title: A novel aspect of the information content of viroids.
abstract: Viroids were found to exhibit a structural periodicity characterized by repeat units of a length of 11 or 12 (potato spindle tuber viroid group and coconut cadang-cadang viroid), 60 (apple scar skin viroid) and 80 (avocado sunblotch viroid) nucleotide residues, respectively. It is suggested that structural periodicity of viroids is an indication of their protein-binding ability.
