Since their initial identification nearly four decades ago, fundamental analyses of pathogenic and interdependent interactions involving these agents have contributed enormously to our appreciation of

Satellite Tobacco Mosaic Virus,icate, they need to be a dependent partner in a mixed infection with another virus, usually referred to as the helper virus. The helper virus is presumed to supply the replicase function the satellite virus lacks, but it is not needed for particle formation, since the satellite virus codes for its own capsid protein.

Structure and Functional Relationships of Satellite RNAs of Cucumber Mosaic Virus, 1988), as well as in Japan (. et al. 1989) and Spain (. et al. 1992), led to the unequivocal establishment of CMV strains containing necrogenic satellite RNAs as the causal agents of tomato necrosis.
