Background. Nanomaterials are easily modified and have unique characteristics associated with a large reactive surface Due to these properties, nanomaterials used in various branches of sciences technology, such as pharmaceuticals, biotechnology, chemical etc. Recently, the effect magnetite nanoparticles on morphological properties plants has been actively studied for their further use nanoaddi...

Fluoroaromatic compounds are used as agrochemicals and released into environment as pollutants. Glycosylation of 2-, 3-, and 4-fluorophenols using plant cell cultures of Nicotiana tabacum was investigated to elucidate their potential to metabolize these compounds. Cultured N. tabacum cells converted 2-fluorophenol into its beta-glucoside (60%) and beta-gentiobioside (10%). 4-Fluorophenol was al...

To identify the chromosome carrying the factor for resistance to Meloidogyne incognita in tobacco, crosses were made between resistant tobacco 'NC95' as pollen parent and each of the 12 tobacco monosomics (A-L) representative of the Tomentosae half of the Nicotiana tabacum chromosome complement. Of the F seedlings, 927 plants were grown for observation. From these, 223 plants were selected as p...

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...

The photosystem I complex from Nicotiana tabacum, which has an alloploid genome, contains subunits of 17.5 and 18.5 kilodaltons whose N-terminal amino acid sequences are highly homologous. Comparative analysis of photosystem I subunits among N. tabacum and its ancestral plants, N. tomentosiformis and N. sylvestris, revealed that the 17.5 kilodalton subunit of N. tabacum derives from N. sylvestr...

An amine, after dansylation, has been isolated from Nicotiana tabacum crown gall tumours for the first time and characterized as 4-hydroxy-3-methoxy-beta-phenylethylamine (3-methoxytyramine). The compound cannot be detected in differentiated N. tabacum tissues but appears in the corresponding callus controls. Its concentration is further increased 5-42-fold when N. tabacum is transformed with a...
