Antimicrobial 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 کاملMonograph 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 کاملRibulose-1,5-bisphosphate carboxylase/oxygenase activase cDNAs from Nicotiana tabacum.
Rubisco-the key regulatory enzyme in photosynthetic carbon assimilation-is activated in vivo by the chloroplast enzyme Rubisco activase (Portis, 1990). Previous studies in which Rubisco antisense DNA mutants of tobacco were used have revealed that under some circumstances Rubisco activase can play a central role in regulating the photosynthetic process (Rodermel et al., 1988; Quick et al., 1991...

متن کاملLipopolysaccharide-responsive phosphoproteins in Nicotiana tabacum cells.
Mounting evidence is merging to affirm the effectiveness of bacterial lipopolysaccharides (LPS) as biological control agents, inducers of innate immunity, and to stimulate/potentiate the development of defense responses in plants through protein phosphorylation-mediated signal perception/transduction responses. In vivo labeling of protein phosphorylation events during signal transduction indica...
