Characterization of Potato spindle tuber viroid (PSTVd) incidence and new variants from ornamentals

Date: 25.9.2015 

We analyzed the spreading and persistence of PSTVd variants in several ornamentals in the territory of the Czech Republic. The pool of PSTVd variants detected in Solanum jasminoides, S. muricatum, Datura sp. and Brugmansia sp. was biolistically transferred to Matricaria chamomilla, Argyranthemum frutescens and Diascia sp., species which we found as sensitive hosts for PSTVd from ornamentals. The PSTVd pool showed sequence changes and increased variation after its transfer to potato, suggesting a wide adaptation potential of PSTVd in this crop. Potato exhibited genotype-dependent leaf and spindle tuber symptoms, when inoculated with the sap from S. jasminoides infected with the predominant and sequence-stable PSTVd-S1.
