Triticum aestivum L., commonly known as wheat, has long been considered one of the most important crops worldwide. Over the past 20 years, there has been a notable increase in domestic demand for wheat in South Korea, raising interest in locally grown varieties. In recent years, an expansion in reclaimed land areas has prompted extensive research into crop breeding and varietal improvement for salt tolerance. As part of this research effort, salt-tolerant mutant individuals selected through gamma radiation mutation were used as experimental materials to study the temporal gene expression profiles related to salt response in "Urimil" varieties following salt treatment. In this study, physiological analyses were conducted by measuring the changes in the Na⁺ and K⁺ contents, as well as the K⁺/Na⁺ ratios, in plant leaves as indicators of salt response. RNA-Seq was used to analyze gene expression patterns post-salt treatment across different time points. Furthermore, gene ontology compartmentalized the genes into biological processes, molecular functions, and cellular components. Finally, the wheat reference genome was compared with the experimental and control groups to identify non-synonymous SNPs that could induce changes in protein expression. This analysis aimed to investigate the mechanisms of salt tolerance in wheat and to identify candidate genes for further research.
