Abstract:

Ubiquitination is an important process related to the activities of enzymes which occurs in the post-translational modification stage. This process requires for the regulation of divers cellular functional through biological events including the response to hormone, apoptosis and abiotic stress. In this study, we characterized the biology functional of AtEUL(Arabidopsis thaliana E3 Ubiquitin Ligase 1) in ethanol response. The initial result showed that, the mRNA level of AtEUL1 was dramatically induced by ethanol exogenous application. The transgenic plants overexpressing AtEUL1 were hypersensitive to ethanol response than wild-type during dark-grown seedling growth, whereas the ateul1 mutant was hypersensitive, indicating that AtEUL1 negatively regulates ethanol-mediated response of early dark-grown seedling growth. Additionally, the ateul1 mutant was significantly influential in ethanol sensitive parameters including hypocotyl length and the expression of ethanol metabolic genes. The taken together, the result suggests that AtEUL1, a ligase E3 enzyme, plays a function as ethanol regulator response in early seedling dark-grown of Arabidopsis development.
