“…Microscopy of ultrathin sections of both plant cells and insect cells infected with RBSDV revealed viroplasm, virus crystals and tubular structures (Shikata, 1969 ;Shikata & Kitagawa, 1977). The same structures are observed in MRDV-infected plants and insects (Gerola & Bassi, 1966 ;Vidano, 1970) and in oat sterile dwarf fijivirusinfected plants (Milne, 1980). In this study, RBSDV S9 was found to have two nonoverlapping ORFs (ORF1 and ORF2) transcribed as a single piece of mRNA, as is the case in RBSDV S7.…”

The proteins encoded by rice black streaked dwarf fijivirus (RBSDV) genomic segments 7-10 (S7-S10) were characterized. Open reading frames (ORFs) from these segments were expressed as fusion proteins in Escherichia coli. Antibodies raised against the expressed products were used as probes to determine whether the viral ORFs encode structural proteins. In Western blots, antibodies to the expressed S8 and S10 products reacted with a core capsid (65 kDa) and a major outer capsid (56 kDa) protein, respectively, while none of the antibodies to S7 and S9 products reacted with structural

The significance of these protrusions is, however, not known.…”

“…These and some other enation diseases have recently been found associated with dense accumulations of such spherical or polyhedral viruses, e.g. wound tumour (Shikata et al, 1964), maize rough dwarf (Gerola and Bassi, 1966) and sugar-cane Fiji disease (Gianotti et al, 1968). Therefore, the group of virus diseases characterized by histoid tissue outgrowths as brought together by Bos and Grancini (1968) seems heterogeneous in epidemiology (type of vectors) as well as in etiology.…”

“…If so then the virus differs basically from those of wound tumour and of maize rough dwarf. Particles of the latter diseases are polyhedral and 60 m~z in diameter for wound tumour (Bils and Hall, 1962) and 50-70 mix for maize rough dwarf (Gerola and Bassi, 1966). These and some other enation diseases have recently been found associated with dense accumulations of such spherical or polyhedral viruses, e.g.…”

In ultrathin sections of tumorous tissues of white clover plants artificially infected by grafting with the clover enation virus nuclei and nucleoli were very much enlarged. Such nuclei contained massive amounts of tubular particles in crystalline array. In spaces between the nuclear membrane lamellae such particles had an additional coat and usually occurred in irregular accumulations. These bacilliform particles measured about 200 • 80 m~z. This virus was not found in normal tissues.Two other viruses with elongated particles of 475 and 665 m~ were also observed in non-neoplastic tissues. They were easily detected in negatively stained chop preparations, rapidly transmitted by sap, and considered to be mere contaminants.Enation virus diseases are heterogeneous in epidemiology and etiology. Several have recently been found associated with dense accumulations of big spherical or polyhedral virus particles. The virus detected here closely resembles several bacilliform viruses described in recent years. These viruses are quite different in symptomatology and epidemiology.
