l-Galactono-gamma-lactone dehydrogenase from Arabidopsis thaliana, a flavoprotein involved in vitamin C biosynthesis.

Only registered users can translate articles

l-Galactono-1,4-lactone dehydrogenase (GALDH; ferricytochrome c oxidoreductase; EC 1.3.2.3) is a mitochondrial flavoenzyme that catalyzes the final step in the biosynthesis of vitamin C (l-ascorbic acid) in plants. In the present study, we report on the biochemical properties of recombinant

Effects of exogenously-applied L-ascorbic acid on root expansive growth and viability of the border-like cells.

Only registered users can translate articles

Functions of exogenous L-ascorbic acid in plant roots are poorly understood. Recent study by Makavitskaya et al. (doi.org/10.1093/jxb/ery056) has demonstrated that exogenous ascorbate can be released from roots in response to salt stress, and can trigger elevation in the cytosolic free Ca2+. Here,

L-ascorbic acid metabolism in the ascorbate-deficient arabidopsis mutant vtc1.

Only registered users can translate articles

The biosynthesis of L-ascorbic acid (vitamin C) is not well understood in plants. The ozone-sensitive Arabidopsis thaliana mutant vitamin c-1 (vtc1; formerly known as soz1) is deficient in ascorbic acid, accumulating approximately 30% of wild-type levels. This deficiency could result from elevated

Engineered silver nanoparticles are sensed at the plasma membrane and dramatically modify the physiology of Arabidopsis thaliana plants.

Silver nanoparticles (Ag NPs) are the world's most important nanomaterial and nanotoxicant. The aim of this study was to determine the early stages of interactions between Ag NPs and plant cells, and to investigate their physiological roles. We have shown that the addition of Ag NPs to cultivation

Overexpression of AtOxR gene improves abiotic stresses tolerance and vitamin C content in Arabidopsis thaliana.

Only registered users can translate articles

Abiotic stresses are serious threats to plant growth, productivity and result in crop loss worldwide, reducing average yields of most major crops. Although abiotic stresses might elicit different plant responses, most induce the accumulation of reactive oxygen species (ROS) in plant cells leads to

Abscisic acid-induced modulation of metabolic and redox control pathways in Arabidopsis thaliana.

Only registered users can translate articles

Abscisic acid (ABA) has been implicated as a mediator in plant responses to various environmental stresses. To evaluate the transcriptional and metabolic events downstream of ABA perception, Arabidopsis thaliana seedlings were analyzed by transcript and metabolite profiling, and results were

Metabolic engineering of Kluyveromyces lactis for L-ascorbic acid (vitamin C) biosynthesis.

BACKGROUND L-ascorbic acid (L-AA) is naturally synthesized in plants from D-glucose by 10 steps pathway. The pathway branch to synthesize L-galactose, the key intermediate for L-ascorbic acid biosynthesis, has been recently elucidated. Budding yeast produces an 5-carbon ascorbic acid analogue

Production of L-ascorbic acid by metabolically engineered Saccharomyces cerevisiae and Zygosaccharomyces bailii.

Only registered users can translate articles

Yeasts do not possess an endogenous biochemical pathway for the synthesis of vitamin C. However, incubated with l-galactose, L-galactono-1,4-lactone, or L-gulono-1,4-lactone intermediates from the plant or animal pathway leading to l-ascorbic acid, Saccharomyces cerevisiae and Zygosaccharomyces

KONJAC1 and 2 Are Key Factors for GDP-Mannose Generation and Affect l-Ascorbic Acid and Glucomannan Biosynthesis in Arabidopsis.

Only registered users can translate articles

Humans are unable to synthesize l-ascorbic acid (AsA), yet it is required as a cofactor in many critical biochemical reactions. The majority of human dietary AsA is obtained from plants. In Arabidopsis thaliana, a GDP-mannose pyrophosphorylase (GMPP), VITAMIN C DEFECTIVE1 (VTC1), catalyzes a

A high-performance liquid chromatography radio method for determination of L-ascorbic acid and guanosine 5'-diphosphate-l-galactose, key metabolites of the plant vitamin C pathway.

Only registered users can translate articles

A simple, rapid, and quantitative high-pressure liquid chromatography radio method is described for the determination of in vivo (14)C-labeled l-ascorbate, dehydro-l-ascorbate, and total l-ascorbate of Arabidopsis thaliana cell suspensions upon incubation of cultures with exogenous d-[(14)C]mannose.

The influence of ascorbic acid on root growth and the root apical meristem in Arabidopsis thaliana.

Only registered users can translate articles

Cell division is a fundamental biological process governed by molecular networks that are initiated in the apical meristems of plants. l-ascorbic acid (AsA) commonly known as vitamin C is a crucial molecular modulator involved in cell proliferation. In this study, we used AsA application to

Manipulation of L-ascorbic acid biosynthesis pathways in Solanum lycopersicum: elevated GDP-mannose pyrophosphorylase activity enhances L-ascorbate levels in red fruit.

Only registered users can translate articles

Ascorbate (AsA) plays a fundamental role in redox homeostasis in plants and animals, primarily by scavenging reactive oxygen species. Three genes, representing diverse steps putatively involved in plant AsA biosynthesis pathways, were cloned and independently expressed in Solanum lycopersicum

Identification of ascorbic acid-deficient Arabidopsis thaliana mutants.

Only registered users can translate articles

Vitamin C (l-ascorbic acid) is a potent antioxidant and cellular reductant present at millimolar concentrations in plants. This small molecule has roles in the reduction of prosthetic metal ions, cell wall expansion, cell division, and in the detoxification of reactive oxygen generated by

GDP-mannose pyrophosphorylase is a genetic determinant of ammonium sensitivity in Arabidopsis thaliana.

Only registered users can translate articles

Higher plant species differ widely in their growth responses to ammonium (NH(4)(+)). However, the molecular genetic mechanisms underlying NH(4)(+) sensitivity in plants remain unknown. Here, we report that mutations in the Arabidopsis gene encoding GDP-mannose pyrophosphorylase (GMPase) essential

Ontogenetic changes in vitamin C in selected rice varieties.

Only registered users can translate articles

Vitamin C (L-ascorbic acid) is a key antioxidant for both plants and animals. In plants, ascorbate is involved in several key physiological processes including photosynthesis, cell expansion and division, growth, flowering, and senescence. In addition, ascorbate is an enzyme cofactor and a regulator
