physiological function | at the seed germination stage, a loss-of-function mutant is hypersensitive to abscisic acid, salt and mannitol stresses, whereas isoform CLO4-overexpressing lines are more hyposensitive to those stresses than the wild type. In adult stage, loss-of-function mutant and overexpressing plants show enhanced and decreased drought tolerance, respectively. Following exposure to exogenous abscisic acid, the expression of key abscisic acid-dependent regulatory genes, such as ABF3 and ABF4, is up-regulated in the loss-of-function mutant, while it is down-regulated in overexpressing lines | Arabidopsis thaliana |
