Research Abstract |
Orchid fleck virus(OFV), a unique two-segmented negative-sense RNA virus, induces an intranuclear electron-lucent viroplasm(inclusion) in infected plant cells. We studied the molecular mechanism by which OFV viroplasms are produced in vivo. Transiently expression examinations by Agrobacterium-infiltration reveled that coexpression of nucleocapsid protein N and the putative phosphoprotein P, in the absence of virus infection, was sufficient for the formation of an intranuclear electron-lucent viroplasm-like structure in Nicotiana benthamiana cells.
