Abstract
Experimental parameters for direct gene transfer with recombinant DNA encoding neomycin phosphotransferase II (NPTII) under control of eukaryotic expression signals were established. The introduced gene was shown by the growth of transformants on media containing kanamycin, by genomic blotting and by assaying NPTII activity. Leaf protoplasts from three green genotypes of varieties xanthii and petit havanna, and from four plastome-encoded albino genotypes of Nicotiana tabacum were analyzed with respect to cell division kinetics and yield of kanamycin-tolerant colonies after direct gene transfer. No clear correlation was found between the time of onset of cell division and transformation frequency.Entities:
