3'-terminal sequence of the plum pox virus PS and ŏ6 isolates: evidence for RNA recombination within the potyvirus group.
The sequence of the 3'-terminal 1768 nucleotides of the PS and ŏ6 isolates of plum pox virus (PPV) has been determined and compared with that of the equivalent regions of other PPV isolates sequencedExpand

Identification of a pathogenicity determinant of Plum pox virus in the sequence encoding the C-terminal region of protein P3+6K(1).
A full-length genomic cDNA clone of a plum pox potyvirus (PPV) isolate belonging to the M strain (PPV-PS) has been cloned downstream from a bacteriophage T7 polymerase promoter and sequenced.Expand

Processing of the plum pox virus polyprotein at the P3-6K1 junction is not required for virus viability.
Proteolytic processing of the potyvirus polyprotein is mainly performed by the virus-encoded NIa protease, whose cleavage sites are characterized by conserved heptapeptide sequences. PartialExpand

Proteolytic processing of the plum pox potyvirus polyprotein by the NIa protease at a novel cleavage site.
The expression of potyvirus genomic RNA takes place through translation of its unique long and functional open reading frame into a large polyprotein that undergoes extensive proteolytic processing.Expand

Properties of the active plum pox potyvirus RNA polymerase complex in defined glycerol gradient fractions.
As a first step in the study of the replication of plum pox virus (PPV) RNA, an in vitro virus-specific RNA polymerase activity was characterized in a crude membrane extract (Martin and Garcia,Expand

Mutational analysis of plum pox potyvirus polyprotein processing by the NIa protease in Escherichia coli.
A binary Escherichia coli expression system has been used to study the pathway for proteolytic processing of the plum pox potyvirus (PPV) polyprotein. Trans cleavage at the carboxyl end of theExpand
