Method for delaying senescence of plants using the gene regulating leaf longevity in plants

摘要

PURPOSE: A method for delaying senescence of plants using a gene regulating leaf longevity in plants is provided, thereby improving tolerance of plants to oxidative stress or high density salt and delaying senescence of plants by transforming plants with the ORE8 gene. CONSTITUTION: A method for delaying senescence of plants comprises transforming plants with a gene encoding a protein having the amino acid sequence set forth in SEQ ID NO: 2, wherein the gene is ORE8 gene having the nucleotide sequence set forth in SEQ ID NO: 1; the ORE8 gene is isolated from Arabidopsis thaliana and improves tolerance of plants to salt or oxidative stresses; and the plant is selected from food crops including rice, wheat, barley, corn, bean, potato, red bean, oat and Indian millet, vegetables including Arabidopsis, Chinese cabbage, radish, red pepper, strawberry, tomato, watermelon, cucumber, cabbage, melon, pumpkin, Welsh onion, onion and carrot, special use crops including ginseng, tobacco, cotton, sesame, sugar cane, sugar beet, Perilla japonica, peanut and rape, fruit trees including apple tree, pear tree, jujube tree, peach, kiwi, grape, tangerine, persimmon, plum, apricot and banana, flowers including rose, gladiolus, gerbera, carnation, chrysanthemum, lily and tulip, and fodder crops including rye grass, red clover, orchard grass, tall fescue and perennial ryegrass.
