid sequence represented by SEQ ID NO:
• 1,
• (2) a polynucleotide that encodes a polypeptide (i) having a sequence identity of 70% or higher relative to the amino acid sequence represented by SEQ ID NO:
• 1 and (ii) having a parthenocarpy regulation activity,
• (3) a polynucleotide that encodes a polypeptide (i) having an amino acid sequence in which 1 to 87 amino acids are substituted in, deleted from, inserted into, and/or added to the amino acid sequence represented by SEQ ID NO:
• 1 and (ii) having a parthenocarpy regulation activity, and
• (4) a polynucleotide that (i) is hybridized with a polynucleotide, which has a sequence complementary to the polynucleotide recited in the above (1), under a stringent condition and (ii) encodes a polypeptide having a parthenocarpy regulation activity.

A parthenocarpy regulatory gene that includes a polynucleotide recited in any of (1) through (4) below.

• (1) A polynucleotide that encodes a polypeptide having an amino acid sequence represented by SEQ ID NO:
• 1,

• 1 and (ii) having a parthenocarpy regulation activity,
• (3) a polynucleotide that encodes a polypeptide (i) having an amino acid sequence in which 1 to 87 amino acids are substituted in, deleted from, inserted into, and/or added to the amino acid sequence represented by SEQ ID NO:
• 1 and (ii) having a parthenocarpy regulation activity, and
• (4) a polynucleotide that (i) is hybridized with a polynucleotide, which has a sequence complementary to the polynucleotide recited in the above (1), under a stringent condition and (ii) encodes a polypeptide having a parthenocarpy regulation activity.

A polypeptide recited in any of (1) through (4) below.

• (1) A polypeptide having an amino acid sequence represented by SEQ ID NO:
• 1,
• (2) a polypeptide (i) having a sequence identity of 70% or higher relative to the amino acid sequence represented by SEQ ID NO:
• 1 and (ii) having a parthenocarpy regulation activity,
• (3) a polypeptide (i) having an amino acid sequence in which 1 to 87 amino acids are substituted in, deleted from, inserted into, and/or added to the amino acid sequence represented by SEQ ID NO:
• 1 and (ii) having a parthenocarpy regulation activity, and
• (4) a polypeptide that (i) is encoded by a polynucleotide which is hybridized, under a stringent condition, with a polynucleotide that has a sequence complementary to a polynucleotide for encoding the polypeptide recited in the above (1) and (ii) has a parthenocarpy regulation activity.
