The nucleotide sequence (5669 residues) of the genomic RNA of cucurbit
aphid-borne yellows luteovirus (CABYV) is presented. Analysis of geno
me organization and sequence homologies indicate that CABYV is a membe
r of luteovirus Subgroup 2 (other sequenced members: beet western yell
ows virus, potato leafroll virus, and barley yellow dwarf virus, RPV i
solate) and appears to be most closely related to beet western yellows
virus. (C) 1994 Academic Press, Inc.
