A 1.5KB 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

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.
