Soybean vein necrosis orthotospovirus can move systemically in soybean in the presence of bean pod mottle virus.

Soybean vein necrosis virus (SVNV), the causal agent of the homonymous disease, is a ubiquitous virus in North America. The widespread presence of the virus has led to the hypothesis that mixed infections with other viruses could alter disease symptoms, localization in the plant and even epidemiology. The potential interaction between bean pod mottle virus (BPMV), soybean mosaic virus (SMV), the most economically important soybean viruses in the U.S., and SVNV was assessed in the work presented here. Results revealed that soybean, a local lesion host for SVNV, becomes permissive in the presence of BPMV; whereas there where no obvious interactions observed in mixed infections with SMV.
