Self-cleavage of virusoid RNA is performed by the proposed 55-nucleotide active site.
Forster AC, Symons RH. Forster AC, et al. Cell. 1987 Jul 3;50(1):9-16. doi: 10.1016/0092-8674(87)90657-x. Cell. 1987. PMID: 3594567
Virusoids are circular single-stranded RNAs dependent on plant viruses for replication and encapsidation. Recently, we showed that an in vitro-synthesized RNA containing 273 nucleotides of the 324-nucleotide virusoid of lucerne transient streak virus self-cleaves at …

Self-cleavage of plus and minus RNAs of a virusoid and a structural model for the active sites.
Forster AC, Symons RH. Forster AC, et al. Cell. 1987 Apr 24;49(2):211-20. doi: 10.1016/0092-8674(87)90562-9. Cell. 1987. PMID: 2436805
Virusoids are circular single-stranded RNAs dependent on plant viruses for replication and encapsidation. Virusoid replication appears to involve longer-than-unit-length plus and minus RNAs, indicating that unit-length plus RNA is generated by specific cleavage reac …

Is hammerhead self-cleavage involved in the replication of a virusoid in vivo?
Sheldon CC, Symons RH. Sheldon CC, et al. Virology. 1993 Jun;194(2):463-74. doi: 10.1006/viro.1993.1285. Virology. 1993. PMID: 7684871
As was predicted if hammerhead self-cleavage is involved in in vivo cleavage of (-) RNAs, high molecular weight (-) vLTSV RNAs were present in total RNA extracts from these mutant inoculated plants, but not in wild-type inoculated plants. Surprisingly however, the mutated viru …

A replication cycle for viroids and other small infectious RNA's.
Branch AD, Robertson HD. Branch AD, et al. Science. 1984 Feb 3;223(4635):450-5. doi: 10.1126/science.6197756. Science. 1984. PMID: 6197756 Review.
Many features of this pathway, which involves multimeric strands of both polarities, may be shared by other small infectious RNA's including certain satellite RNA's and "virusoid" RNA's which replicate in conjunction with conventional plant viruses. ...

Sequence diversity of hepatitis D virus in Mongolia.
Magvan B, Kloeble AA, Ptok J, Hoffmann D, Habermann D, Gantumur A, Paluschinski M, Enebish G, Balz V, Fischer JC, Chimeddorj B, Walker A, Timm J. Magvan B, et al. Front Med (Lausanne). 2023 Mar 13;10:1108543. doi: 10.3389/fmed.2023.1108543. eCollection 2023. Front Med (Lausanne). 2023. PMID: 37035318 Free PMC article.
INTRODUCTION: The Hepatitis Delta Virus (HDV) is a defective, single-stranded RNA virusoid encoding for a single protein, the Hepatitis Delta Antigen (HDAg), which requires the hepatitis B virus (HBV) envelope protein (HBsAg) for its transmission. ...

Long Noncoding RNAs in Plant Viroids and Viruses: A Review.
Shrestha N, Bujarski JJ. Shrestha N, et al. Pathogens. 2020 Sep 18;9(9):765. doi: 10.3390/pathogens9090765. Pathogens. 2020. PMID: 32961969 Free PMC article. Review.
Yet the satellite RNAs are single-stranded and include either large linear protein-coding ss RNAs, small linear ss RNAs, or small circular ss RNAs (virusoids). The satellite RNAs lack sequence homology to the helper virus, but unlike viroids need a helper virus to replicat …

Possible evolutionary origin of primitive protein-encoding mRNAs as a virusoid-like ribo-organism.
Ohnishi K. Ohnishi K. Nucleic Acids Symp Ser. 1990;(22):39-40. Nucleic Acids Symp Ser. 1990. PMID: 1714569
E. coli rnpA and rpmH genes encoding the protein portion of ribonuclease (RNase) P and L34 ribosomal protein were found to be homologous to the entire sequence of M1 RNA and virusoids. The resulting alignment strongly suggests that most primitive mRNAs must have emerged fr …
