Small RNAs: Efficient and miraculous effectors that play key roles in plant–microbe interactions

Plants' response to pathogens is highly complex and involves changes at different levels, such as activation or repression of a vast array of genes. Recently, many studies have demonstrated that many RNAs, especially small RNAs (sRNAs), are involved in genetic expression and reprogramming affec...

Description
Summary:Plants' response to pathogens is highly complex and involves changes at different levels, such as activation or repression of a vast array of genes. Recently, many studies have demonstrated that many RNAs, especially small RNAs (sRNAs), are involved in genetic expression and reprogramming affecting plant–pathogen interactions. The sRNAs, including short interfering RNAs and microRNAs, are noncoding RNA with 18–30 nucleotides, and are recognized as key genetic and epigenetic regulators. In this review, we summarize the new findings about defence‐related sRNAs in the response to pathogens and our current understanding of their effects on plant–pathogen interactions. The main content of this review article includes the roles of sRNAs in plant–pathogen interactions, cross‐kingdom sRNA trafficking between host and pathogen, and the application of RNA‐based fungicides for plant disease control. This review summarizes the effects of small RNAs (sRNAs) on plant–pathogen interactions and the recent discoveries of cross‐kingdom sRNA trafficking, and discusses the possibility of using RNA‐based fungicides for plant protection.
