Abstract: The external environment plays a crucial role in the growth and development of plants. However, the extreme climates that have occurred frequently in recent years have posed a serious threat to the growth and development of plants. Understanding the regulatory mechanisms of plant stress resistance is of great significance for ensuring the survival and development of plants (especially economic crops) and their yields. Alternative splicing is an important post-transcriptional regulatory mechanism and plays an important role in the diversity of plant gene functions and stress resistance. At present, a variety of alternative splicing variants of stress-resistant related genes have been identified in different plants, and some plant stress-resistant regulatory mechanisms mediated by alternative splicing of genes have been elucidated, effectively promoting the relevant theoretical basis for plant stress resistance research. Therefore, mining and identifying the alternative splicing regulatory mechanisms of more stress-resistant genes under abiotic stress play an important role in plant stress resistance research. This paper reviews the types and splicing mechanisms of alternative splicing of plant genes, focuses on expounding the research progress of plant stress resistance mediated by alternative splicing of related genes under abiotic stress and provides a prospect for the future direction of research on alternative splicing of plant genes.
