Abstract:
:A protocol was established for the introduction of DNA into embryogenic suspension-derived tissues of cassava via microparticle bombardment, for the selection of genetically transformed cells, and for the regeneration of fully transgenic plants from these cells. The plasmid DNA used for bombardment contained a gene encoding neomycin phosphotransferase (nptII) and a gene encoding beta-glucuronidase (uidA). Selection of bombarded tissue with paromomycin resulted in the establishment of putative transgenic embryogenic calli. In most of these calli, beta-glucuronidase was detected histochemically. Molecular analysis of paromomycin-resistant embryogenic calli and of plants regenerated from these calli, confirmed the stable integration of bombarded DNA into the cassava genome.
