The Functional Relationship between NADPH Thioredoxin Reductase C, 2-Cys Peroxiredoxins, and m-Type Thioredoxins in the Regulation of Calvin–Benson Cycle and Malate-Valve Enzymes in Arabidopsis
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-05-03)
The concerted regulation of chloroplast biosynthetic pathways and NADPH extrusion via malate valve depends on f and m thioredoxins (Trxs). The finding that decreased levels of the thiol-peroxidase 2-Cys peroxiredoxin (Prx) ...

Thioredoxin f1 and NADPH-dependent thioredoxin reductase C have overlapping functions in regulating photosynthetic metabolism and plant growth in response to varying light conditions
(American Society of Plant Biologists, 2015)
Two different thiol-redox-systems exist in plant chloroplasts, the ferredoxin-thioredoxin system, which depends of ferredoxin reduced by the photosynthetic electron-transport chain and, thus, of light, and the NADPH-dependent ...

Molecular recognition in the interaction of chloroplast 2-Cys peroxiredoxin with NADPH-thioredoxin reductase C (NTRC) and thioredoxin x
(Elsevier, 2014)
In addition to the standard NADPH thioredoxin reductases (NTRs), plants hold a plastidic NTR (NTRC), with a thioredoxin module fused at the C-terminus. NTRC is an efficient reductant of 2-Cys peroxiredoxins (2-Cys Prxs). ...

The contribution of glutathione peroxidases to chloroplast redox homeostasis in Arabidopsis
(Elsevier, 2023-07)
Oxidizing signals mediated by the thiol-dependent peroxidase activity of 2-Cys peroxiredoxins (PRXs) plays an essential role in fine-tuning chloroplast redox balance in response to changes in light intensity, a function ...

An intermolecular disulfide-based light switch for chloroplast psbD gene expression in Chlamydomonas reinhardtii
(Taylor & Francis, 2012)
Expression of the chloroplast psbD gene encoding the D2 protein of the photosystem II reaction center is regulated by light. In the green alga Chlamydomonas reinhardtii, D2 synthesis requires a high-molecular-weight complex ...

A gibberellin-induced nuclease is localized in the nucleus of wheat aleurone cells undergoing programmed cell death
(The American Society for Biochemistry and Molecular Biology, 2003)
The aleurone layer of cereal grains undergoes a gibberellin-regulated process of programmed cell death (PCD) following germination. We have applied a combination of ultrastructural and biochemical approaches to analyze ...

The chloroplast NADPH thioredoxin reductase C, NTRC, controls non-photochemical quenching of light energy and photosynthetic electron transport in Arabidopsis
(Wiley-Blackwell, 2016)
High irradiances may lead to photooxidative stress in plants, and non-photochemical quenching (NPQ) contributes to protection against excess excitation. One of the NPQ mechanisms, qE, involves thermal dissipation of the ...

An event of alternative splicing affects the expression of the NTRC gene, encoding NADPH-thioredoxin reductase C, in seed plants
(Elsevier, 2017)
The NTRCgene encodes aNADPH-dependentthioredoxin reductase with a joint thioredoxin domain, exclusive ofphotosynthetic organisms. An updated search of NTRCgenesshows that althoughmost species harbor a single ...

The NADPH-Dependent thioredoxin reductase C-2-Cys peroxiredoxin redox system modulates the activity of thioredoxin x in arabidopsis chloroplasts
(Oxford University Press, 2018)
The chloroplast redox network is composed of a complex set of thioredoxins (Trxs), reduced by ferredoxin (Fdx) via a Fdx-dependent Trx reductase (FTR), and an NADPH-dependent Trx reductase with a joint Trx domain, NTRC, ...

Current knowledge on mechanisms preventing photosynthesis redox imbalance in plants
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Photosynthesis includes a set of redox reactions that are the source of reducing power and energy for the assimilation of inorganic carbon, nitrogen and sulphur, thus generating organic compounds, and oxygen, which supports ...
