Abstract:
Small RNAs are involved in a multitude of biological processes in plants. Based on their origins and precursor structures, small RNAs can be divided into two major classes: microRNAs (miRNAs) and small interference RNAs (siRNAs). Small RNAs are typically 21-24 nucleotide (nt) long, and differ in both biogenesis and biological function. In the pathogenic process, pathogens can either induce or suppress the synthesis of small RNAs, which, in turn, regulate the expression of pathogenesis-related genes to mediate diverse plant-pathogen interactions. The biogenesis and biological functions of small RNAs, together with possible regulation mechanisms underlying the host-pathogen interactions, are summarized in this review.

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...

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
