The complete mRNA sequence of one tobacco (nicotiana tabacum) gene—guanosine monophosphate (GMP)synthase, was amplified using the rapid amplification cDNA ends methods. full-length GMP synthase gene 2,127bp containing a 1,617 bp open reading frame, which encodes protein 538 amino acids. Sequence analysis revealed that shares high homology with wood tobacco(99%), nicotiana attenuata(99%), toment...

Effects of excess concentrations of boron on major cell wall components of tobacco cells(Nicotiana tabacum L. cv. Burley 21) were studied. Pectin, xyloglucan, hydroxyproline-richglycoproteins (extensin), and arabinogalactan proteins were characterized. Results showedthat increased boron supply resulted in significant decrease in cell and cell wall dry weights.Also, high concentrations of boron ...

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...

Tobacco (Nicotiana tabacum L.) is a plant grown for leaves. Leaves are dried and fermented to use in tobacco products. Oriental widely consumed the world due its good aroma qualities. For this, different chemical quality properties of lines, which have undergone small changes over time, been examined. The samples (27 lines 1 variety (Xanthi 2A)) obtained from three locations (Bagpinar, Evciler ...

BACKGROUND: Nicotiana tobacco contains large amounts of alkaloid nicotine. Tobacco plant is used for smoking and causes many health problems since it is high in nicotine which is one of the widely-recognized toxic compounds with serious side effects for different body organs. Reducing nicotine content of this plant is a way to reduce its health hazards in cigarette smokers. Utilizing the new ...

Abstract Background Weather change in high-altitude areas subjects mature tobacco ( Nicotiana tabacum L.) to cold stress, which damages leaf yield and quality. A brupt diurnal temperature differences (the daily dropping more than 20 °C) along with rainfall tobacco-growing at an altitude above 2450 m, caused stress field-grown tobacco. Results After the flue-cured suffered field, surface color o...

Tobacco products, including cigarettes, cigars, chewing tobacco, snuff, and loose pipe tobacco, contain the dried, processed leaves of the tobacco plant Nicotiana rustica or Nicotiana tabacum. All forms of tobacco contain nicotine, an extremely addictive drug that can act as both a central nervous system stimulant and depressant. In addition to nicotine, tobacco contains thousands of other chem...

Nicotiana tabacum commonly known as Tobacco plant which has broad application over soap, paint and cigar industries was now investigated for biodiesel production. Nicotiana tabacum seeds were one of the prominent sources for non-edible oil. Oil from Tobacco seeds were expelled with Soxhlet extraction apparatus using n-hexane as extraction solvent. Two stage trans-esterification has been adopted...
