UNASSIGNED: Although @entity2041 is famous for its reactive @entity26 species (ROS) scavenging function and plays a protective role in biotic stress, its regulatory function in abiotic stress still remains to be elucidated. Our previous study showed that exogenously applied @entity2041 ( @entity6172 ) could improve abiotic stress tolerance in @entity958 . Here, we report that endogenously increased @entity6172 also conferred tolerance to drought and salt stress in @entity958 . Moreover, both exogenous and endogenous @entity6172 delayed senescence and flowering time. Polysomal profiling results showed that global translation was enhanced after @entity6172 treatment and by the induced-increase of @entity6172 level by salt stress. By performing transcriptomic analyses of steady-state and polysome-bound mRNAs in @entity6172 -treated plants, we reveal that @entity6172 has a substantial impact on translation. Translational changes induced by @entity6172 treatment target numerous hormones and stress signaling molecules, which might contribute to the enhanced stress tolerance in @entity6172 -treated plants. Our translatome analysis also revealed that @entity2271 ( @entity2272 ), auxin and @entity7214 (JA) biosynthesis as well as signaling genes were activated during @entity6172 treatment, which has not been reported in previously published transcriptomic data. Together, our data suggest that the increased @entity2041 level results in stress tolerance and global translational changes. This article is protected by copyright. All rights reserved.
