Cultivo de tejidos by International Center for Tropical Agriculture

“…A routine "cleaning-up" program consists of: (1) disinfestation of stakes containing dormant buds and treatment with thermotherapy; (2) cutting and disinfestation of shoot terminal buds; (3) isolation of meristem tips (0.5-0.6 mm) under sterile conditions and planting in culture medium; (4) transfer of meristem tips and nodes grown from the meristem to a rooting medium; (5) hardening of rooted plantlets prior to potting; (6) transplant to the field and to the greenhouse; (7) evaluation of the presence of frog skin disease after 3 mo. of growth; and (8) selection of symptom-free plants, grown again for 3 mo., and reevaluated. …”

PCR-DGGE analysis: unravelling complex mixtures of badnavirus sequences present in yam germplasm by Turaki, A.A., Bömer, M., Silva, G., Kumar, P. Lava, Seal, S.E.

“…Badnavirus sequences can be integrated in host genomes, complicating the detection of episomal infections and the assessment of viral genetic diversity in samples containing a complex mixture of sequences. Yam (Dioscorea spp.) plants are hosts to a diverse range of badnavirus species, and recent findings have suggested that mixed infections occur frequently in West African yam germplasm. …”
