Molecular studies of the synergistic interactions between plum pox virus HC-Pro protein and potato virus X.

Archives of virology - 1 Dec 2002

Yang S, Ravelonandro M

Abstract excerpt

Helper component proteinase (HC-Pro) is a multifunctional viral protein involved in vection and movement of potyvirus; suppression of host post-transcriptional gene silencing reaction; and synergism of potyvirus with other viruses, notably potexvirus. When the HC-Pro of plum pox potyvirus (PPV) was transiently expressed in N. benthamiana and N. clevelandii plants via potato virus X (PVX) vector, a highly...
