An apparent K(m) value of 3.6x10(-5)m was foun...
متن کاملHigh-Efficiency Agrobacterium-Mediated Transformation of Tobacco (Nicotiana tabacum)
To improve Agrobacterium-mediated transformation of tobacco, factors influencing gene delivery, including genotype of the plant, bacterial strain, and Agrobacterium transformation procedure, were tested via direct somatic embryogenesis. Leaf tissue of three different tobacco genotypes (Nicotiana tabacum L. cvs. Samsun, and Xanthi, and N. benthamiana) we...
متن کاملGenetics of Burley and Flue-Cured Tobacco Resistance to Globodera tabacum tabacum.
Genotypes of burley (cultivars B-21 and B-49), flue-cured (line VA-81 and cultivar PD-4), and Connecticut broadleaf (cultivar C9) tobacco (Nicotiana tabacum) resistant (R) or susceptible (S) to the tobacco cyst nematode Globodera tabacum tabacum were crossed.

متن کاملPurine metabolism in mesophyll protoplasts of tobacco (Nicotiana tabacum) leaves.
The overall metabolism of purines was studied in tobacco (Nicotiana tabacum) mesophyll protoplasts. Metabolic pathways were studied by measuring the conversion of radioactive adenine, adenosine, hypoxanthine and guanine into purine ribonucleotides, ribonucleosides, bases and nucleic acid constituents. Adenine was extensively deaminated to hypoxanthine, whereupon it was also converted into AMP a...
