摘要

自从在转运RNA (tRNAs)和核糖体RNA (RNAs)中首次发现核糖核酸(RNA)修饰以来,科学家们一直在寻求破译生物系统中RNA修饰的身份和功能。在过去的十年中,在植物生物学领域中,对RNA修饰功能进行表征和评估的研究数量有了巨大的增长。由于这些研究,我们现在根据它们的化学性质和发现它们的RNA,以及参与从RNA分子中添加,读取和去除它们的过程的一系列蛋白质,对RNA修饰进行分类。除了它们的身份之外,这个谜题的另一个关键部分是各种类型的RNA修饰的功能意义。在这里,我们阐明了最近的研究,这些研究有助于建立我们目前对植物转录组中发现的RNA修饰多样性的理解,以及它们在分子(例如RNA稳定性,翻译和运输)和生物体(例如应激反应和发育)水平上发挥的功能。最后,我们考虑了与植物基因表达和生物学相关的关键研究问题,并强调了各种技术的发展,这些技术正在推动我们在这一研究领域的见解。

The Diversity and Functions of Plant RNA Modifications: What We Know and Where We Go from Here.

Since the discovery of the first ribonucleic acid (RNA) modifications in transfer RNAs (tRNAs) and ribosomal RNAs (rRNAs), scientists have been on a quest to decipher the identities and functions of RNA modifications in biological systems. The last decade has seen monumental growth in the number of studies that have characterized and assessed the functionalities of RNA modifications in the field of plant biology. Owing to these studies, we now categorize RNA modifications based on their chemical nature and the RNA on which they are found, as well as the array of proteins that are involved in the processes that add, read, and remove them from an RNA molecule. Beyond their identity, another key piece of the puzzle is the functional significance of the various types of RNA modifications. Here, we shed light on recent studies that help establish our current understanding of the diversity of RNA modifications found in plant transcriptomes and the functions they play at both the molecular (e.g., RNA stability, translation, and transport) and organismal (e.g., stress response and development) levels. Finally, we consider the key research questions related to plant gene expression and biology in general and highlight developments in various technologies that are driving our insights forward in this research area.
