The present application provides: a fruit-bearing plant exhibiting parthenocarpy or a portion thereof including a mutation in a Solyc10g038170 gene or ortholog thereof, the mutation causing deficiency or reduction in expression of a protein encoded by the Solyc10g038170 gene or ortholog thereof; a method for producing a parthenocarpic fruit-bearing plant or a portion thereof; and a method for selecting a parthenocarpic fruit-bearing plant or a portion thereof.

Fruit-bearing plant exhibiting high temperature resistance, high yield, and parthenocarpy

An expression system is provided, including a first nucleic acid fragment containing a long intergenic region (LIR) derived from geminivirus, a small intergenic region (SIR) derived from geminivirus, and an expression cassette of a target protein linked between the LIR and the SIR and a second nucleic acid fragment containing an expression cassette of a Rep/RepA protein derived from geminivirus, in which the expression cassette of the target protein includes a promoter, a nucleic acid fragment encoding the target protein, and two or more linked terminators in this order.

Protein expression system in plant cell and use thereof

It is an object of the present invention to provide a method for introducing a protein into a plant, which is simple and extensively applicable to various types of plant cells and proteins. The above object is achieved by the present invention to provide a complex comprising a protein of interest to be introduced into a target plant cell and a carrier peptide, a method for introducing a protein of interest into a target plant cell using the complex, and a kit comprising a protein of interest to be introduced into a target plant cell and a carrier peptide.

Method for introducing protein into plant cell

The present invention relates to a plant having an improved sugar content in fruit compared with its wild type plant, which has a mutant cyclin F-box gene comprising a nucleotide mutation that causes a non-conservative amino acid substitution in the cyclin F-box protein. The present invention also relates to a parthenocarpic plant having a mutant cyclin F-box gene comprising a nucleotide mutation that causes a non-conservative amino acid substitution in the cyclin F-box protein.

Plant having mutant cyclin F-box gene

Provided is a plant such as tomato, in which plant vigor has been increased and heat resistance has further been imparted. A plant such as tomato can be obtained, which has increased the stem diameter as well as the plant height and has become heat resistant by having a mutant Della protein, in which a leucine corresponding to the leucine at position 567 in SEQ ID NO: 2 in the amino acid sequence of the Della protein has been replaced by another amino acid, preferably phenylalanine.

Mutant plant

A heat-tolerant tomato plant exhibiting a high capacity for developing seed-containing fruits under high temperature conditions is provided. The present invention relates to a method for producing a heat-tolerant tomato plant comprising introducing a genetic mutation into a tomato plant, wherein the mutation improves the pollen viability and the capacity for developing seed-containing fruits under high temperature conditions compared with wild-type plant; and a heat-tolerant tomato plant into which the mutation has been introduced.

Heat-tolerant tomato mutant and method for producing the same

The present invention relates to anhaving improved gene transfer efficiency. The present invention provides a transformedwhich harbors a foreign GABA transaminase gene and exhibits improved gene transfer efficiency, and a method for producing a transformed plant using the same.
