“…The complete nucleotide sequence of TomRSV RNA2 has been determined and was shown to code for the coat protein (Rott et al, 1991a), a putative cell-to-cell movement protein (Wieczorek & Sanfacon, 1993) and an N-terminal polyprotein(s) of unknown function(s). The sequences of approximately 1.1 and 1.5 kb at the 5' and 3' termini, respectively, of TomRSV RNA1 have been previously described and show near perfect nucleotide sequence identity with corresponding sequences at the 5' and 3' termini of RNA2 (Rott et al, 1991b).…”

The nucleotide sequence of tomato ringspot nepovirus (TomRSV) RNA1 has been determined. TomRSV RNA1 is 8214 nucleotides in length, excluding the 3' poly(A) tail, and contains a single long open reading frame (ORF) of 6591 nucleotides beginning at the first AUG codon at nucleotide position 78. This ORF accounts for 80 % of the RNA1 sequence and would give rise to a polyprotein with a predicted molecular mass of 244 kDa. Amino acid sequence comparisons between portions of the TomRSV RNAl-encoded polyprotein and proteins encoded by several members of the picornavirns superfamily have provided information concerning the genomic organization and putative functions of TomRSV-encoded proteins. The putative TomRSV protease retains a conserved histidine residue present in the proteases encoded by members of the como-, poty-and poliovirus groups which is thought to be involved in dipeptide cleavage site recognition. Interestingly, this histidine residue is replaced by a leucine in the proteases of other sequenced nepoviruses. This suggests that the TomRSV protease shares dipeptide cleavage site specificity with that of como-, potyand picornaviruses rather than the other nepoviruses.

Nucleotide sequence of the coat protein genes of strawberry latent ringspot virus: lack of homology to the nepoviruses and comoviruses

The sequence of the 3'-terminal 2424 nucleotides of RNA-2 of the flowering cherry strain of strawberry latent ringspot virus (SLRV) was determined from eDNA clones. The sequence contains a reading frame in the virus-sense strand of 2070 nucleotides, a 3' untranslated region of 552 nucleotides and a T-terminal poly(A) tract. The positions of the two coat proteins of SLRV within the reading frame were determined from sequence data obtained by N-terminal sequencing using Edman degradation. The larger coat protein with an M r of 43K is located 5' of the smaller coat protein of 27K, and the two proteins are apparently cleaved at a Ser-Gly bond. Although there are numerous similarities between SLRV and the nepoviruses and comoviruses, there is no significant homology between the SLRV coat proteins and the coat proteins of either group. Furthermore, the hydropathy profiles of the SLRV coat proteins are unlike those of either group. No comparisons could be made with the fabaviruses owing to lack of sequencing information. This lack of homology suggests that SLRV is more distantly related to the nepoviruses and comoviruses than has been considered previously.
