| genomic characterisation of taro bacilliform virus. | taro bacilliform virus (tabv) has been classified as a putative badnavirus based on its non-enveloped, bacilliform virion morphology and transmission by mealybugs. the complete nucleotide sequence of a papua new guinea isolate of tabv has now been determined and comprises 7458 bp. the genome contains four open reading frames (orfs) on the plus-strand that potentially encode proteins of 17, 16, 214 and 13 kda. the size and organisation of tabv orfs 1-3 is similar to that of most other badnaviruse ... | 2003 | 12721801 |
| molecular analysis of a full-length sequence of a new yam badnavirus from dioscorea sansibarensis. | badnavirus-like particles were observed by isem in viral preparations from yam (dioscorea sansibarensis) leaves from benin. use of the viral preparation as template for pcr amplification with badnavirus-specific primers gave rise to a 579-bp product with most nucleotide identity (70.8%) to dioscorea alata bacilliform virus (dabv, accession numbers x94575-x94582), the only other yam badnavirus sequenced to date. a full-length badnavirus sequence was generated, which consisted of 7261 nucleotides ... | 2007 | 17195956 |
| molecular analysis of the complete genomic sequences of four isolates of gooseberry vein banding associated virus. | the presence of gooseberry vein banding associated virus (gvbav), a badnavirus in the family caulimoviridae, is strongly correlated with gooseberry vein banding disease in ribes spp. in this study, full-length genomic sequences of four gvbav isolates from different hosts and geographic regions were determined to be 7649-7663 nucleotides. these isolates share identities of 96.4-97.3% for the complete genomic sequence, indicating low genetic diversity among them. the gvbav genome contains three op ... | 2011 | 21533750 |
| sequence diversity among badnavirus isolates infecting yam (dioscorea spp.) in ghana, togo, benin and nigeria. | we analysed the sequence diversity in the reverse transcriptase (rt)/ribonuclease h (rnaseh) coding region of 19 badnavirus isolates infecting yam (dioscorea spp.) in ghana, togo, benin, and nigeria. phylogenetic analysis of the deduced amino acid sequences revealed that the isolates are broadly divided into two distinct species, each clustering with dioscorea alata bacilliform virus (dabv) and dioscorea sansibarensis bacilliform virus (dsbv). fourteen isolates had 90-96% amino acid identity wit ... | 2008 | 19030955 |
| analysis of the sequence of dioscorea alata bacilliform virus: comparison to others members of the badnavirus group. | the complete nucleotide sequence of the genome of dioscorea alata bacilliform virus (dabv) has been determined from cloned fragments. features of the genome confirm dabv to be a pararetrovirus of the genus badnavirus which is more similar to other mealy-bug transmitted badnaviruses, in particular to cacao swollen shoot virus, than to rice tungro bacilliform virus. sequence variability between cloned fragments suggests that the genetic variability of the virus may be quite high (up to 11% nucleot ... | 1999 | 10456795 |
