The present invention relates to a use of AtBG1 {Arabidopsis thaliana β-glucosidase 1) gene and a transgenic plan with the AtBG1 gene insertion, more precisely, a use of AtBG1 gene for the generation of a transgenic plant having resistance to various environmental stresses by increasing the level of abscisic acid (ABA), a kind of plant hormone, and a transgenic plant having stress-resistance with the AtBG1 gene insertion. Plants have enhanced resistance against various environmental stresses including low temperature, salt damage and dehydration owing to the increased level of ABA. Thus, the method to increase the level of ABA can greatly contribute to the enhancement of agricultural production.
