“…NVMV is not included with the furoviruses (Brown, 1989) but has been included with the fungus-transmitted and similar labile rod-shaped viruses by Brunt & Shikata (1986). These viruses are serologically distinct from each other.…”

“…Particle morphology (a helical capsid of 2.9 nm pitch, diameter of 18 nm) and coat protein Mr value 21400 (Randles et al, 1976) could place NVMV in either the tobamo-, hordei-, tobravirus (Matthews, 1982), or furovirus (fungus-transmitted labile rod-shaped viruses with a bipartite genome; Brunt & Shikata, 1986; 0000-9385 © 1990 SGM Richards, 1989;Brown, 1989) groups. However, no serological relationship to tobacco mosaic tobamovirus (TMV), beet necrotic yellow vein (BNYVV), soil-borne wheat mosaic (SBWMV), or potato mop top furoviruses, barley stripe mosaic hordeivirus (BSMV) or tobacco rattle tobravirus has been detected (Randles et al, 1976).…”

DNA complementary to Nicotiana velutina mosaic virus (NVMV) RNA was 0oned and five segments larger than 0.9 kb were ~used in Northern blot hybridization analysis to identify two virus-specific RNAs, approximately 8 kb (RNA l) and 3 kb (RNA 2) in size. The clones selected as probes did not hybridize with RNA from various tobamoviruses, or from beet necrotic yellow vein (BNYVV) and peanut clump furoviruses. In an attempt to determine the taxonomic position of the virus, about 75 % of the NVMV RNA 2 was sequenced and four open reading frames (ORFs) were identified. ORFs 1, 2 and 3 encode proteins of Mr 20K, 39K and 13K, whereas ORF 4 was incomplete. ORFs 2, 3 and 4 overlapped in an arrangement closely resembling the triple gene block identified in BNYVV RNA 2, barley stripe mosaic virus (BSMV) RNA 2, potato virus X and potato virus M RNA. The presumed coat protein gene ofNVMV RNA 2 (ORF l) is situated to the 5' side of the triple gene block as for BNYVV and BSMV RNA 2. Amino acid homologies were detected among the 13K and 14K proteins of NVMV RNA 2, BNYVV RNA 2 and BSMV RNA 2. Significant homology was also detected between the 39K protein of NVMV RNA 2 and the 42K protein of BNYVV RNA 2, with a motif specific for ATP-and GTPbinding (NTP-binding motif), and a conserved viral DNA polymerase domain. The presence of a triple gene block in NVMV RNA 2 indicates that NVMV has affinities with members of the hordei-, furo-, potexand carlavirus groups but not with the tobamovirus group. The divided RNA genome of NVMV, and the sizes of the two RNAs suggest that NVMV is most closely allied to the furoviruses, but the unique nature of its different biological properties and lack of any serological relationships with furoviruses lead us to conclude that NVMV has no clear relatedness to any taxonomic group of plant viruses.

“…It can be transmitted mechanically and has been purified and an antiserum prepared (Adams et al, 1988b). It has particles predominantly of two lengths (1 50 and 300 nm) and is a member of the furovirus group (Brunt & Shikata, 1987). Using the F(ab)2 ELISA method, as described above for BaYMV, a serological relationship with wheat soil-borne mosaic furovirus, but not with some other furoviruses, could be demonstrated (Table 4).…”

Fungally‐transmitted viruses of cereals in the UK¹

The distribution of two UK strains of barley yellow mosaic virus has been studied and both have been transmitted experimentally by Polymyxa graminis. cDNA hybridization studies support the suggestion that the strains should be considered distinct viruses. Oat mosaic and oat golden stripe (OGSV) viruses also occur in the UK. OGSV is a furovirus related to wheat soil‐borne mosaic furovirus: it has particles of two lengths and a bipartite genome.

“…The natural occurrence, virus-vector relationships, control and molecular biology of furoviruses have recently been reviewed thoroughly (Adams, 1988;Brunt, 1988;Brunt & Shikata, 1986;Brunt & Richards, 1989;Bouzoubaa et al, 1988;Jones, 1988;Putz et ul., 1988;Schlosser, 1988;Solomon & Wastie, 1988 …”

Viruses and virus‐like pathogens transmitted by zoosporic fungi¹

The viruses and virus‐like pathogens transmitted by zoosporic fungi are reviewed. The nine furoviruses (and possible members of the group), with labile rod‐shaped particles, have nearly all been shown to be transmitted by plasmodiophoromycete vectors. As they have been reviewed extensively elsewhere, they are covered only briefly; important examples are beet necrotic yellow vein furovirus and potato mop‐top furovirus. Five viruses with filamentous particles, tentatively recognized as poty viruses, are transmitted by Polymyxa graminis. Within this group, wheat yellow mosaic virus should be considered to include wheat spindle streak mosaic virus, while the M and NM forms of barley yellow mosaic virus, the best known members of the group, should probably be regarded as distinct viruses. Chytrids (especially Olpidium brassicae) transmit a variety of viruses in different groups (e.g. tobacco necrosis necrovirus, lettuce big‐vein virus, melon necrotic spot carmovirus, red clover necrotic mosaic dianthovirus). Finally, several diseases caused by uncharacterized pathogens appear to be transmitted by O. brassicae: freesia leaf necrosis, lettuce ring necrosis, pepper yellow vein, watercress chlorotic leaf spot.
