Molecular characterization of Potato spindle tuber viroid in dahlia

A new variant of Potato spindle tuber viroid (PSTVd) was detected for the first time from dahlia grown in Japan. The dahlia isolate of PSTVd formed a quasi-species and a major sequence variant consisting of 361 nucleotides in length, including five substitutions, three insertions, and one deletion, when compared to the intermediate strain from potato. In bioassays with the new isolate, Rutgers tomato developed mild stunting and leaf curling.
