The sequence analysis of PSTVd NT revealed a single nucleotide substitution from C-->U at position 259, which might be involved in protein binding and in viroid processing in both tobacco and tomato.
An infectious viroid RNA replicon evolved from an in vitro‐generated non‐infectious viroid deletion mutant via a complementary deletion in vivo.

This is the first report that the deletion‐abolished infectivity of a viroid is restored by an additional deletion that concurrently restabilized its perturbed secondary structure by abandoning an internal segment of the rod‐like molecule.
