Experimental characterization of zeta viruses and discovery of betaviroid-like RNAs expand the diversity of coding circular RNA replicons
Viroid-like RNAs (vdlRNAs) are infectious agents characterized by single-stranded circular genomes folding into compact secondary structures, often containing self-cleaving ribozymes involved in replication. Recent metatranscriptomic studies have expanded their diversity across multiple ecological niches and revealed n...
