|1. (WO2018164281) METHOD FOR MODIFYING FRUITS, ETC. AND CULTURED CELLS THEREOF|
|Title:||METHOD FOR MODIFYING FRUITS, ETC. AND CULTURED CELLS THEREOF|
Provided is a method whereby fruits, etc. are modified by electrically stimulating an orchard tree such as grape or a vegetable to thereby achieve modification effects of, for example, improving the disease resistance, enhancing the repellent effect, increasing the sugar content, decreasing the acidity, and increasing the enzyme content of the fruits, etc. An electrode and a counter electrode are inserted into different sites of an orchard tree or an annual herbal plant. Then, a voltage is impressed between the electrodes while keeping the both electrodes in contact with internal tissues. Thus, fruits, etc. are modified and, for example, the disease resistance thereof is improved. Examples of the orchard tree include not only fruit-bearing perennial arboreous plants but also rootstock plants for orchard trees such as banana, pineapple, papaya and passion fruit. According to this method, the expression amount of a gene capable of producing a disease-resistant protein can be increased within the plant, or the sugar content of fruits can be increased and the acidity thereof can be decreased. In the case where the orchard tree is a grape tree, in particular, the anthocyanin content and resveratrol content of grape fruits can be increased.
