RNA regulatory processes such as transcription, degradation and stabilization control are the major mechanisms that determine the levels of mRNAs in plants. Transcriptional and post-transcriptional regulations of RNAs are drastically altered during plant stress responses. As a result of these molecular processes, plants are capable of adjusting to changing environmental conditions. Understanding the role of these mechanisms in plant stress responses is important and necessary for the engineering of stress-tolerant plants. Recent studies in the area of RNA regulation have increased our understanding of how plants respond to environmental stresses. This review highlights recent progress in RNA regulatory processes that are involved in plant stress responses, such as small RNAs, alternative splicing, RNA granules and RNA-binding proteins. This article is part of a Special Issue entitled: Plant gene regulation in response to abiotic stress.
诸如转录、降解和稳定性控制等RNA调控过程是决定植物中mRNA水平的主要机制。在植物应激反应过程中，RNA的转录调控和转录后调控会发生剧烈变化。这些分子过程使植物能够适应不断变化的环境条件。了解这些机制在植物应激反应中的作用对于培育抗逆植物至关重要且必不可少。RNA调控领域的最新研究增进了我们对植物如何应对环境胁迫的理解。本综述重点介绍了参与植物应激反应的RNA调控过程的最新进展，如小RNA、可变剪接、RNA颗粒和RNA结合蛋白。本文是名为“植物对非生物胁迫的基因调控”特刊的一部分。
