“…sat-RNA, but rather to be due to a preference for a particular sat-RNA. In a study with the Y sat-RNA, one sat-RNA variant, which was apparently a low-level contaminant, was also shown to be preferentially amplified over another, upon repeated passage (Nakashima and Ehara 1989). These results contrast with a recent study in…”

Satellite RNAs (sat-RNAs) are small molecular parasites associated with a number of plant RNA viruses. The cucumber mosaic virus (CMV) sat-RNAs are ca. 335 nucleotides and have evolved to produce a large number of closely related sat-RNAs. Different cucumoviruses can act as helper viruses in the amplification of CMV sat-RNAs. We have found that different helper viruses show a preference for a particular sat-RNA in a mixed infection. In this study the specificity of WL47 sat-RNA amplification by LS-CMV and of D4 sat-RNA amplification by tomato aspermy virus in mixed infections was examined. Recombinant cDNA clones of D4 sat-RNA and WL47 sat-RNA were used to map the sat-RNA sequences responsible for the helper virus selection of a specific sat-RNA for amplification.

“…However, the satellite sequences could exist in the plant genome in fragments, which, under appropriate conditions are brought together. Although many laboratories have reported the "spontaneous" appearance of satellites in experimental plants (25,51,57,99,115,123,147,155,157,164,183,195,197), most of these could be accounted for either by very low levels of satellites already existing in virus isolates, which are amplified under the appropriate conditions (i.e., experimental conditions), or by contamination of experimental plants with satellite. In one study of CMV satellite RNAs, the satellite RNA molecules were shown to be stable on tobacco plants for 25 days in the absence of helper virus (88).…”
