Abstract:
Isolated RNA genomic segments (RNAs 1, 2, and 3) of tomato aspermy virus and of three strains of cucumber mosaic virus (CMV) were inoculated to leaves of Chenopodium amaranticolor Costs and Reyn in all combinations. The data presented demonstrate that whereas RNA 3 is readily interchangeable between the two viruses to produce infections resulting in lesion development, RNAs 1 and 2 are not, although they are interchangeable between the three CMV strains. The possible significance of these observations to virus taxonomy is discussed.
