DESCRIPTION:Plasmodesmata are channels between cells which provide a pathw
 ay for exchange of macromolecules involved in development\, metabolism\, d
 efense. Plant viruses have been used as tools to understand the mechanisms
  available for cell-to-cell movement of macromolecules between cells. Towa
 rd this research\, our laboratory uses Potato virus X which encodes three 
 proteins to enable viral cell-to-cell movement. Two of these proteins inte
 ract with the ER and one protein is a silencing suppressor. Our recent inv
 estigations have shown that the ER plays an important role in virus cell-t
 o-cell movement. ER stress is also triggered by virus infection and seems 
 to be a factor modulating accumulation of viral movement proteins. \n\nhtt
