Plant viruses are important pathogens able to overcome host defense mechanisms such as RNA silencing. We showed that the viral suppressor P19 affects the abundance of specific microRNAs in Physcomitrella, hence altering gene expression linked to key metabolic, signaling and developmental processes.
