Abstract
- The DEAD-box family is the largest family of RNA helicases (RHs), playing crucial roles in RNA metabolism and plant stress resistance. In this study, we report that an RNA helicase, RH12, positively regulates plant salt tolerance, as rh12 knockout mutants exhibit heightened sensitivity to salt stress. Further analysis indicates that RH12 is involved in the abscisic acid (ABA) response, as rh12 knockout mutants show increased sensitivity to ABA. Examination of reactive oxygen species (ROS) revealed that RH12 helps inhibit ROS accumulation under salt stress during seed germination. Additionally, RH12 accelerates the degradation of specific germination-related transcripts. In conclusion, our results demonstrate that RH12 plays multiple roles in the salt stress response in Arabidopsis.<br />Competing Interests: Declaration of competing interest All authors disclosed no relevant relationships.<br /> (Copyright © 2024 Elsevier Inc.
