Abstract:
MicroRNAs (miRNAs) are a class of noncoding RNAs that play important roles in regulating gene expression. They are involved in various biological processes, including plant growth, development, hormone signalling pathways and defence responses. Numerous studies have demonstrated the crucial role of miRNA in modulating plant immunity against various pathogens, including fungi, bacteria, viruses, nematodes and oomycetes. In this review, we synthesise recent advances in defence-related miRNAs in response to pathogens, highlighting their effects on plant-pathogen interactions and their functions in regulating hormone signalling pathways. Additionally, we explore the potential of small RNA-based technology tools in protecting plants from pathogens, including artificial microRNA, synthetic trans-acting small interfering RNA and RNA interference techniques, such as spray-induced gene silencing, host-induced gene silencing and virus-induced gene silencing.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
