Abstract
To analyze the role of the 2b protein 2bP of Peanut stunt virus PSV in the viral infection cycle we constructed PSV mutants that express either no 2bP or Nterminaltruncated 2bP The accumulation of wildtype and mutant viruses in tobacco protoplasts indicated that the 2b cistron is not essential for viral replication Viral accumulation in Nicotiana benthamiana plants suggested that the 2b cistron is responsible for viral accumulation in inoculated and upper leaves and has a role in virulence The involvement of eight Nterminal amino acids of 2bP in these functions is discussed
