Viroid Replication Mechanisms

  • Conference paper
Recognition and Response in Plant-Virus Interactions

Part of the book series: NATO ASI Series ((ASIH,volume 41))

Abstract

Viroids are pathogens which are the causal agents of some diseases of higher plants. At the molecular level, viroids consist only of a single-stranded, circular RNA molecule of 246–375 nucleotides. The autonomous replication of viroid RNA in the infected cell requires a close interaction with host factors. At least two replication mechanisms for different viroids can be envisaged. This chapter gives a brief review of possible mechanisms of viroid replication, summarizing our present knowledge of the synthesis of viroid RNA, the processing reactions which form the mature circular RNA molecule, and the relationships between viroid structure and replicability.
