Phenotypic responses of soybean L800 (Rsv1) to mechanical inoculation with progeny derived from the infectious cDNA clones of Soybean mosaic virus (SMV) strains N (SMV‐N), G7 (SMV‐G7) and G7d (SMV‐G7d). Sap containing progeny of the viruses from biolistically inoculated Williams82 served as the inoculum. The inoculated plants were photographed 14 days post‐inoculation. It should be noted that plants inoculated with SMV‐N are functionally immune, do not exhibit any symptoms and the virus cannot be recovered from the inoculated plants. In contrast, L800 (Rsv1) inoculated with SMV‐G7 and SMV‐G7d is symptomatic. SMV‐G7 induces stunting and systemic necrosis visible on the first trifoliate leaf. In contrast, SMV‐G7d causes a systemic mosaic pattern.
