Wandel durch Diversity Managementucleic acids which have properties similar to those of the causal agent of potato spindle tuber disease (Diener, 1971.). Presently known viroids consist solely of a low molecular weight RNA of about 75,000–130,000. Introduction of this RNA into susceptible hosts leads to autonomous replication of the RNA, and, in some hosts, to disease.
