miR172调控植物生长发育及逆境胁迫的研究进展

microRNA(miRNA)是一类内源性非编码小RNA,在植物整个生长发育过程中都起着重要作用,是基因表达的重要调控因子,而microRNA172(miR172)是众多miRNA家族中的重要的一员。为了更直观的认识miR172在植物中所发挥的作用,笔者归纳和总结了miR172在调控植物生长发育过程和响应逆境的研究进展,具体分析了miR172在植物营养生长阶段转变、开花、花器官发育、节间长度、植物商品器官发育以及逆境胁迫响应等诸多过程中发挥的作用。笔者认为miR172在植物中仍有很多未知的功能尚未发掘,因此未来深入挖掘和研究miR172在植物生长过程中更多的作用是一个重要的研究方向,在此基础上深入解析miR172在此过程中的功能、分子调控机制,为人为利用miR172调控植物生长发育奠定理论基础。

Plant Growth and Development and Response to Adversity Stress Regulated by miR172: A Review

microRNA (miRNA) is a kind of endogenous non-coding small RNA, it plays significant role in the whole process of plant growth and development, and it is an important regulator in the gene expression. miR172 is an important member among various miRNA families. In order to understand the role of miR172 in plants more intuitively, the authors classified and summarized the research progress of miR172 in regulating plant growth and development, as well as plant response to adversity stress. miR172 is involved in many processes, such as vegetative phase transition, flowering, floral organ development, internode length, plant commodity organs’ development and plant response to adversity stress. The authors think that miR172 still has many unknown functions in plants. Therefore, it is an important research direction to deeply explore more roles of miR172 in plant growth process in the future. Based on this, the function and molecular regulation mechanism of miR172 should be deeply analyzed, which will lay a theoretical foundation for artificially using miR172 to regulate plant growth and development.
