title: A 1.5 kb sequence homology in 3'-terminal regions of RNA-1 and RNA-2 of a birch isolate of cherry leaf roll nepovirus is also present, in part, in a rhubarb isolate.
abstract: A series of cDNA clones has been made from the birch isolate of cherry leaf roll nepovirus. Restriction enzyme analysis and sequencing showed that at the 3' end, RNA-1 and RNA-2 are identical for 1.5 kb. Also a 0.7 kb 3' end homology exists between the birch and rhubarb isolate. These sequences do not seem to code for any proteins; however, the sequence conservation points to a role in virus replication.
