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 کاملFusion of farnesyldiphosphate synthase and epi-aristolochene synthase, a sesquiterpene cyclase involved in capsidiol biosynthesis in Nicotiana tabacum.
A clone encoding farnesyl diphosphate synthase (FPPS) was obtained by PCR from a cDNA library made from young leaves of Artemisia annua. A cDNA clone encoding the tobacco epi-aristolochene synthase (eAS) was kindly supplied by J. Chappell (University of Kentucky, Lexington, KY, USA). Two fusions were constructed, i.e. FPPS/eAS and eAS/FPPS. The stop codon of the N-terminal enzyme was removed an...
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...
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 کاملGlutathione Transferase from Trichoderma virens Enhances Cadmium Tolerance without Enhancing Its Accumulation in Transgenic Nicotiana tabacum
BACKGROUND Cadmium (Cd) is a major heavy metal pollutant which is highly toxic to plants and animals. Vast agricultural areas worldwide are contaminated with Cd. Plants take up Cd and through the food chain it reaches humans and causes toxicity. It is ideal to develop plants tolerant to Cd, without enhanced accumulation in the edible parts for human consumption. Glutathione transferases (GST) a...
