Analysis of Viroid Pathogenicity by Genome Modification
Viroids are the smallest autonomously replicating pathogenic agents yet described.1 Viroids are low molecular weight RNAs (1.1–1.3 × 105) that can be isolated from certain species of plants afflicted with specific diseases. Although viroids have been discovered because they cause symptoms in some hosts, they are often replicated in other hosts without causing obvious damage.
