摘要： FK506-binding proteins (FKBPs), which belong to the peptidyl-prolyl cis/trans isomerase superfamily, are involved in plant response to abiotic stresses. A number of FKBP family genes have been isolated in plants, but little has been reported of FKBP genes in maize. In this study, a drought-induced FKBP gene, ZmFKBP20-1, was isolated from maize and was characterized for its role in stress responses using gene expression, protein subcellular localization, transformation in Arabidopsis, expression patterns of the stress-responsive genes, and physiological parameter analysis. During drought and salt stresses, ZmFKBP20-1 transgenic Arabidopsis plants exhibited enhanced tolerance, which was concomitant with the altered expression of stress/ABA-responsive genes, such as COR15a, COR47, ERD10, RD22, KIN1, ABI1, and ABI2. The resistance characteristics of ZmFKBP20-1 overexpression were associated with a significant increase in survival rate. These results suggested that ZmFKBP20-1 plays a positive role in drought and salt stress responses in Arabidopsis and provided new insights into the mechanisms of FKBP in response to abiotic stresses in plants.
