A single nucleotide substitution converts potato spindle tuber viroid (PSTVd) from a noninfectious to an infectious RNA for nicotiana tabacum.

Virology - 15 Dec 1996

Abstract excerpt

Mechanical inoculation of Nicotiana tabacum with the PSTVd isolate KF 440-2 from the host plant tomato resulted in the de novo emergence, replication, and accumulation of a new "tobacco variant," designated PSTVd NT. It produces no symptoms in tobacco but, like PSTV KF 440-2, severe ones in tomat...
