Solution:

In 1971, T.O. Diener discovered a new infectious agent called viroids that was smaller than viruses and caused potato spindle tuber disease. Viroids are the smallest pathogen and cause diseases only in plants. Viroids are naked RNA molecules that are not enclosed by a protein capsid, they are made up of 249 to 399 nucleotides only.
