Monograph of Tobacco (nicotiana Tabacum)
The use of tobacco dates back to the ancient civilizations of the Americas, where it played a central role in religious occasions. The peoples smoked tobacco in cigars and pipes and chewed it with lime, for its pleasurable euphoriant effects. In the 16 th century, Europeans spread the use of tobacco in North America, while the Spanish bring it into Europe. In the 1559, Jean Nicot, the French am...
متن کاملAntimicrobial Activity of Nicotiana Tabacum Using Different Solvents Extracts
The present study investigates antibacterial activity of tobacco extracts from Nicotiana tabacum at different concentrations in different polar solvents. Six different extracts were prepared, using 5 different polar solvents viz., Ethanol, Ethyl acetate, n-Hexane, Acetone, Butanol and water. Four different concentrations (6, 12, 18 and 24 mg of sample disc) of each extract were subjected for pr...
متن کاملTemperature-Sensitive Variants of NICOTIANA TABACUM Isolated from Somatic Cell Culture.
Temperature-sensitive variants of Nicotiana tabacum were isolated from a liquid suspension culture of somatic cells by a negative selection procedure, using bromodeoxyuridine and light. A total of nine such variants have been recovered, with an estimated rate of 2 x 10(-7) per cell division. The appearance of the variants at the permissive temperature varied from nearly wild type, white and fri...
متن کاملBiocatalytic Asymmetric Alkene Reduction: Crystal Structure and Characterization of a Double Bond Reductase from Nicotiana tabacum
The application of biocatalysis for the asymmetric reduction of activated C=C is a powerful tool for the manufacture of high-value chemical commodities. The biocatalytic potential of "-ene" reductases from the Old Yellow Enzyme (OYE) family of oxidoreductases is well-known; however, the specificity of these enzymes toward mainly small molecule substrates has highlighted the need to discover "-e...
متن کاملInduction of Ethylene Biosynthesis in Nicotiana tabacum
Xylanase (EIX) from the fungus Trichoderma viride elicits ethylene biosynthesis in leaf tissues of Nicotiana tabacum cv Xanthi but not in cv Hicks. The increase in ethylene biosynthesis is accompanied by an accumulation of 1-aminocyclopropane-1-carboxylic acid (ACC), an increase in extractable ACC synthase activity, and increases in ACC synthase and ACC oxidase transcripts. Priming of leaves wi...
