Outline
The external environment severely affects growth and development of plants. In recent years, the increasing extreme climates have posed a serious threat to the growth and development of plants. Understanding the regulatory mechanisms of plant stress tolerance 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 plant species, and several regulatory mechanisms involved in alternative splicing have been elucidated, effectively advancing the relevant theoretical basis for plant stress resistance in plants. This paper reviews the types and splicing mechanisms of alternative splicing in plants, highlights the recent progress in alternative splicing regulation of plant responses to abiotic stress, and provides a prospect for the future direction of research on alternative splicing in plants.
