Bidens mottle virus (BiMoV) is a pathogenic plant virus in the plant virus family Potyviridae. BiMoV is a flexuous filamentous particle, 720 nm long, and belongs to the Potyviridae genus Potyvirus. Like other viruses in this genus, Bidens mottle virus is transmitted both mechanically by sap and by aphids in a stylet-borne fashion. B. pilosa can be doubly infected with BiMoV and a second virus called (SYNV). SYNV is asymptomatic in B. pilosa but it enhances the symptoms of BiMoV in this plant when both viruses are present.)
