Boosting salt tolerance is of high- priority in rice breeding. Given the significant challenges in this regard, one can spotlight the investigation of biological processes and stress responsive genes that are mainly involved in regulation of the complex trait of salinity tolerance in rice. One strategy in order to achieve this would be investigating the fundamental biological processes regulating salt tolerance. However, the knowledge on the significant biological processes involving in salt tolerance is very limited. To this end, a comparative analysis of the extremely tolerant and extremely sensitive recombinant inbred lines bulks produced from a cross involving salt-tolerant variety CSR 27 and salt-sensitive variety MI 48 was performed using microarray data analysis, Gene Ontology (GO) biological process enrichment and network analysis. According to the GO enrichment analysis results, the tolerance of tolerant recombinant inbred lines seems to be related to the metabolic process, cellular process, cellular biosynthetic process, biosynthetic process, gene expression, cellular macromolecule biosynthetic process, macromolecule biosynthetic process, protein metabolic process, cellular protein metabolic process, translation, generation of precursor metabolites and energy, transport, establishment of localization, localization, and photosynthesis biological processes. Network analysis of differentially expressed genes revealed LOC_Os01g64660 and LOC_Os03g16030 as critical genes in salt and control conditions, respectively. These genes may serve as crucial genes that may be contributing to salt tolerance. The knowledge and insights gained from this research might provide the opportunity towards a more detailed understanding of the biological processes affecting salinity tolerance
