Summary and Concluding Remarks by the Second Session

Abstract

It is now an accepted fact that most plant viruses code for proteins that potentiate their movement from cell-to-cell in their hosts. This is an important phenomenon, not only because of its intrinsic interest in our understanding of virus movement, but because it has practical importance in explaning some forms of viral resistance; i.e., some plants are resistant to the disease that a virus might cause because the virus is unable to move from the initially-infected cells.
