The important roles of members in regulating abiotic and biotic stress tolerance have been demonstrated in many plants. However, fewer studies have explored the gene family and its role in the salt stress response in barley, a crop known for its superior salt tolerance compared to other major cereals. Here, we identified a total of 109 putative genes (nine , eight , 92 ) in barley. Promoter analysis of suggested that HvDJs might be involved in the processes of hormone regulation and stress response. Tandem and segmental duplications appear to be the driving forces behind gene family expansion. RNA-seq analysis showed that the expression of 37 was salt-induced, and , , and were the most differentially expressed under salt stress. Protein-protein interaction analysis indicated that HvDJA09 and HvDJA05 play core roles in the complex regulatory network. Taken together, the current study provides valuable information for a deeper understanding of the function of in regulating salt stress tolerance in barley.
成员在调节非生物和生物胁迫耐受性方面的重要作用已在许多植物中得到证实。然而，较少有研究探索大麦中该基因家族及其在盐胁迫响应中的作用，大麦是一种与其他主要谷物相比具有较强耐盐性的作物。在此，我们在大麦中总共鉴定出109个假定的该基因（9个该基因、8个该基因、92个该基因）。对该基因的启动子分析表明，HvDJs可能参与激素调节和胁迫响应过程。串联重复和片段重复似乎是该基因家族扩张的驱动力。RNA测序分析表明，37个该基因的表达受盐诱导，并且在盐胁迫下，该基因、该基因、该基因和该基因的表达差异最为显著。蛋白质-蛋白质相互作用分析表明，HvDJA09和HvDJA05在复杂的调控网络中发挥核心作用。综上所述，本研究为更深入了解该基因在调节大麦耐盐性中的功能提供了有价值的信息。
