菠菜rna模拟GFP (S-RMG)已成功用于监测细胞rna,包括细菌,酵母和人类细胞中的microrna。然而,S-RMG尚未在植物中得到证实。在这项研究中,我们发现,与细菌、酵母和人类细胞tRNAs一样,植物tRNAs(如tRNALys)可以保护和/或稳定菠菜RNA适体与荧光团DFHBI的相互作用,从而发出可检测水平的绿色荧光。trnalys -菠菜- trnalys一旦进入“无叶绿体”洋葱表皮细胞,在DFHBI的存在下可以发出强烈的绿色荧光。我们的研究结果首次证明了基于菠菜的RNA可视化具有在植物细胞中监测RNA的潜力。在线版本包含补充材料,可在10.1007/s10142-022-00835-x获得。
Spinach RNA-mimicking GFP (S-RMG) has been successfully used to monitor cellular RNAs including microRNAs in bacterium, yeast, and human cells. However, S-RMG has not been established in plants. In this study, we found that like bacterial, yeast, and human cellular tRNAs, plant tRNAs such as tRNALys can protect and/or stabilize the Spinach RNA aptamer interaction with the fluorophore DFHBI enabling detectable levels of green fluorescence to be emitted. The tRNALys-Spinach-tRNALys, once delivered into “chloroplast-free” onion epidermal cells can emit strong green fluorescence in the presence of DFHBI. Our results demonstrate for the first time that Spinach-based RNA visualization has the potential for in vivo monitoring of RNAs in plant cells.
