Sulfide as a signaling molecule in autophagy
(Taylor & Francis, 2013)
Hydrogen sulfide is already recognized as an important signaling molecule in mammalian systems, and emerging data suggest that H2S is a signaling molecule just as important as nitric oxide (NO) and H2O2 in plants. Although ...

Arabidopsis thaliana telomeres exhibit euchromatic features
(Oxford University Press, 2011)
Telomere function is influenced by chromatin structure and organization, which usually involves epigenetic modifications. We describe here the chromatin structure of Arabidopsis thaliana telomeres. Based on the study of ...

Analysis of the epigenetic status of telomeres by using ChIP-seq data
(Oxford University Press, 2012)
The chromatin structure of eukaryotic telomeres plays an essential role in telomere functions. However, their study might be impaired by the presence of interstitial telomeric sequences (ITSs), which have a widespread ...

CONSTANS and the evolutionary origin of photoperiodic timing of flowering
(Oxford University Press, 2011)
A network of promoting and inhibiting pathways that respond to environmental and internal signals controls the flowering transition. The outcome of this regulatory network establishes, for any particular plant, the correct ...

Photoperiodic control of sugar release during the floral transition: What is the role of sugars in the florigenic signal?
(Landes Bioscience, 2015)
Florigen is a mobile signal released by the leaves that reaching the shoot apical meristem (SAM), changes its developmental program from vegetative to reproductive. The protein FLOWERING LOCUS T (FT) constitutes an important ...

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 ...

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 ...

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 ...

Sulfide promotes tolerance to drought through protein persulfidation in Arabidopsis
(Oxford University Press, 2023-08-17)
Hydrogen sulfide (H2S) is a signaling molecule that regulates essential plant processes. In this study, the role of H2S during drought was analysed, focusing on the underlying mechanism. Pretreatments with H2S before ...
