Signaling in the plant cytosol: cysteine or sulfide?
(Springer, 2015)
Cysteine (Cys) is the first organic compound containing reduced sulfur that is synthesized in the last stage of plant photosynthetic assimilation of sulfate. It is a very important metabolite not only because it is crucial ...

Inhibition of Arabidopsis O-acetylserine (Thiol)lyase A1 by tyrosine-nitration
(American Society for Biochemistry and Molecular Biology, 2011)
The last step of sulfur assimilation is catalyzed by O-acetylserine(thiol)lyase (OASTL) enzymes. OASTLs are encoded by a multigene family in the model plant Arabidopsis thaliana. Cytosolic OASA1 enzyme is the main source ...

PRC1 is taking the lead in PcG repression
(Blackwell Publishing, 2015-03-06)
Polycomb group (PcG) proteins constitute a major epigenetic mechanism for gene repression throughout the plant life. For a long time, the PcG mechanism has been proposed to follow a hierarchical recruitment of PcG repressive ...

Arabidopsis thaliana plastoglobule-associated fibrillin 1a interacts with fibrillin 1b in vivo
(wiley, 2014)
Plant fibrillins are a well-conserved protein family found in the plastids of all photosynthetic organisms, where they perform a wide range of functions. A number of these proteins have been suggested to be involved in the ...

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, ...

Enhancing the expression of starch synthase class IV results in increased levels of both transitory and long-term storage starch
(Wiley Open Access, 2011)
Starch is an important renewable raw material with an increasing number of applications.Several attempts have been made to obtain plants that produce modified versions of starchor higher starch yield. Most of the approaches ...

Hydrogen sulfide regulates the cytosolic/nuclear partitioning of glyceraldehyde-3-phosphate dehydrogenase by enhancing its nuclear localization
(Oxford University Press, 2017)
Hydrogen sulfide is an important signaling molecule comparable with nitric oxide and hydrogen peroxide in plants. The underlying mechanism of its action is unknown, although it has been proposed to be S-sulfhydration. This ...

The Arabidopsis E3 Ubiquitin Ligase HOS1 Negatively Regulates CONSTANS Abundance in the Photoperiodic Control of Flowering
(American Society of Plant Biologists, 2016)
The Arabidopsis thaliana early in short days6 (esd6) mutant was isolated in a screen for mutations that accelerate flowering time. Among other developmental alterations, esd6 displays early flowering in both long- and ...

Hydrogen Sulfide Signaling in Plants: Emerging Roles of Protein Persulfidation
(Frontiers Media, 2018)
Hydrogen sulfide (H2S) has been largely referred as a toxic gas and environmental hazard, but recent years, it has emerged as an important gas-signaling molecule with effects on multiple physiological processes in both ...

S-sulfocysteine synthase function in sensing chloroplast redox status
(Taylor & Francis, 2013)
The minor chloroplastic O-acetylserine(thiol)lyase isoform encoded by the CS26 gene in Arabidopsis thaliana has been described as an S-sulfocysteine synthase enzyme that plays an important role in chloroplast function. ...
