  • Key message
    • Interestingly, the OsSRFP1-overexpressing plants were less tolerant to salt, cold and oxidative stresses than wild type plants; while the RNA interference silencing of OsSRFP1 plants were more tolerant than wild type without yield penalty
    • Knock-down of stress inducible OsSRFP1 encoding an E3 ubiquitin ligase with transcriptional activation activity confers abiotic stress tolerance through enhancing antioxidant protection in rice.
    • Taken together, our results demonstrate that OsSRFP1 may have dual functions in post-translational and transcriptional regulations in modulating abiotic stress responses in rice, at least in part, by negatively regulating antioxidant enzymes-mediated reactive oxygen species removal
    • OsSRFP1 was ubiquitously expressed in various rice organs, with the higher expression levels in roots, panicles and culm nodes
    • The transcript of OsSRFP1 was induced by cold, dehydration, salt, H2O2 and abscisic acid treatments
    • In vitro ubiquitination assays showed that OsSRFP1 possessed E3 ubiquitin ligase activity and the intact RING domain was essential for the activity
