Characterization of CYCLOPHILLIN38 shows that a photosynthesis-derived systemic signal controls lateral root emergence
(American Society of Plant Biologists, 2021)
Photosynthesis in leaves generates fixed-carbon resources and essential metabolites that support sink tissues, such as roots. Two of these metabolites, sucrose and auxin, promote growth in root systems, but the explicit ...

NTRC-dependent redox balance of 2-Cys peroxiredoxins is needed for optimal function of the photosynthetic apparatus
(National Academy of Sciences, 2017)
Thiol-dependent redox regulation allows the rapid adaptation of chloroplast function to unpredictable changes in light intensity. Traditionally, it has been considered that chloroplast redox regulation relies on ...

A chloroplast redox relay adapts plastid metabolism to light and affects cytosolic protein quality control
(American Society of Plant Biologists, 2021)
In chloroplasts, thiol-dependent redox regulation is linked to light since the disulfide reductase activity of thioredoxins (Trxs) relies on photo-reduced ferredoxin (Fdx). Furthermore, chloroplasts harbor an NADPH-dependent ...

Redox-control of chlorophyll biosynthesis mainly depends on thioredoxins
(Wiley-Blackwell, 2018)
In order to maintain enzyme stability and activity, chloroplasts use two systems of thiol-disulfide reductases for the control of redox-dependent properties of proteins. Previous studies have revealed that plastid-localized ...

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 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, ...

Plastid 2-Cys peroxiredoxins are essential for embryogenesis in Arabidopsis
(Elsevier, 2023)
The redox couple formed by NADPH-dependent thioredoxin reductase C (NTRC) and 2-Cys peroxiredoxins (Prxs) allows fine-tuning chloroplast performance in response to light intensity changes. Accordingly, the Arabidopsis 2cpab ...

NADPH Thioredoxin Reductase C and Thioredoxins Act Concertedly in Seedling Development
(American Society of Plant Biologists, 2017)
Thiol-dependent redox regulation of enzyme activity plays a central role in the rapid acclimation of chloroplast metabolism to ever-fluctuating light availability. This regulatory mechanism relies on ferredoxin reduced ...
