Interpretive Summary: Citrus exocortis disease was first described in 1948 by a bark scaling disorder on trifoliate orange rootstocks. The causal agent of citrus exocortis is a viroid, citrus exocortis viroid (CEVd). Indexing studies have shown that many "old lline" citrus cultivars are infected with several viroids, not all of which are associated with known disease(s). This summary of the basic characteristics of citrus exocortis disease and molecular properties of the several viroids infecting citrus was prepared for the Encyclopedia of Plant Pathology, a comprehensive and authoritative compendium of the many terms, concepts, and principles embodied in the broad science of plant pathology. These volumes will cover all aspects of plant pathology, including causes, development, diagnosis, and control of plant disease. They will be used primarily by those active in plant disease research and teaching. Students, consultants, gardeners, and other non-plant pathologists will find it a definitive and comprehensive source of information on plant diseases.
