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 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...
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...
متن کاملExpression of a Self-Incompatibility Glycoprotein (S2-Ribonuclease) from Nicotiana alata in Transgenic Nicotiana tabacum.
In Nicotiana alata, self-incompatibility is controlled by a single locus, designated the S-locus, with multiple alleles. Stylar products of these alleles are ribonucleases that are secreted mainly in the transmitting tract tissues. N. tabacum plants were transformed with constructs containing the S2-cDNA and genomic S2-sequences from N. alata that were linked to the cauliflower mosaic virus 35S...
