Method for producing transgenic cucumber that produces high levels of superoxide dismutase

摘要

The present invention relates to transgenic plants that produces high levels of superoxide dismutase (SOD) and to methods for producing said transgenic plants. More particularly, the present invention relates to a transgenic plant and a method, in which the hypocotyl section of seedlings is co-cultured with Agrobacterium transformant and regenerated by adventitious shoot induction and by root induction, where saidAgrobacterium transformant contains an expression vector which comprises the promoter of fruit-dominant ascorbate oxidase gene, SOD gene isolated from cassava, and herbicide-resistant bar gene. The present invention also relates to a method for inducing adventitious shoots from the hypocotyl section in plant tissue culture, thus providing a method for the efficient production of transgenic plants maintaining higher SOD activity in fruits. Therefore, the SOD transgenic cucumber in the present invention can be used as a material for cosmetics, additives in functional foods, and medicines as well as a substance which has tolerance to herbicides and environmental stresses.
