  • Title: Virus-associated small satellite RNAs and viroids display similarities in their replication strategies.
    Author: Rao AL, Kalantidis K.
    Journal: Virology; 2015 May; 479-480():627-36. PubMed ID: 25731957.
    Abstract:
    Since the discovery of non-coding, small, highly structured, satellite RNAs (satRNAs) and viroids as subviral pathogens of plants , have been of great interest to molecular biologists as possible living fossils of pre-cellular evolution in an RNA world. Despite extensive studies performed in the last four decades, there is still mystery surrounding the origin and evolutionary relationship between these subviral pathogens. Recent technical advances revealed some commonly shared replication features between these two subviral pathogens. In this review, we discuss our current perception of replication and evolutionary origin of these petite RNA pathogens.
