| biology, etiology, and control of virus diseases of banana and plantain. | banana and plantain (musa spp.), produced in 10.3 million ha in the tropics, are among the world's top 10 food crops. they are vegetatively propagated using suckers or tissue culture plants and grown almost as perennial plantations. these are prone to the accumulation of pests and pathogens, especially viruses which contribute to yield reduction and are also barriers to the international exchange of germplasm. the most economically important viruses of banana and plantain are banana bunchy top v ... | 2015 | 25591881 |
| detection of banana mild mosaic virus and banana virus x by polyvalent degenerate oligonucleotide rt-pcr (pdo-rt-pcr). | viruses are important constraints to the movement and propagation of plant germplasm, especially for vegetatively propagated crops such as banana and plantain. their control relies primarily on the use of virus-free plant material, whose production and certification requires sensitive and reliable detection methods. an existing polyvalent degenerate oligonucleotide rt-pcr (pdo-rt-pcr) assay was adapted to the detection of banana mild mosaic virus (banmmv) and banana virus x, two flexiviridae inf ... | 2007 | 17280722 |
| high genetic variability and evidence for plant-to-plant transfer of banana mild mosaic virus. | a total of 154 partial nucleotide sequences within the banana mild mosaic virus (banmmv) orf1, which encodes the viral rna-dependent rna polymerase (rdrp), was obtained from 68 distinct infected banana accessions originating from various locations worldwide. the 310 nt sequences displayed a high level of variability with a mean pairwise nucleotide sequence divergence level of 20.4 %. this situation resulted essentially from a high rate of synonymous mutations. a similar analysis was performed fo ... | 2005 | 16227242 |
| molecular characterisation of banana mild mosaic virus, a new filamentous virus in musa spp.. | banana mild mosaic virus (banmmv) is a previously undescribed filamentous virus infecting musa spp. the complete genome has been sequenced from pcr clones and consists of 7352 nucleotides, encoding five open reading frames (orfs) of 205, 25.5, 12.4, 8.0 and 26.8 kda, respectively. banmmv was most closely related to fovea- and carlaviruses, based on phylogenetic analysis using a portion of the viral replicase. analysis of other parts of the genome revealed similarities with fovea-, carla- and pot ... | 2001 | 11556712 |
