摘要: 外界环境对植物生长发育具有至关重要的影响, 然而近年来频繁出现的极端气候对植物生长发育产生了严重威胁。明确植物抗逆调控机制对保障植物生存和发育(特别是经济作物的产量)具有重要意义。基因可变剪接是一种重要的转录后调控机制, 对植物基因功能的多样性与抗逆性均具有重要作用。目前已在不同植物中鉴定出多种抗逆相关基因可变剪接体, 并阐明部分基因可变剪接介导的植物抗逆调控机制, 有效地推动了植物抗逆研究的相关理论基础。因此, 挖掘和鉴定更多抗逆基因在非生物胁迫下的可变剪接调控机制对植物抗逆研究具有重要意义。本文综述了植物基因可变剪接类型以及剪接机制, 重点阐述了非生物胁迫下相关基因可变剪接介导的植物抗逆研究进展, 展望了植物基因可变剪接研究方向。

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.
