[Abstract] In order to study the salt-tolerant activity of Ginseng Redoxin gene and provide reference for its application in stress-resistant breeding of Ginseng, positive Arabidopsis thaliana plants were obtained by plant transformation technology and NaCl application at different concentrations, and seed germination rate, plant survival rate and plant growth were used to investigate different salt concentrations and different plant types. The main root length, branch number and other related indicators. The results show that the seed germination rate of transgenic Arabidopsis is higher than that of wild Arabidopsis under salt stress; the survival rate of transgenic Arabidopsis is significantly higher than that of wild Arabidopsis under salt stress; the main roots of transgenic Arabidopsis grew larger than that of wild Arabidopsis under salt stress; and the transgenic Arabidopsis under salt stress. There is no significant difference in the number of branches between Arabidopsis thaliana and wild type Arabidopsis thaliana. It is concluded that the ginsenoside gene improves the ability of transgenic Arabidopsis thaliana to resist high salt stress.
