Unraveling the role of Cullin3 of E3 ubiquitin ligase in salt stress tolerance via proteomics.

ABSTRACT:

Background

An association of OsCUL3c with salt tolerance has been found by a genome-wide association studies (GWAS) in rice. However, its functions and mechanisms remain unexplored. We aimed to examine the role of Cullin3 of E3 ubiquitin ligase in salt stress responses.

Results

Proteomic analyses were performed to compare the Atcul3a mutant and wild type (WT) plants under salt stress. Our results demonstrated that an Arabidopsis mutant of Cullin3a (Atcul3a), an OsCUL3c homolog, exhibits a more sensitive phenotype under salt stress than the WT. Differentially expressed proteins (DEPs) that were non-salt-responsive demonstrated an overrepresentation of Gene Ontology (GO) terms associated with photosynthesis. Conversely, salt-responsive DEPs exhibited enriched GO terms linked t
