Abstract:	Properties of a strain of tobacco mosaic tobamovirus (TMV-S) originally isolated from soyabean were compared with those of 2 isolates of the common strain TMV (American Type Culture Collection; Rockville, MD (ATCC) PV135 and PV-220), one TMV strain infecting Phaseolus vulgaris [sunn-hemp mosaic tobamovirus] (TMV-B, ATCC PV-742), and sunnhemp mosaic tobamovirus (SHMV, ATCC PV-744). The virion capsid proteins subunits of the common and soyabean strains were 21 kDa. Reduced and alkylated capsid proteins of TMV-B and SHMV migrated as 2 bands and more rapidly than capsid proteins of the common and soyabean strains during SDS-PAGE. Host symptomatology, serological assays, particle morphology and gel electrophoresis of the monopartite genome (6.4 kb) and whole virions demonstrated that TMV-S was closely related to the common strain of TMV but only distantly related to SHMV and TMV-B, which should be regarded as an SHMV isolate.
