The important roles of JDP members in regulating abiotic or biotic stress tolerance have been demonstrated in many plants. However, limited studies have explored the JDP gene family and its role in salt stress response in barley, a crop known for its superior salt tolerance compared to other major cereals. Here, we totally identified 109 putative JDP genes (9 HvDJAs, 8 HvDJBs, 92 HvDJCs,) in barley. Promoter analysis of HvDJs suggested that HvDJs might be involved in the processes of hormone regulation and stress response. Tandem and segmental duplication should be the driving force for JDP gene family expansion. RNA-seq analysis showed that the expressions of 37 HvDJs were salt-induced, and HvDJB06, HvDJC58 and HvDJC59 were the most differentially expressed under salt stress. Protein-protein interaction analysis indicated that HvDJA09 and HvDJA05 play the core roles in complex regulatory network. Taken together, the current study provided the valuable information for deep understanding of the function of HvDJs in regulating salt stress tolerance in barley.
