Interaction of Lucerne Transient Streak Virus and the Viroid-like RNA-2 of Solanum nodiflorum Mottle Virus Jones, A. T. and Mayo, M. A.,, 64, 1771-1774 (1983), doi = https://doi.org/10.1099/0022-1317-64-8-1771, publicationName = Microbiology Society, issn = 0022-1317, abstract= SUMMARY The particles of two serologically unrelated viruses, Solanum nodiflorum mottle (SNMV) and lucerne transient streak (LTSV), contain linear single-stranded RNA-1 (mol. wt. approx. 1.4 × 106), and linear and circular RNA molecules of mol. wt. approx. 1.2 × 105 (RNA-2). SNMV RNA-2 is reported to be part of the virus genome, but LTSV RNA-2 is a satellite-like RNA which is not necessary for the replication of LTSV RNA-1 or for the production of virus particles. When inoculated alone, SNMV RNA-2 did not infect plants but when inoculated with LTSV RNA-1 it replicated, modified the symptoms induced by LTSV and was packaged in particles with the serological specificity of LTSV. Thus, SNMV RNA-2 behaves like a satellite RNA in its interactions with LTSV. LTSV cultures containing LTSV RNA-2 or SNMV RNA-2, or lacking RNA-2, were distinguishable by reactions in some plant species but their particles were indistinguishable serologically, in sedimentation rate and in buoyant density in CsCl., language=, type=
