Radioactivity in tobacco leaves.

Numai utilizatorii înregistrați pot traduce articole

The radioactivity in tobacco leaves collected from 15 different regions of Greece before cigarette production was studied in order to find any association between the uptake of the naturally occurring radionuclides and the isotopes of cesium of Chernobyl origin. The activities of the isotopes of

Polysomes from expanded tobacco leaves.

Numai utilizatorii înregistrați pot traduce articole

The isolation of intact polysomes from leaves of tobacco (Nicotiana tabacum L.) is dependent on the age and state of development of leaves. Undegraded polysomes from young leaves in the early stages of expansion can be isolated easily by extracting the leaves in ice-cold extraction buffer (200 mM

Chloroplast DNA from tobacco leaves.

Numai utilizatorii înregistrați pot traduce articole

DNA from tobacco leaf chloroplasts was isolated as a single component with a buoyant density in CsCl of 1.702 compared to 1.697 for nuclear DNA. 5-Methylcytosine is present in nuclear DNA but absent in chloroplast DNA. Chloroplast DNA, with a guanine-cytosine content of 43 percent, has a melting

In Nicotiana attenuata, systemic induction of heat-shock proteins (Hsps) was detected in response to the treatment of single leaves by either heat shock, mechanical damage, or exogenous application of methyl jasmonate (MJ). All treatments increased the abundance of members of the 70-kD Hsp (Hsp70)

Functional chloroplast polyribosomes from tobacco leaves.

Numai utilizatorii înregistrați pot traduce articole

Incubation of isolated to bacco chloroplasts with ingredients re quired for protein synthesis resulted in liberation of 70S ribosomnes and poly ribosomes that no longer sedimented with the chloroplasts. With increasing time of incubation, polyribosomes broke down to 70S monosomes. Similarly,

Levels of nicotine in Ethiopian tobacco leaves.

Numai utilizatorii înregistrați pot traduce articole

Tobacco is a valuable cash crop. It is the most widely grown non-food crop in the world. Tobacco use is widespread due to its addictive nature of its main constituent nicotine. Therefore, the knowledge of nicotine level in tobacco is important to tobacco industry and in the area of toxicology to

Polyribosomes in protoplasts isolated from tobacco leaves.

Numai utilizatorii înregistrați pot traduce articole

Polyribosomes (polysomes), active in an amino acid incorporation system in vitro, were isolated from tobacco leaf protoplasts. A comparison of polysome profiles indicated that the polysome/monosome ratio is greatly decreased in isolated protoplasts as compared to the intact leaf. In isolated

Antiviral sesquiterpenes from leaves of Nicotiana tabacum.

Numai utilizatorii înregistrați pot traduce articole

Three unreported sesquiterpenes possessing two new skeletons, tabasesquiterpenes A-C (1-3), together with three known sesquiterpenes (3-6) were isolated from the leaves of Nicotiana tabacum. Their structures were determined mainly by spectroscopic methods, including extensive 1D- and 2D-NMR

A poly(U) polymerase in tobacco leaves.

Numai utilizatorii înregistrați pot traduce articole

A poly(U) polymerizing enzyme has been found in healthy and tobacco mosaic virus-infected tobacco leaves and has been partially purified by affinity chromatography on a gel prepared from agarose with chemically coupled RNA. The enzyme is stimulated by Mn-2+ and dependent on a polynucleotide,
