発明の名称 (英語) Composition for production of plant body having improved sugar content, and use thereof 実績あり
発明の概要(英語) The composition, in accordance with the present invention, for producing a plant body having an improved sugar content includes glutathione, a polynucleotide encoding γ-glutamylcysteine synthetase, or a polynucleotide encoding glutathione-binding plastid type fructose-1,6-bisphosphate aldolase.
The composition preferably includes oxidized glutathione.
This allows provision of a composition for easily producing a plant body having an improved sugar content.
従来技術、競合技術の概要(英語) BACKGROUND ART
A plant such as fruit, vegetable, and cereal generally includes sugar.
An amount of sugar in the plant is represented by a sugar content.
The sugar content affects a commercial value of plant depending on a type of the plant.
Therefore, in recent years, technical developments for increasing a sugar content of a plant have been carried out.
For example, tomatoes of high sugar content are produced mainly by soil culture.
Further, a technique for producing tomatoes of high sugar content by nutrient solution culture has been suggested (Patent Literature 1).
It is known that a substance for regulating an oxidation-reduction state of a cell, such as glutathione, can function as a differentiation control agent for a cell or an organ (Patent Literature 2).
Further, it is known that glutathione can function as a plant growth control auxiliary agent (Patent Literature 3).

特許請求の範囲(英語) [claim1]
1. A method for producing a plant with increased sugar content relative to a corresponding untreated plant, the method comprising the steps of: applying glutathione to a plant or soil in which a plant is to be cultivated;
cultivating the plant under conditions suitable for growth; and
selecting for a plant having increased sugar content relative to a corresponding untreated plant.
[claim2]
2. The method according to claim 1, wherein the glutathione is oxidized glutathione.
[claim3]
3. The method according to claim 1, wherein the step of applying the effective amount of glutathione comprises applying 0.01 mM to 20 mM to the plant or soil.
[claim4]
4. The method according to claim 1, wherein the step of applying the effective amount of glutathione comprises applying 0.1 mM to 2 mM to the plant or soil.
[claim5]
5. The method according to claim 1, wherein the step of applying the effective amount of glutathione to the plant comprises applying glutathione to an entire plant, or to one or more portions of the plant.
[claim6]
6. The method according to claim 1, wherein the plant is grown from one or more seeds, and the step of applying the effective amount of glutathione comprises applying in regular intervals for at least 30 days beginning on the day of sowing the seeds.
[claim7]
7. The method according to claim 6, wherein the step of applying the effective amount of glutathione comprises applying in regular intervals for at least 60 days beginning on the day of sowing.
[claim8]
8. The method according to claim 6, further comprising harvesting the plant, and wherein the step of applying the effective amount of glutathione comprises applying glutathione one to four times per week from the day of sowing until harvesting.
[claim9]
9. The method according to claim 8, wherein glutathione is applied one to four times per week in an amount of 0.001-0.1 mmol per application.
[claim10]
10. The method of claim 1, wherein the step of applying the effective amount of glutathione comprises applying glutathione in regular intervals selected from the group consisting of: until bud break, after flower petals have fallen, from bud break until production of fruit, from flowering time until production of fruit, or from a time after petals have fallen until production of fruit.
[claim11]
11. The method of claim 1, further comprising harvesting the plant, and wherein the step of applying the effective amount of glutathione comprises applying glutathione in regular intervals 10 days before harvesting until harvesting.
[claim12]
12. The method of claim 1, further comprising harvesting the plant, and wherein the step of applying the effective amount of glutathione comprises applying glutathione in regular intervals 20 days before harvesting until harvesting.
