| 摘 要： | microRNA作为最新发现一类遗传物质,在水稻抗逆性上起到重要作用。为深入了解miRNA在水稻抗逆机制中的作用,本研究归纳了水稻体内在抗旱、抗冷害、抗病虫害、抗重金属危害4个方面中起到重要作用的miRNAs,总结了部分已知miRNAs的调控水稻抗逆机理。通过查阅数篇相关文献笔者发现,目前仍有大量miRNAs未被检测到,而且已检测到的miRNAs中还有很多未探清的作用原理。miRNA是有效调控基因的手段之一,将其合理可行地运用在水稻抗逆性育种中还需专业人士的努力探索。

| Abstract: | microRNAs are a group of newly discovered genetic materials and play an important role in rice stress resistance. In order to further research the functions of miRNA in rice stress resistance, this study reviewed the role of miRNAs in drought resistance, cold injury resistance, disease and insect pest resistance, and heavy metal resistance of rice, and summarized the mechanism of some miRNAs that regulated rice resistance. It is found that there are still lots of miRNAs that have not been detected, and many functional mechanisms of the known miRNAs have not been clarified. miRNAs are one of the effective means of gene regulation, and their reasonable and feasible application in rice stress resistance breeding still needs more exploration. |
