Throughout their lives, plants sense many developmental and environmental stimuli, and activation of optimal responses against these stimuli requires extensive transcriptional reprogramming. To facilitate this activation, plant mRNA contains untranslated regions (UTRs) that significantly increase the coding capacity of the genome by producing multiple mRNA variants from the same gene. In this review we compare UTRs of arabidopsis (Arabidopsis thaliana) and rice (Oryza sativum) at the genome scale to highlight their complexity in crop plants. We discuss different modes of UTR-based regulation with emphasis on genes that regulate multiple plant processes, including flowering, stress responses, and nutrient homeostasis. We demonstrate functional specificity in genes with variable UTR length and propose future research directions.

植物基因表达的UTR依赖性控制
植物在其整个生命中都会感觉到许多发育和环境刺激,而针对这些刺激的最佳响应的激活需要大量的转录重编程。为了促进这种激活,植物mRNA包含非翻译区(UTR),该区域通过从同一基因产生多个mRNA变体来显着提高基因组的编码能力。在这篇综述中,我们比较了拟南芥(Arabidopsis thaliana)和水稻(Oryza sativum)的UTR。),以突出其在农作物中的复杂性。我们讨论了基于UTR的不同调控模式,重点是调控多种植物过程的基因,包括开花,胁迫反应和养分稳态。我们展示了具有可变UTR长度的基因的功能特异性,并提出了未来的研究方向。
