Rice growth and development are significantly affected by salt stress. Exploring salt stress-tolerant genes and their regulatory pathways is essential for sustaining productivity and ensuring food security. The brassinazole-resistant 1 (BZR1)/BRI1-EMS1 suppressor (BES1) transcription factors play pivotal roles in regulating plant development and stress responses. However, studies specifically linking BZR1 to salt tolerance in rice remain limited. In this study, 33 predicted common differentially expressed genes (cDEGs) interacting with BZR1 were identified and functionally characterized to encounter salt stress in rice. The phylogenetic relationship analysis revealed a strong evolutionary relationship between these rice genes and known Arabidopsis salt-tolerant genes. Gene ontology (GO) enrichment further confirmed that the cDEGs are significantly associated with key biological processes involved in the rice salt stress response. RNA-Seq results revealed distinct expression patterns of cDEGs between shoots and roots. In the shoots, 22 cDEGs were up-regulated, while 11 were down-regulated. In the roots, 14 cDEGs were up-regulated and 19 were down-regulated. This indicates tissue-specific regulatory responses under the experimental conditions. These findings highlight the differential regulatory roles of BZR1 across tissues under salt stress conditions. Overall, this study offers new insights into the molecular mechanisms underlying BZR1-mediated salt tolerance and identifies promising candidate genes for future experimental validation and the development of salt-tolerant rice cultivars.
