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。
MicroRNAs are a class of endogenous small molecule non-coding RNA that regulates gene expression through the degradation or suppression of translation of its target genes, thereby regulating plant physiological activities. When plants encounter stress, miRNAs act on genes associated with stress and activate the body’s resistance mechanisms against unfavorable factors. The continuous cropping obstacle of Rehmannia glutinosa is also a kind of stress. Studying on the level of miRNAs is helpful to understand the molecular mechanism of Rehmannia. This review summarizes the functions of miRNAs in Rehmannia glutinosa and their regulatory mechanisms, and prospects the miRNAs in Rehmannia glutinosa.
