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.

Key words: microRNA, Resistance of Rice, Abiotic Stress, Target Genes, Transcriptome
