Pseudouridine (Ψ) is a modified nucleoside present in diverse RNA species, including mRNA (messenger RNA), snRNA (small nuclear RNA), rRNA (ribosomal RNA) and tRNA (transfer RNA). In plants, Ψ serves a critical function in RNA modification, supporting the stability, structural integrity, and functionality of RNA molecules. This review provides the various roles that Ψ fulfils in the modification of plant RNA biology, encompassing effects on biosynthesis pathways, regulatory mechanisms, stability, and translation efficiency. Additionally, we discuss recent advancements in the dynamic regulation of Ψ deposition in response to environmental stimuli and stressors. Elucidating Ψ's roles contributes to the comprehension of plant biology and may facilitate developments in biotechnology and crop improvement.
假尿苷（Ψ）是一种存在于多种RNA种类中的修饰核苷，包括信使RNA（mRNA）、小核RNA（snRNA）、核糖体RNA（rRNA）和转运RNA（tRNA）。在植物中，Ψ在RNA修饰中发挥关键作用，支持RNA分子的稳定性、结构完整性和功能。本综述阐述了Ψ在植物RNA生物学修饰中所起的各种作用，包括对生物合成途径、调控机制、稳定性和翻译效率的影响。此外，我们还讨论了在响应环境刺激和应激源时，Ψ沉积动态调控方面的最新进展。阐明Ψ的作用有助于理解植物生物学，并可能促进生物技术和作物改良的发展。
