甲基转移酶 ATMETTL5 写入 18S 核糖体 RNA 上的 m6A 以调节拟南芥的翻译。
RNA 的异常修饰可导致植物基因表达失调和生长受阻。核糖体 RNA(rRNA)占总 RNA 的很大一部分,而植物中 rRNA 修饰的确切功能和分子机制在很大程度上仍然难以捉摸。在这里,我们阐明了典型的 RNA 修饰 N6-甲基腺苷(m6A)只存在于 18S rRNA 中,而不存在于 25S rRNA 中。我们发现了一种完全未定性的蛋白质--ATMETTL5--拟南芥 m6A 甲基转移酶,它负责在 18S rRNA 的 1771 位点安装 m6A 甲基化装置。ATMETTL5 在细胞核和细胞质中普遍表达和定位,介导 rRNA m6A 甲基化。从机理上讲,ATMETTL5介导的甲基化缺失会导致翻译减弱。此外,我们还发现了 ATMETTL5 介导的甲基化在协调蓝光介导的下胚轴生长中的作用,即调节蓝光相关信使 RNA(mRNA)(特别是 HYH 和 PRR9)的翻译。我们的发现从机理上揭示了 rRNA 修饰如何调控 mRNA 翻译中的核糖体功能以及对蓝光的响应,从而加深了我们对表观遗传修饰在精确调控植物 mRNA 翻译中的作用的理解。

期刊介绍: New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
