Fig mosaic virus (FMV), a member of the newly formed genus Emaravirus, is a segmented negative-strand RNA virus. Each of the six genomic FMV segments contains a single open reading frame: that of RNA4 encodes the protein p4. FMV-p4 has been suggested to be the movement protein (MP) of the virus; however, direct experimental evidence for this is lacking. We assessed the intercellular distribution of FMV-p4 in plant cells by confocal laser scanning microscopy, and we found that FMV-p4 was localized to plasmodesmata and to the plasma membrane accompanied by tubule-like structures. A series of experiments designed to examine the movement functions revealed that FMV-p4 has the capacity to complement viral cell-to-cell movement, prompt sGFP diffusion between cells, and spread by itself to neighboring cells. Altogether, our findings demonstrated that FMV-p4 shares several properties with other viral MPs and plays important role in cell-to-cell movement.
