| properties of a virus causing mosaic and leaf curl disease of celosia argentea l. in nigeria. | a sap transmissible virus, causing mosaic and leaf curl disease of celosia argentea, was isolated at vegetable farms in amuwo odofin, tejuoso, and abule ado, lagos, nigeria. the virus had a restricted host range confined to a few species of the amaranthaceae, chenopodiaceae and solanaceae families. it failed to infect several other species of the aizoaceae, brassicaceae, cucurbitaceae, fabaceae, lamiaceae, malvaceae, poaceae and tiliaceae families. the virus was transmitted in a non-persistent m ... | 1998 | 9842442 |
| ultrastructural localization of nonstructural and coat proteins of 19 potyviruses using antisera to bacterially expressed proteins of plum pox potyvirus. | antisera to the bacterially expressed nonstructural proteins (nsp) hc-pro, ci, nia, and nib and the coat protein (cp) of plum pox potyvirus (ppv) were used for analysing the composition of virus-induced cytoplasmic and nuclear inclusions by electron microscopy. the antisera reacted with nsp and cp of ppv on immunogold-labelled ultrathin sections. antiserum to cp reacted with virions of seven out of 18 other potyviruses. cp was distributed throughout the cytoplasm of infected cells. antisera to p ... | 1998 | 9856098 |

| the complete nucleotide sequence, genome organization, and specific detection of beet mosaic virus. | beet mosaic virus (btmv) was identified almost five decades ago but has not been fully characterized at the molecular level. in this study, we have determined for the first time the complete nucleotide sequence of btmv genomic rna and have developed a specific molecular means for its diagnosis. the viral genome of btmv comprises 9591 nucleotides, excluding the 3' terminal poly (a) sequence, and contains a single open reading frame (orf) that begins at nt 166 and terminates at nt 9423, encoding a ... | 2004 | 15168206 |
| molecular characterization of two chinese isolates of beet mosaic virus. | the complete genomic sequences of beet mosaic virus xinjiang (btmv-xj) and inner mongolia (btmv-im) isolates from china were determined and compared with us and german isolates, reported previously. results showed that viral genome of the two isolates both comprise 9,591 nucleotides, and contain the large single open reading frame (orf) encoding a single polyprotein of 3,085 amino acid residues, from which ten putative functional proteins may be produced by autolytic cleavage processing as the u ... | 2007 | 17671838 |
| molecular analysis of the 3' terminal region of the genome of beet mosaic virus and its relation with other potyviruses. | a1633 nucleotides long 3'-terminal sequence of genome of the beet mosaic virus (btmv) ren1 isolate from slovakia, spanning a part of the nib gene, complete capsid protein (cp) gene and a 3'non-coding region was determined. computer-assisted translation resulted in a polypeptide encompassing typical conserved potyviral amino acid (aa) motifs. homology blast search and phylogenetic analysis revealed that btmv was closest to bean common mosaic virus, soybean mosaic virus and zucchini yellow mosaic ... | 2003 | 14505096 |
