The nucleotide sequences of citrus bent leaf viroid (CBLVd) (formerly designated CV-Ib) and citrus exocortis viroid (CEVd), both found amongthe citrus viroid (CVd) populations from five graft-transmissible dwarfing complexes (GTDCs) originating from different source plants and geographical locations in Israel, were determined. The sequence homologyvaried only slightly among the CBLVd sequence variants, i.e., 0-7 nucleotides (nts); originating from a single GTDC and 2-8 nts between CBLVds that were otained from different GTDCs. The lowest level of homology between CBLVd variants obtained from citrus was 97.5%. Considerably larger variation (8-15 nucleotide changes) was observed between CBLVd variants derived from citrus and the type strain differed from all variants in six positions, located at 38, 62, 138, 179, 264, and 268 nts. |
