“…LTSV) for replication (Tien-Po et aL, 1981;. Viroid-like sat-RNAs have also been reported in a few other sobemoviruses, namely velvet tobacco mottle virus (VTMoV; Randles et al, 1981;Francki et aL, 1986), Solanum nodiflorum mottle virus (SNMV; Jones & Mayo, 1984) and subterranean clover mottle virus (SCMoV; Francki et al, 1983a). Most sobemoviruses including cocksfoot mottle virus (CfMV), turnip rosette virus (TRosV), southern bean mosaic virus (SBMV) and sowbane mosaic virus (SoMV), however, are normally devoid of sat-RNAs (reviewed by Hull, 1988).…”
