title: Assembly of single-shelled cores and double-shelled virus-like particles after baculovirus expression of major structural proteins P3, P7 and P8 of Rice dwarf virus.
abstract: Expression of the core capsid protein P3 of Rice dwarf virus in a baculovirus system resulted in the formation of single-shelled core-like particles in insect cells in the absence of any other capsid proteins. Double-shelled virus-like particles were also observed upon mixing or co-expression of P3 and the major outer capsid protein P8, suggesting that P3 and P8 have the ability to form double-shelled particles both in vivo and in vitro. Core protein P7 expressed in a similar manner was incorporated into the virus-like particles.
