Plant rhabdoviruses replicate and assembly in nuclei, cytoplasm, and viroplasms. They can be div ided into three subgroups based on the site of nucleocapsid formation and the assembly of virions. Viruses form their nucleocapsids in the nucleus, mature through the nuclear membrane, and accumulate in the perinuclear spaces. Sonchus yellow net virus, potato yellow dwarf virus. Lettuce necrotic yellow virus.
Viruses form nucleocapsid, mature in a special membrane-bound granular structure called viroplasm.
After viruses bud from membranes associated with the viroplasm, they accumulates in a vacuole-like structure. Barley yellow striate mosaic virus . References Bertaccini, A., and Bellardi, M. G. 1992.
