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 N-terminal-truncated 2bP. The accumulation of wild-type 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 N-terminal amino acids of 2bP in these functions is discussed.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
