| micropropagation by tissue culture triggers differential expression of infectious endogenous banana streak virus sequences (ebsv) present in the b genome of natural and synthetic interspecific banana plantains. | the genome of musa balbisiana spp. contains several infectious endogenous sequences of banana streak virus (ebsv). we have shown previously that in vitro micropropagation triggers the activation of infectious ebsolv (endogenous sequences of banana streak obino l'ewai virus) in the synthetic tetraploid interspecific hybrid fhia21 (aaab). in this work, we show that another synthetic tetraploid (aaab) hybrid and two natural triploid (aab) plantains are equally prone to the activation of infectious ... | 2010 | 20078782 |
| identification of genetic markers linked to banana streak disease expression in inter-specific musa hybrids. | recently-introduced inter-specific musa hybrids, bred for improved yield and resistance to diseases, have been found to be widely infected with banana streak virus (bsv), the causal agent of banana streak disease (bsd). one hypothesis suggests: (1) that bsd occurrence in these inter-specific hybrids results from activation of bsv-ol endogenous pararetrovirus sequences (eprv) integrated into the musa genome rather than from external sources of infection, and (2) that the process of genetic hybrid ... | 2003 | 12595986 |
