High-resolution microscopy of whole plant cells reveals virus-induced changes to intercellular connectivity
Plasmodesmata (PD) provide plant viruses a direct route for cell-to-cell spread. Viral infection increases intercellular trafficking via PD, termed gating, but the mechanism involved remains unclear. Here, using a combination of high-resolution volume electron microscopy and live cell imaging, we demonstrate that diverse viruses increased the number of PD in infected leaves. This increase was…
