Arabidopsis K+ transporter HAK5-mediated high-affinity root K+ uptake is regulated by protein kinases CIPK1 and CIPK9
(Oxford University Press, 2020)
The high-affinity K+ transporter HAK5 is the major contributor to root K+ uptake from dilute solutions in K+-starved Arabidopsis plants. Its functionality is tightly regulated and its activity is enhanced under K+ starvation ...

Persulfidation is the mechanism underlying sulfide-signaling of autophagy
(Taylor & Francis, 2021)
In this commentary, we highlight the findings described in a recent paper regarding the mechanism of H2S regulation of macroautophagy/autophagy in mammalian cells and discuss the similarities/divergencies with plant cells. ...

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 ...

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 ...

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 ...

Persulfidation protects from oxidative stress under nonphotorespiratory conditions in Arabidopsis
(Wiley-Blackwell, 2023)
Hydrogen sulfide is a signaling molecule in plants that regulates essential biological processes through protein persulfidation. However, little is known about sulfide-mediated regulation in relation to photorespiration. ...

Hydrogen sulfide action in the regulation of plant autophagy
(Wiley-Blackwell, 2022)
Hydrogen sulfide is a signalling molecule with a well-established impact on both plant and animal physiology. Intense investigation into the regulation of autophagy by sulfide in Arabidopsis thaliana has revealed that the ...

Proposed mechanism for regulation of H2O2-induced programmed cell death in plants by binding of cytochrome c to 14-3-3 proteins
(Wiley-Blackwell, 2021-04)
Programmed cell death (PCD) is crucial for development and homeostasis of all multicellular organisms. In human cells, the double role of extra-mitochondrial cytochrome c in triggering apoptosis and inhibiting survival ...
