PARTHENOCARPY REGULATION GENE AND USE THEREOF

摘要

In order to identify a novel gene responsible for parthenocarpy and to provide use of the gene, the parthenocarpy regulatory gene of the present invention includes a polynucleotide (1) that encodes an amino acid sequence represented by SEQ ID NO: 1, (2) that encodes an amino acid sequence (i) having a sequence identity of 75% or higher relative to the amino acid sequence represented by SEQ ID NO: 1, (3) that encodes an amino acid sequence in which 1 to 98 amino acids are substituted, etc. in the amino acid sequence represented by SEQ ID NO: 1, or (4) that is hybridized with a polynucleotide, which has a sequence complementary to the polynucleotide for encoding the amino acid sequence represented by SEQ ID NO: 1 under a stringent condition.

主权项

1. A method for evaluating parthenocarpy of a plant, said method comprising the step of:
checking whether or not expression of a parthenocarpy regulatory gene, which includes a polynucleotide recited in any of (1) through (4) below, is inhibited in the plant; or checking whether or not a function of a polypeptide, which is encoded by the parthenocarpy regulatory gene, is inhibited in the plant. (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 75% or higher relative to the amino acid sequence represented by SEQ ID NO: 1 and (ii) having a parthenocarpy regulatory activity, (3) a polynucleotide that encodes a polypeptide (i) having an amino acid sequence in which 1 to 98 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 regulatory 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 regulatory activity.
