There is growing evidence that post-transcriptional RNA modifications are highly dynamic and can be used to improve crop production. Although more than 172 unique types of RNA modifications have been identified throughout the kingdom of life, we are yet to leverage upon the understanding to optimize RNA modifications in crops to improve productivity. The contributions of internal mRNA modifications such as N6-methyladenosine (m6A) and 5-methylcytosine (m5C) methylations to embryonic development, root development, leaf morphogenesis, flowering, fruit ripening and stress response are sufficiently known, but the roles of the two most abundant RNA modifications, pseudouridine (Ψ) and 2′-O-methylation (Nm), in the cell remain unclear due to insufficient advances in high-throughput technologies in plant development. Therefore, in this review, we discuss the latest methods and insights gained in mapping internal Ψ and Nm and their unique properties in plants and other organisms. In addition, we discuss the limitations that remain in high-throughput technologies for qualitative and quantitative mapping of these RNA modifications and highlight future challenges in regulating the plant epitranscriptome.

植物表观转录组:重访假尿苷和 2'-O-甲基 RNA 修饰

越来越多的证据表明转录后 RNA 修饰具有高度动态性,可用于提高作物产量。尽管在整个生命王国中已经确定了超过 172 种独特类型的 RNA 修饰,但我们尚未利用这些知识来优化作物中的 RNA 修饰以提高生产力。N6-甲基腺苷 (m 6 A) 和 5-甲基胞嘧啶 (m 5 C) 甲基化等内部 mRNA 修饰对胚胎发育、根系发育、叶片形态发生、开花、果实成熟和应激反应的贡献已广为人知,但作用两种最丰富的 RNA 修饰,假尿苷 (Ψ) 和 2'- O由于植物发育中高通量技术的进展不足,细胞中的-甲基化(Nm)仍不清楚。因此,在这篇综述中,我们讨论了在绘制内部 Ψ 和 Nm 及其在植物和其他生物体中的独特特性方面的最新方法和见解。此外,我们讨论了高通量技术在对这些 RNA 修饰进行定性和定量映射方面仍然存在的局限性,并强调了未来在调节植物表观转录组方面的挑战。
