摘要
AtATL78 is an Arabidopsis RING E3 ubiquitin ligase. RT-PCR and promoter-GUS assays revealed that AtATL78 was up-regulated by cold stress and down-regulated by drought. AtATL78 was localized at the plasma-membrane. Suppression of AtATL78 increased tolerance to cold stress but decreased tolerance to drought. Our data suggests that AtATL78 is a negative regulator of cold stress response and a positive regulator of drought stress response in Arabidopsis. These results further suggest that AtATL78 plays opposing roles in cold and drought stress responses.
