N6-methyladenosine(m6A)is the most abundant form of post-transcriptional chemical modification of RNA in eukaryotic mRNA.The m6A-modified RNAs are mainly regulated by the m6A methyltransferases(writers),demethyltransferases(erasers)and reader proteins(readers).In recent years,m6A methylation has been found to play diverse roles in plant virus infection,and the related regulatory mechanisms are being investigated.This review outlines the basic components of m6A modification-related proteins in plants,the development of m6A detection technology,and the current progress of m6A methylation in the interactions between plants and viruses.A new perspective of the m6A methylation-dependent research in plants and plant RNA viruses is also provided.
