Suppression of Arabidopsis RING E3 ubiquitin ligase AtATL78 increases tolerance to cold stress and decreases tolerance to drought stress.

Highlights: [•] AtATL78 is an Arabidopsis plasma-membrane-localized RING E3 ubiquitin ligase. [•] AtATL78 was up-regulated by cold stress and, in contrast, down-regulated by drought. [•] Suppression of AtATL78 increases tolerance to cold stress. [•] Suppression of AtATL78 decreases tolerance to drought stress. [•] AtATL78 plays opposing roles in cold and drought stress responses in Arabidopsis. [ABSTRACT FROM AUTHOR]
