Notes on Genus: Cocadviroid
Type member: Coconut cadang-cadang viroid
This is one of five genera of viroids assigned to the family Pospiviroidae
. Like all the other genera in this family, members have a central conserved region (CCR) and lack the ability to self-cleave through hammerhead structures. Classification is based on the sequence of the CCR. An arbitrary level of 90% sequence similarity currently separates variants from species.
Like all viroids, they have no virions and encode no proteins.
One circular, single stranded molecule of RNA, 245-285 nucleotides long.
Genus Genomic Organization
