| sequence analysis of the 3' termini of rna1 and rna2 of blueberry leaf mottle virus. | the 3' termini of rna1 and rna2 of blueberry leaf mottle virus (bblmv) were cloned and the cdna sequence of a portion of the putative polymerase gene, the complete coat protein (cp) gene, and the 3' non-coding regions was determined. the n terminus of the coat protein gene was precisely located by comparison with the amino acid sequence determined by the edman degradation sequencing of the purified coat protein. the coat protein gene encoded a polypeptide of 521 amino acids with a predicted m(r) ... | 1994 | 7975879 |
| characterization of the coat protein gene of mite-transmitted blackcurrant reversion associated nepovirus. | the nucleotide sequence of the 3' terminal 3105 nucleotides (nt) of rna2 of blackcurrant reversion associated virus (brav), the first mite-transmitted member of the nepovirus group, has been determined. the sequence contains an open reading frame of 1744 nt in the virus-sense strand, a 3' untranslated region of 1360 nt and a 3' poly(a) tail. analysis of the amino-terminal residues of purified coat protein (cp) suggests that the cp gene is located between nts 1361 and 2959 (from the 3' terminus) ... | 1998 | 9617765 |
| complete nucleotide sequence and genome organisation of grapevine bulgarian latent virus. | the complete genome sequence of grapevine bulgarian latent virus (gblv) has been determined. rna-1 (7,452 nt in length) contains a single orf of 6,285 nt, encoding a polyprotein with conserved motifs characteristic of the viral protease cofactor (prot-cofact), the ntp-binding protein (ntp), the cysteine-like protease (cyst-prot) and the rna-dependent rna polymerase (rdrp) of members of the order picornavirales and show high aa sequence identity with blackcurrant reversion virus (brv, 64%). rna-2 ... | 2011 | 21243380 |
| selection versus recombination: what is maintaining identity in the 3' termini of blueberry leaf mottle nepovirus rna1 and rna2? | the 3' non-coding regions (ncr) of rna1 and rna2 of blueberry leaf mottle nepovirus (bblmv) are nearly identical with differences occurring at only four positions. the presence of this 1.4 kb duplication indicates that recombination has occurred at least once in the evolutionary history of bblmv. since high mutation rates are common in rna viruses, strong selection pressure and/or high frequency of recombination must be operating in order to maintain identity in this duplicated region. the possi ... | 1994 | 8046421 |
