Significant progress has been made in research on stress tolerance trait genes of wheat crops, which has greatly promoted the development of crop improvement and food security. Through high-throughput sequencing technology and genome-wide association analysis (GWAS), researchers have successfully identified multiple key genes and regulatory networks related to stress response, especially under stress conditions such as drought, salinity, and low temperature. The application of gene editing technologies, such as CRISPR/Cas9, provides new strategies for precisely improving stress tolerance traits. At the same time, the development of phenomics has deepened the understanding of crop stress response mechanisms. Future research will focus on the application of systems biology methods, integrating multi-omics data to reveal complex stress tolerance mechanisms; using precision breeding technology to precisely operate stress tolerance genes ; strengthening research on the interaction between environment and genetics, and exploring the genetic diversity of wild resources. and promote international cooperation and knowledge sharing. These directions will provide a solid scientific basis for cultivating wheat crop varieties with high stress tolerance to cope with climate change and global food security challenges.
