As with other biological entities, viroid-like RNAs form groups of related sequences, which most likely originate from a relatively recent common ancestor. The clusters below, and their derived information, are the results of a custom, automatic pipeline we wrote to consistently process all sequences. Note that these clusters are not necessarily representative of the refined taxonomy of the sequences they contain but are instead optimized to make it easier to examine groups of (potentially) related sequences. To browse sequences based on their taxonomic classification, use the search page.
Viroid species demarcation historically used 90% as a cutoff.
