Recent studies reported a significant contribution of microRNAs (miRNAs) in plant response to elicitors. The aim of our study was to analyse the effect of exogenously applied plant-derived elicitor cobalt-diglycyrrhizinate on Triticum aestivum L. genome based on the functional characterization of stress associated miRNAs. Our results confirmed the impact of cobalt-diglycyrrhizinate on plant genome in a way of plant response stimulation via expression of stress-related miRNAs markers. We found that both miRNAs markers (miR168 and miR395) are involved in response to plant-based elicitor stimuli. The role of miR168 and miR395 as functional markers sensitive to applied elicitors has been confirmed. Marker miR168 is suitable for the mapping of plant genome response to native elicitor, lower concentration of an elicitor is more suitable for plant immune system stimulation and its inappropriate concentrations may be toxic to the plant. Plant genome very sensitively reacts to elicitor stimuli and the question of the appropriate concentration and the time point of elicitor application are crucial.

小麦基因组中使用microRNA标记的植物激发子效应的分子表征

最近的研究报道了微小RNA(miRNA)在植物对激发子的应答中的重要贡献。我们研究的目的是分析外源施加的植物激发子二甘草酸钴对小麦的影响L.基因组基于应激相关miRNA的功能表征。我们的结果证实了二甘草酸钴对植物基因组的影响是通过胁迫相关miRNA标记的表达来刺激植物的反应。我们发现两个miRNA标记(miR168和miR395)都参与了对基于植物的激发子刺激的响应。已经确认了miR168和miR395作为对施加的引发子敏感的功能标记的作用。标记miR168适用于植物基因组对天然激发子的反应作图,较低浓度的激发子更适合植物免疫系统的刺激,其浓度过高可能对植物有毒。
