| nucleotide sequence of coat protein gene of yam mild mosaic virus, isolated in papua new guinea. | we determined the 3'-termimus 1353 nucleotides (nts) in length excluding the poly (a) tail of yam mild mosaic potyvirus (ymmv) rna. the sequence starts within a long open reading frame (orf) 1209 nts and is followed by untranslated region (3'-utr) of 144 nts. the coat protein (cp) contains 266 amino acids (aa) with molecular ratio (mr) of approximately 30 kda. the cp of ymmv differs substantially from yam mosaic virus (ymv), japanese yam mosaic virus (jymv) (57 and 61% of amino acid sequence ide ... | 1999 | 10481747 |
| characterisation of a potyvirus and a potexvirus from chinese scallion. | molecular analyses of viruses infecting chinese scallion (allium chinense g. don) showed that the plants did not contain any of the poty-, carla- or allexiviruses that are common in garlic plants in china. the complete sequences of a potyvirus and a potexvirus were determined and these were shown to represent different viruses from any in the databases. they could be transmitted mechanically to scallion but not to other allium species (including garlic) or to narcissus. the potyvirus, tentativel ... | 2002 | 12038680 |
| potyviruses, novel and known, in cultivated and wild species of the family apiaceae in australia. | three potyviruses were identified by gene sequencing and found to be widespread in species of apiaceae in australia. only celery mosaic virus was found in celery crops and in one of 180 specimens of feral carrot ( daucus carota). another related but distinct novel potyvirus, carrot virus y, was the only virus found in carrot crops and all except one feral carrot. a more distantly related novel potyvirus, apium virus y, was found in plants of sea celery ( apium prostratum), cultivated parsley ( p ... | 2002 | 12376749 |
| the phylogeny of turnip mosaic virus; comparisons of 38 genomic sequences reveal a eurasian origin and a recent 'emergence' in east asia. | the genomes of a representative world-wide collection of 32 turnip mosaic virus (tumv) isolates were sequenced and these, together with six previously reported sequences, were analysed. at least one-fifth of the sequences were recombinant. in phylogenetic analyses, using genomic sequences of japanese yam mosaic virus as an outgroup, the tumv sequences that did not show clear recombination formed a monophyletic group with four well-supported lineages. these groupings correlated with differences i ... | 2003 | 12859632 |
| konjak mosaic virus: the complete nucleotide sequence of the genomic rna and its comparison with other potyviruses. | konjak mosaic virus (komv) belongs to the genus potyvirus, family potyviridae. the complete nucleotide sequence of komv f isolate (komv f) was determined. the genome is 9,544 nucleotides long excluding the 3' terminal poly a tail and encodes a typical potyviral 350-kda polyprotein of 3,087 amino acids. phylogenetic analysis using known potyvirus polyproteins shows that komv constitutes a branch with yam mosaic virus, close to another branch including japanese yam mosaic virus, turnip mosaic viru ... | 2006 | 16538420 |
| complete genome sequence of a divergent strain of japanese yam mosaic virus from china. | a novel strain of japanese yam mosaic virus (jymv-cn) was identified in a yam plant with foliar mottle symptoms in china. the complete genomic sequence of jymv-cn was determined. its genomic sequence of 9701 nucleotides encodes a polyprotein of 3247 amino acids. its organization is virtually identical to that of two jymv isolates from japan. with the latter, it shares nucleotide sequence identities of only 74.7-74.8 %, indicating it might be a member of a new species. however, sequence analysis ... | 2015 | 25244960 |
| detection of japanese yam mosaic virus by rt-lamp. | arapid and simple procedure is described to detect the genomic rna molecule of japanese yam mosaic potyvirus (jymv). this method, named rt-lamp, allows direct detection of rna from infected plants without careful rna extraction, rapid thermal cycling and gel electrophoresis. rt-lamp was successfully applied to leaves, propagules and roots of japanese yam infected with jymv. one of the characteristics of the rt-lamp method is its ability to synthesize an extremely large amount of dna. accordingly ... | 2003 | 14505084 |
| complete nucleotide sequence of the genomic rna of a japanese yam mosaic virus, a new potyvirus in japan. | we determined the complete nucleotide sequence of a potyvirus purified from a japanese yam plant. the genomic rna of this virus is 9,757 nucleotides (nts) in length, excluding the 3'-terminal poly(a) tail. it contains a single open reading frame (orf) encoding a polyprotein of 3130 amino acids (aa) with a calculated mr of 356,793. the genomic organization of this potyvirus is similar to that of other members of the genus potyvirus and nine potential cleavage sites for the viral proteinase were f ... | 1999 | 10470250 |
