Small Linear Satellite RNAs

Research output: Chapter in Book/Report/Conference proceedingChapter


Plant virus satellites are molecular parasites of plant viruses. The most common plant virus satellites are the small linear satellite RNAs (satRNAs). The satRNAs rely on a helper virus for replication and encapsidation/dissemination, but do not supply any essential function to the helper virus. They do not encode any functional proteins, and appear to be highly structured. They can affect the titer of the helper virus and alter the host symptoms induced by the helper virus. Studies of satRNAs have been aimed at understanding virus replication, RNA structure, pathogenicity, and evolutionary mechanisms. This chapter is an overview of small linear satRNAs and focuses on replication and interactions with helper viruses.
