The role of phenolic compounds in growth improvement of cultured tobacco cells after exposure to 2-D clinorotation
Previous studies have confirmed that the growth and development of plants are entirely dependent on the gravitational acceleration of the Earth. So far, most of the studies on the plant response to the Earth gravity have focused on the geotropism of root tip of higher plants<span lang="AR-SA" dir="RTL...
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...
متن کاملCysteine metabolism in cultured tobacco cells.
Transported l-[(35)S]cysteine was rapidly metabolized by cultured tobacco cells when supplied to the cells at 0.02 millimolar or 0.5 millimolar. The internal cysteine pool was expandable to approximately 2400 nmoles per gram fresh weight.The (35)S label derived from cysteine was found in several metabolites. The amount of label in glutathione and sulfate was directly proportional to the interna...
متن کاملOn a Crystal-containing Body in Cells of the Oat Coleoptile
In the course of an experimental study of phototropism in seedlings (1, 2) attention has been directed to the plastids as possible participants in the light-detection process. This led to a microscopic study of the cells of the oat coleoptile and thence to the discovery of the body which is the subject of this note. The materials were chosen for their phototropic sensitivity. Avena sativa (oats...
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...
