Notes on Genus: Avsunviroid
Type member: Avocado sunblotch viroid
This is one of three genera of viroids assigned to the family Avsunviroidae
. All members of this family lack a central conserved region (CCR) and have the ability to self-cleave through hammerhead structures. This genus differs from other viroids in the family because its members have a rod-like structure, low (38%) G+C content and thermodynamically unstable hammerhead ribozymes.
Like all viroids, they have no virions and encode no proteins.
One circular, single stranded molecule of RNA, 247-251 nucleotides long.
Genus Genomic Organization
The RNA is non-coding.
