Summary:The invention discloses a plant root-promoting gene LTP2 as well as a promoter, an expression product, an expression vector and application thereof, and aims to solve the technical problem that the effect of improving plant root development by using cultivation measures is effective and unstable from the aspect of molecular biology. According to the application, a gene LTP2 capable of regulating and controlling root development is identified, an overexpression vector of the LTP2 gene is constructed, and overexpression strains are obtained through respective transformation; phenotype identification and detection show that LTP2 can regulate and control plant root development; a root system specific expression LTP2 promoter is also identified; an eukaryotic expression vector for plant genetic transformation is designed and can drive specific expression of a target gene in a root system. The functional research on the LTP2 gene and the promoter thereof is beneficial to regulation and control of plant root system
