Transencapsidation of the Rice gall dwarf virus (RGDV) inner core by the Rice dwarf virus (RDV) outer capsid P8 protein was examined in vitro and in planta. When RGDV core particles were incubated with an extract
from RDV P8-transgenic rice leaf tissue, RDV P8 encapsidated the RGDV core particles to form double-shelled virus-like particles
in vitro. In contrast, when RDV P8-transgenic rice plants were inoculated with RGDV, progeny RGDV particles contained RGDV
P8 but RDV P8 was not detectable in the virions. No significant differences were found in acquisition by the vector insects
and subsequent transmission rates between RGDV infecting nontransgenic rice plants and those infecting RDV P8-transgenic rice
plants. These results indicate that mechanisms of and/or requirements for interactions between P8 and the inner core particles
of phytoreoviruses differ between in vitro and in planta. 相似文献
