Structure, Cellular Location, and Cytopathology of Viroids

  • Chapter
Electron Microscopy of Plant Pathogens

Abstract

Viroids are plant pathogens distinguished from viruses by the absence of a protein coat and by their small size. They are circular, single-stranded RNA molecules consisting of a few hundred nucleotides, the smallest having about 240 and the largest about 600 nucleotides. Since viroids can have only a very limited coding capacity and as there is no experimental evidence for a viroid-coded translation product, one has to assume that viroid replication and pathogenesis depend completely on the enzyme systems of the host (for reviews see [1–5]).
