Variants of Coconut cadang-cadang viroid isolated from an African oil palm (Elaies guineensis Jacq.) in Malaysia.
Variants of Coconut cadang-cadang viroid have been identified in a plantation oil palm growing in Malaysia. Three size classes are described, comprising 297, 293, and 270 nt. Compared with the 296-nt form of coconut cadang-cadang viroid (CCCVd), all variants substituted C31 --> U in the pathogenicity domain and A175 --> C in the right-hand terminus. Other mutations and deletions accounted for the different sizes. These are the first sequences reported for variants of Coconut cadang-cadang viroid in a species other than coconut palm, and this is the first evidence that variants closely related to CCCVd occur outside the Philippines.
