Potential biological control of potato spindle tuber viroid
A first report on biological control of potato spindle tuber viroid is based on a virus/satellite-viroid interaction.
Lycopersicon esculentum preinoculated with the total RNA from cucumber mosaic cucumovirus strain S and 8 or 16 days later with a severe strain of PSTV showed only mild disease symptoms in contrast to plants inoculated with PSTV only. Serological tests also showed a reduced level of viroid RNA in plants which were preinoculated with the RNA of CMV strain S.
