Lack of mitochondrial and nuclear-encoded subunits of complex I and alteration of the respiratory chain in Nicotiana sylvestris mitochondrial deletion mutants.

התחבר הרשם

We previously have shown that Nicotiana sylvestris cytoplasmic male sterile (CMS) mutants I and II present large mtDNA deletions and that the NAD7 subunit of complex I (the main dehydrogenase of the mitochondrial respiratory chain) is absent in CMS I. Here, we show that, despite a large difference

Investigations of vacuoles isolated from tobacco: I. Quantitation of nicotine.

Nicotine was shown to be associated with mature vacuoles isolated from protoplasts of Nicotiana rustica. The vacuolar preparations also contained high levels of acid phosphatase, ATPase, and approximately 30% of the soluble protoplastic protein. The contamination of the vacuolar isolate by

Tissue-specific activity of two manganese superoxide dismutase promoters in transgenic tobacco.

התחבר הרשם

In eukaryotes, manganese superoxide dismutase is a nuclear-encoded protein that scavenges superoxide radicals in the mitochondrial matrix. We have isolated two manganese superoxide dismutase genes from Nicotiana plumbaginifolia L. and fused the 5' upstream regulatory region of these genes to the

Nitrogen Metabolism in Plant Cell Suspension Cultures: II. Role of Organic Acids during Growth on Ammonia.

התחבר הרשם

Tobacco cells (Nicotiana tabacum) are capable of growth on ammonia as a sole nitrogen source only when succinate, malate, fumarate, citrate, alpha-ketoglutarate, glutamate, or pyruvate is added to the growth medium. A ratio between the molar concentrations of ammonia to succinate (as a complementary

The induction of nitrogenase activity in Rhizobium by non-legume plant cells.

Nitrogen fixation was induced in a strain of "cowpea" rhizobia, 32Hl, when it was grown in association with cell cultures of the non-legume, tobacco (Nicotiana tabacum). Rhizobia grown alone on the various media examined did not show nitrogenase activity, indicating the involvement of particular

Initial organic products of assimilation of [N]ammonium and [N]nitrate by tobacco cells cultured on different sources of nitrogen.

Glutamine is the first major organic product of assimilation of (13)NH(4) (+) by tobacco (Nicotiana tabacum L. cv. Xanthi) cells cultured on nitrate, urea, or ammonium succinate as the sole source of nitrogen, and of (13)NO(3) (-) by tobacco cells cultured on nitrate. The percentage of organic (13)N

Lower growth temperature increases alternative pathway capacity and alternative oxidase protein in tobacco.

התחבר הרשם

Suspension cells of NT1 tobacco (Nicotiana tabacum L. cv bright yellow) have been used to study the effect of growth temperature on the CN-resistant, salicylhydroxamic acid-sensitive alternative pathway of respiration. Mitochondria isolated from cells maintained at 30 degrees C had a low capacity to

Alamethicin permeabilizes the plasma membrane and mitochondria but not the tonoplast in tobacco (Nicotiana tabacum L. cv Bright Yellow) suspension cells.

התחבר הרשם

The ion channel-forming peptide AlaM (alamethicin) is known to permeabilize isolated mitochondria as well as animal cells. When intact tobacco (Nicotiana tabacum L.) Bright Yellow-2 cells were treated with AlaM, the cells became permeable for low-molecular-mass molecules as shown by induced leakage

Cyanide-Resistant Respiration in Suspension Cultured Cells of Nicotiana glutinosa L.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

The respiration of dark-grown Nicotiana glutinosa L. cells in liquid suspension culture was found to be highly cyanide resistant and salicylhydroxamic acid (SHAM) sensitive, indicative of an active alternative respiratory pathway. This was especially true during the lag and logarithmic phases of the

Mitochondrial alterations related to programmed cell death in tobacco cells under aluminium stress.

התחבר הרשם

The present investigation was undertaken to verify whether mitochondria play a significant role in aluminium (Al) toxicity, using the mitochondria isolated from tobacco cells (Nicotiana tabacum, non-chlorophyllic cell line SL) under Al stress. An inhibition of respiration was observed in terms of

Production of reactive oxygen species, alteration of cytosolic ascorbate peroxidase, and impairment of mitochondrial metabolism are early events in heat shock-induced programmed cell death in tobacco Bright-Yellow 2 cells.

התחבר הרשם

To gain some insight into the mechanisms by which plant cells die as a result of abiotic stress, we exposed tobacco (Nicotiana tabacum) Bright-Yellow 2 cells to heat shock and investigated cell survival as a function of time after heat shock induction. Heat treatment at 55 degrees C triggered

A plasma membrane-bound enzyme of tobacco roots catalyses the formation of nitric oxide from nitrite.

התחבר הרשם

Purified plasma membranes (PMs) of tobacco (Nicotiana tabacum L. cv. Samsun) roots exhibited a nitrite-reducing enzyme activity that resulted in nitric oxide (NO) formation. This enzyme activity was not detected in soluble protein fractions or in PM vesicles of leaves. At the pH optimum of pH 6.0,
