The invention belongs to the field of plant molecular biology, and relates to application and a method of a vietnamese sophora root DNA methylase gene in improving cadmium stress tolerance of plants. The invention provides a DNA methylase gene StCMT1 from vietnamese sophora root, the nucleotide sequence of the DNA methylase gene StCMT1 is shown as SEQ ID No.2, and the amino acid sequence of an encoded protein is shown as SEQ ID No.1. According to the invention, by combining transcriptome screening with qRT-PCR verification, StCMT1 is determined as a key candidate gene for continuous inducible expression under cadmium stress; functional verification is carried out in tobacco, it is proved that overexpression of StCMT1 can enhance cadmium resistance under the stress conditions of 100 [mu] M and 200 [mu] M CdCl2, and definite repeatability and application value are achieved. The method can be used for constructing cadmium-resistant plant materials and cultivating cadmium-resistant varieties, and a new molecular target and technical scheme are provided for safe production of cadmium-contaminated soil and quality improvement of medicinal plants.
