“…A host range comparison between these three isolates was conducted using mechanical inoculation onto indicator plants; all three had an identical host range. Although related serologically, the virus from Nemesia displayed a host range quite different from that reported for the type isolate of ScrMV, isolated from Scrophularia nodosa (Hein, 1959;Bercks et al ., 1971;Bercks, 1973). Koenig & Lesemann (2000) reported that a similar virus isolated from Nemesia and Diascia was not ScrMV but a distinct tymovirus, for which the name Nemesia ring necrosis virus (NeRNV) is proposed.…”

“…The tymoviruses known to infect legumes are: Desmodium yellow mottle virus (Walters and Scott 1972), Plantago mottle virus (Granett 1973), okra mosaic virus (Givord and Hirth 1973), Ononis yellow mosaic virus (Gibbs et al 1966), Scrophularia mottle virus (Hein 1959) and Clitoria yellow vein virus (K. Bock, personal communication). KYMV can be distinguished from these viruses, except Clitoria yellow vein virus, using a limited number of experimental hosts (Table 3).…”

A virus has been isolated from an Australian native legume, Kennedya rubicunda. The virus, which we call Kennedya yellow mosaic virus (KYMV), is sap-transmissible to a limited number of other plant species. Purified preparations of KYMV particles contain two types of rounded isometric particles 28 nm in diameter. Particles of one type are infectious nucleoprotein with a sedimentation coefficient of 110 S and particles of the other type are non-infections protein shells with a sedimentation coefficient of 54 S. Nucleoprotein particles of KYMV contain 34 % single-stranded ribonucleic acid with a molar base content of guanine 15 %, adenine 22 %, cytosine 37 %, and uracil 25 %. The present cryptogram of KYMV is Ril : */34 : SIS: S/*.

“…Our virus for which in a preliminary account (RANA et al 1984) we suggested the name Anagyris vein yellowing virus should be named Anagyris strain of ScrMV. The Anagyris strain as well as OYMV and PIMV have been isolated from naturally infected leguminous hosts, ScrMV can at least experimentally be transmitted to hosts in this family (HEIN 1959).…”

A virus isolated from Anagyris foetida and infecting species in the Leguminosae and Solanaceae had typical properties of a tymovirus. It sedimented as two components (49 S and 103 S) and induced the formation of double membrane‐bounded invaginations in the chloroplasts of infected cells. Large numbers of ‘empty shells’ were found in the nuclei. The coat protein had a molecular weight of c. 20.000 and the RNA consisted of c. 5500 nucleotides. Crystallization of the virus in laminal crystals could be achieved by precipitation with 10 % polyethylenglycol 6000 and 1 % NaCl. Serologically, the virus was closely related to Scrophularia mottle, Ononis yellow mosaic and Plantago mottle viruses. The four viruses which all infect leguminous hosts are separated by serological differentiation indices which are mostly between 1 and 3. It is therefore suggested that they all should be considered as strains of the same virus which for reasons of priority should have the name Scrophularia mottle virus (ScrMV). The proposed Anagyris strain clearly differs from the Scrophularia mottle, Ononis yellow mosaic and Plantago mottle strains of ScrMV in host range, symptomatology, electrophoretic mobility serological properties and some cytopathogenic effects. It is not clear why the Anagyris strain infects A. foetida systemically in nature, but only locally under greenhouse conditions.
