The invention relates to the technical field of plant genetic engineering, and particularly discloses an application of a corn CIPK42 protein and a coding gene of the corn CIPK42 protein in regulationand control of salt stress tolerance of plants. The corn ZmCIPK42 gene is found to be able to positively regulate and control the salt tolerance of the plants; and the salt tolerance of the plants can be effectively improved by increasing of the expression quantity of the ZmCIPK42 gene. According to the invention, transgenic corn and arabidopsis thaliana plants with ZmCIPK42 overexpression are constructed; and compared with a non-transgenic wild type, the transgenic corn and arabidopsis thaliana plants are significantly improved in salt tolerance and growth. Discovery of the salt-tolerant function of the ZmCIPK42 gene provides a novel gene target and resource for cultivation of salt-tolerant plant varieties, is of great significance to research of a salt-tolerant molecular mechanism of the plants, and lays a cert
