摘　　要：MicroRNAs是一类内源性小分子的非编码RNA,它通过对其靶基因的降解或抑制翻译来调控基因表达,进而调控植物的生理活动。植物在遇到逆境胁迫时,miRNAs会作用于与逆境相关的基因,启动体内的抗逆机制抵抗不利因素。地黄的连作障碍也是一种胁迫,从miRNAs水平上研究,有利于解读地黄连作障碍的分子机制。该文对地黄体内miRNAs的功能及调控机制进行了综述,并对miRNAs在地黄的研究中进行了展望。The efficacy of Rehmannia glutinosa which as a large quantity of traditional Chinese medicine is significant. However, the land must be given up after one season of R. glutinosa cultivation or replanted after a period of 8-10 years because of the severe continuous cropping obstacles. MicroRNAs is a class of endogenous non-coding small RNAs, which participate in regulation of physiological activities by target mRNA cleavage or translational repression in plants. In recent years, studies on the role of miRNAs in plants have made significant progresses, especially in medicinal plants. MiRNAs from some different medicinal plant species have been identified with regulatory effects. When plants are exposed to environmental stress, miRNAs act on stress-related genes and initiate stress-resistance mechanisms in the body against adverse factors. R. glutinosa is also a kind of environmental stress. It is conducive to deciphe ring the molecular mechanism of continuous cropping obstacles for us by researching miRNAs. This article reviews the production of miRNAs, mechanism, research approaches and characteristics of resisting the environmental stresses in plants, the development trends and future prospect of R. glutinosa miRNAs research.
