Plant having low-temperature stress resistance and method of producing the same The present invention relates to a method of producing plants with improved low-temperature stress resistance, comprising the step of transforming cells of a plant with an exogenous arginine decarboxylase ADC1 gene sequence under the control of a promoter capable of functioning in the plant. The plants thus obtained show low-temperature stress resistance without being affected the phenotype when compared with the wild type plant's phenotype.
