Here, we assessed the expression patterns and functional roles of two RNA helicases, AtRH9 and AtRH25, in Arabidopsis thaliana under abiotic stress conditions. The transcript levels of AtRH9 and AtRH25 were up-regulated markedly in response to cold stress, whereas their transcript levels were down-regulated by salt or drought stress. Phenotypic analysis of the transgenic plants and T-DNA-tagged mutants showed that the constitutive overexpression of AtRH9 or AtRH25 resulted in the retarded seed germination of Arabidopsis plants under salt stress conditions. AtRH25, but not AtRH9, enhanced freezing tolerance in Arabidopsis plants. Both AtRH9 and AtRH25 complemented the cold-sensitive phenotype of BX04 Escherichia coli mutant cells, but AtRH25 had much more prominent complementation ability than AtRH9. An in vitro nucleic acid binding assay showed that AtRH9 binds equally to all homoribopolymers, whereas AtRH25 binds preferentially to poly(G). Taken together, these results demonstrate that AtRH9 and AtRH25 impact on the seed germination of Arabidopsis plants under salt stress conditions, and suggest that the difference in cold tolerance capability between AtRH9 and AtRH25 arises from their different nucleic acid-binding properties."xsd:string |
