Plant noncoding RNA transcripts have gained increasing attention in recent years due to growing evidence that they can regulate developmental plasticity. In this review article, we comprehensively analyze the relationship between noncoding RNA transcripts in plants and their response to environmental cues. We first provide an overview of the various noncoding transcript types, including long and small RNAs, and how the environment modulates their performance. We then highlight the importance of noncoding RNA secondary structure for their molecular and biological functions. Finally, we discuss recent studies that have unveiled the functional significance of specific long noncoding transcripts and their molecular partners within ribonucleoprotein complexes during development and in response to biotic and abiotic stress. Overall, this review sheds light on the fascinating and complex relationship between dynamic noncoding transcription and plant environmental responses, and highlights the need for further research to uncover the underlying molecular mechanisms and exploit the potential of noncoding transcripts for crop resilience in the context of global warming.
近年来，由于越来越多的证据表明植物非编码 RNA 转录本可以调节发育可塑性，它们引起了人们的广泛关注。在这篇综述文章中，我们全面分析了植物中非编码 RNA 转录本与它们对环境信号的响应之间的关系。我们首先概述了各种非编码转录本类型，包括长链和小 RNA，以及环境如何调节它们的性能。然后，我们强调了非编码 RNA 二级结构对于其分子和生物学功能的重要性。最后，我们讨论了最近的研究，这些研究揭示了特定长非编码转录本及其在核糖核蛋白复合物中的分子伴侣在发育过程中以及对生物和非生物胁迫的响应中的功能意义。总的来说，这篇综述揭示了动态非编码转录与植物环境响应之间令人着迷且复杂的关系，并强调了需要进一步研究以揭示潜在的分子机制，并利用非编码转录本在全球变暖背景下提高作物抗逆性的潜力。
