Figure 4. — Distribution of PWISs between full-length sequence variants of viroids not classified yet of viroids currently classified in the genera Apscaviroid, Coleviroid and Pospiviroid of family Pospiviroidae, and in the genus Pelamoviroid of family Avsunviroidae. The TIS proposed as a species demarcation criterion for each genus is indicated below the graphic and marked by a broken, red, vertical line. The maximum PWIS between variants of each unclassified viroid is marked by a vertical line of different color for each viroid, with the numerical value (identity %) indicated below.
