Organic acid complexation, heavy metal distribution and the effect of ATPase inhibition in hairy roots of hyperaccumulator plant species.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

Heavy metal uptake and distribution were investigated in hairy roots of the Cd hyperaccumulator, Thlaspi caerulescens, and the Ni hyperaccumulator, Alyssum bertolonii. Hairy roots of both species contained high constitutive levels of citric, malic and malonic acids. After treatment with 20 ppm Cd or

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

רק משתמשים רשומים יכולים לתרגם מאמרים

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

Mitochondria/nuclear signaling of alternative oxidase gene expression occurs through distinct pathways involving organic acids and reactive oxygen species.

התחבר הרשם

Cultured cells of tobacco (Nicotiana tabacum L. cv Petit Havana) were used to investigate signals regulating the expression of the "model" nuclear gene encoding the alternative oxidase (AOX) (AOX1), the terminal oxidase of the mitochondrial alternative respiratory pathway. Several conditions shown

Metabolic engineering of tomato fruit organic acid content guided by biochemical analysis of an introgression line.

Organic acid content is regarded as one of the most important quality traits of fresh tomato (Solanum lycopersicum). However, the complexity of carboxylic acid metabolism and storage means that it is difficult to predict the best way to engineer altered carboxylic acid levels. Here, we used a

Activation of potassium released from soil by root-secreted organic acids in different varieties of tobacco (Nicotiana tabacum).

Organic acids secreted from the roots of plants play important roles in nutrient acquisition and metal detoxification; however, the precise underlying mechanisms of these processes remain poorly understood. In the present study we examined the content of organic acids exuded from roots and the

Relationships between Cadmium, Zinc, Cd-Peptide, and Organic Acid in Tobacco Suspension Cells.

התחבר הרשם

Responses of tobacco (Nicotiana tabacum) suspension cells to Cd and Zn were studied in the presence and absence of ligand of Cd-peptide in order to understand the role of this peptide versus other mechanisms in Cd and Zn accumulation and accommodation in plants. With 45 micromolar Cd and 300

Evaluation of the effect of small organic acids on phytoextraction of Cu and Pb from soil with tobacco Nicotiana tabacum.

התחבר הרשם

Phytoremediation, the use of plants to extract contaminants from soils and groundwater, is a promising approach for cleaning up soils contaminated with heavy metals. However its use is limited by the time required for plant growth, the nutrient supply and, moreover, by the limited metal uptake

Virus-induced gene silencing of plastidial soluble inorganic pyrophosphatase impairs essential leaf anabolic pathways and reduces drought stress tolerance in Nicotiana benthamiana.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

The role of pyrophosphate in primary metabolism is poorly understood. Here, we report on the transient down-regulation of plastid-targeted soluble inorganic pyrophosphatase in Nicotiana benthamiana source leaves. Physiological and metabolic perturbations were particularly evident in chloroplastic

Metabolic flux phenotype of tobacco hairy roots engineered for increased geraniol production.

התחבר הרשם

The goal of this study was to characterise the metabolic flux phenotype of transgenic tobacco (Nicotiana tabacum) hairy roots engineered for increased biosynthesis of geraniol, an intermediate of the terpenoid indole alkaloid pathway. Steady state, stable isotope labelling was used to determine flux

Influence of starch deficiency on photosynthetic and post-photosynthetic carbon isotope fractionations.

התחבר הרשם

Carbon isotope (13C) fractionations occurring during and after photosynthetic CO2 fixation shape the carbon isotope composition (δ13C) of plant material and respired CO2. However, responses of 13C fractionations to diel variation in starch metabolism in the leaf are not fully understood. Here we

Modified alkaloid pattern in developing tobacco callus.

התחבר הרשם

Developing Nicotiana tabacum L. cv. Wisconsin-38 callus grown on modified Murashige-Skoog (MS) medium with Kao organic acids (pyruvic, citric, malic and fumaric acids) contains abnormally high levels of nornicotine and total alkaloids when compared with the leaves of the donor plant.

Oxalate metabolism by tobacco leaf discs.

התחבר הרשם

The turnover rate of oxalate in leaf discs of Nicotiana tabacum, var Havana Seed, during photosynthesis was estimated to be 1 to 2 micromoles per gram fresh weight per hour. Radioactivity from the enzymic oxidation of [(14)C]oxalate rapidly appeared in neutral sugars (mainly sucrose), organic acids

Inorganic nitrogen requirements during shoot organogenesis in tobacco leaf discs.

התחבר הרשם

The role of nitrate, ammonium, and culture medium pH on shoot organogenesis in Nicotiana tabacum zz100 leaf discs was examined. The nitrogen composition of a basal liquid shoot induction medium (SIM) containing 39.4 mM and 20.6 mM was altered whilst maintaining the overall ionic balance with Na(+)

Abscisic Acid Stimulated Osmotic Adjustment and Its Involvement in Adaptation of Tobacco Cells to NaCl.

התחבר הרשם

Osmotic adjustment of cultured tobacco (Nicotiana tabacum L. var Wisconsin 38) cells was stimulated by 10 micromolar (+/-) abscisic acid (ABA) during adaptation to water deficit imposed by various solutes including NaCl, KCl, K(2)SO(4), Na(2)SO(4), sucrose, mannitol, or glucose. The maximum

Expression of root glutamate dehydrogenase genes in tobacco plants subjected to boron deprivation.

Recently it has been reported that boron (B) deficiency increases the expression of Nicotiana tabacum asparagine synthetase (AS) gene in roots, and that AS might play a main role as a detoxifying mechanism to convert ammonium into asparagine. Interestingly, glutamate dehydrogenase (GDH) genes,
