Plant growth and productivity are largely affected by environmental stresses. Therefore, plants have evolved unique adaptation mechanisms to abiotic stresses through fine-tuned adjustment of gene expression and metabolism. Recent advanced technologies, such as genome-wide transcriptome analysis, have revealed that a vast amount of non-coding RNAs (ncRNAs) apart from the well-known housekeeping ncRNAs such as rRNAs, tRNAs, small nuclear RNAs (snRNAs) and small nucleolar RNAs (snoRNAs) are expressed under abiotic stress conditions. These various types of ncRNAs are involved in chromatin regulation, modulation of RNA stability and translational repression during abiotic stress response. In this review, we summarize recent progress that has been made on ncRNA research in plant abiotic stress response.
植物的生长和生产力在很大程度上受到环境压力的影响。因此，植物通过精细调节基因表达和代谢，进化出了独特的适应机制来应对非生物胁迫。最近的先进技术，如全基因组转录组分析，揭示了大量非编码 RNA（ncRNA）的存在，除了众所周知的管家 ncRNA，如 rRNA、tRNA、小核 RNA（snRNA）和小核仁 RNA（snoRNA），在非生物胁迫条件下也有表达。这些不同类型的 ncRNA 参与了染色质调节、RNA 稳定性的调节以及非生物胁迫响应过程中的翻译抑制。在这篇综述中，我们总结了植物非生物胁迫响应中 ncRNA 研究的最新进展。
