Expression enhancing method of genes involved in saponin biosynthesis by light irradiation

摘要

[Task] improve the saponin generation capacity of the plant. According to the present invention relates, to a plant, by irradiating a light containing a wavelength component in the wavelength region of 435nm~480nm, it is possible to enhance the expression of squalene epoxidase gene of the plant. Thus, squalene epoxidase can be made to accelerate the conversion reaction from squalene to 2,3-oxidosqualene with, thereby enabling efficient production of saponins such as 2,3-oxidosqualene metabolites. .BACKGROUND
