High-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 کاملHigh-frequency transformation of undeveloped plastids in tobacco suspension cells.
Although leaf chloroplast transformation technology was developed more than a decade ago, no reports exist of stable transformation of undeveloped plastids or other specialized plastid types, such as proplastids, etioplasts, or amyloplasts. In this work we report development of a dark-grown tobacco suspension cell model system to investigate the transformation potential of undeveloped plastids....
متن کاملHigh-efficiency transformation of mammalian cells by plasmid DNA.
We describe a simple calcium phosphate transfection protocol and neo marker vectors that achieve highly efficient transformation of mammalian cells. In this protocol, the calcium phosphate-DNA complex is formed gradually in the medium during incubation with cells and precipitates on the cells. The crucial factors for obtaining efficient transformation are the pH (6.95) of the buffer used for th...
متن کاملCysteine transport into cultured tobacco cells.
Cysteine transport by tobacco cells (Nicotiana tabacum L. var. Xanthi) cultured on liquid B-5 medium was examined.Transport was linear with time or amount of tissue and had a pH optimum of 4.5. Cysteine transport over a wide concentration range was biphasic. The isotherm, for descriptive convenience, was divided into two segments both of which obeyed Michaelis-Menten kinetics. The Km for high a...
متن کاملSulfate transport in cultured tobacco cells.
Sulfate transport by tobacco (Nicotiana tabacum L. var. Xanthi) cells cultured on either l-cysteine or sulfate as a sole sulfur source was measured. The transport rate on either sulfur source was low during pre-exponential growth, increased during exponential growth, and was maximal in late exponential cells. The initial increase in transport rate was correlated with a decline in the intracellu...
