520 |a Salinity is a major limitation factor for crop productivity worldwide. DREB transcription factors broadly participate in plant stress response and have been extensively identified in a wide variety of plants. In this study, we characterized and analyzed the function of a novel A-5 type DREB gene ScDREB8 from the desiccation tolerant moss Syntrichia caninervis. Yeast one-hybrid experiment showed that ScDREB8 had no transactivation activity. Transient expression assay in onion epidermal cells revealed that ScDREB8 is distributed throughout the cell with no apparent specificity. Overexpression of ScDREB8 significantly increased the germination rate of Arabidopsis under salt stress and improved the salt tolerance of Arabidopsis at the seedling stage by up-regulating the expression of downstream stress-related genes and improving ROS scavenging ability. ScDREB8 is a promising candidate gene for improving crop salt stress and will provide greater insight to the molecular mechanism of stress tolerance of A-5 type DREB proteins
