Journal ArticleDOI
A nuclear glutathione cycle within the cell cycle
TL;DR: A high level of GSH in the nucleus may not only have an immediate effect on gene expression patterns, but also contribute to how cells retain a memory of the cellular redox environment that is transferred through generations.
Journal ArticleDOI
Recruitment of glutathione into the nucleus during cell proliferation adjusts whole‐cell redox homeostasis in Arabidopsis thaliana and lowers the oxidative defence shield
Pedro Diaz Vivancos,Yingping Dong,Kerstin Ziegler,Jelena Markovic,Federico V. Pallardó,Till K. Pellny,P. J. Verrier,Christine H. Foyer +7 more
TL;DR: In this paper, the authors show that GSH co-localizes with nuclear DNA during the proliferation of A.thaliana cells in culture and demonstrate that the GSH localization in the nucleus was observed in dividing pericycle cells of the lateral root meristem.
Journal ArticleDOI
The transcription factor ABI4 is required for the ascorbic acid-dependent regulation of growth and regulation of jasmonate-dependent defense signaling pathways in Arabidopsis.
Pavel I. Kerchev,Till K. Pellny,Pedro Diaz Vivancos,Pedro Diaz Vivancos,Guy Kiddle,Peter Hedden,Simon P. Driscoll,Hélène Vanacker,P. J. Verrier,Robert D. Hancock,Christine H. Foyer +10 more
TL;DR: It is demonstrated that low ascorbate triggers ABA- and jasmonate-dependent signaling pathways in leaves that together regulate growth through ABI4, and cellular redox homeostasis exerts a strong influence on sugar-dependent growth regulation.
Journal ArticleDOI
Perturbations of amino acid metabolism associated with glyphosate-dependent inhibition of shikimic acid metabolism affect cellular redox homeostasis and alter the abundance of proteins involved in photosynthesis and photorespiration
Pedro Diaz Vivancos,Simon P. Driscoll,Christopher A. Bulman,Liu Ying,Kaveh Emami,Achim Treumann,Caroline Mauve,Graham Noctor,Christine H. Foyer +8 more
TL;DR: It is concluded that glyphosate-dependent inhibition of soybean leaf metabolism leads to the induction of defense proteins without sustained oxidation, and the accumulation of high levels of glyphosate in RRS enhances cellular oxidation, possibly through mechanisms involving stimulation of the photorespiratory pathway.
Journal ArticleDOI
Pyridine Nucleotide Cycling and Control of Intracellular Redox State in Relation to Poly (ADP-Ribose) Polymerase Activity and Nuclear Localization of Glutathione during Exponential Growth of Arabidopsis Cells in Culture
Till K. Pellny,Vittoria Locato,Vittoria Locato,Pedro Diaz Vivancos,Jelena Markovic,Laura De Gara,Federico V. Pallardó,Christine H. Foyer +7 more
TL;DR: It is concluded that there are marked changes in intracellular redox state during the growth cycle but that redox homeostasis is maintained by interplay of the major redox pyridine nucleotides, glutathione, and ascorbate pools.
