The invention relates to the technical field of plant genetic engineering, and discloses a limonium bicolor gene LbYAB1 and application thereof. The new function of the LbYAB1 is found, firstly, the expression of the LbYAB1 in salt glands and leaf primordia is proved through RNA in-situ hybridization and a promoter driven GUS tissue staining technology, and the expression of the LbYAB1 is induced by treatment of 6-benzylaminopurine. Secondly, a genetic transformation technology is updated, a stable overexpressed LbYAB1 strain is obtained, and by exploring the LbYAB1 function of an overexpressed and silent strain, it is found that compared with a wild type, development of salt glands of the overexpressed strain is inhibited, the salt secreting capacity is weakened, and the salt tolerance is reduced; a silent strain shows an opposite phenotype, and a result proves that the LbYAB1 is a negative regulation factor for salt gland development. Overexpression of the gene in limonium bicolor and arabidopsis thaliana both leads to enhancement of salt sensitivity.
