The complete nucleotide sequence of Olive latent ringspot virus (OLRSV) RNA
-2 was determined. This RNA is 3969 nucleotides in length and contains a si
ngle open reading frame of 3448 nt, that encodes a polypeptide of 1146 amin
o acids, with a calculated M-r of 126,044. OLRSV RNA-2 has a structural org
anization typical of nepoviruses, with the coat protein (CP) cistron locate
d in the C-terminal and the putative movement protein (MP) in the N-termina
l regions of the polyprotein. Computer-assisted comparison of coat proteins
of OLRSV and other nepoviruses disclosed relationships that tally with sub
grouping based on physicochemical properties.
