Journal ArticleDOI
Thioredoxin and glutaredoxin systems in plants: molecular mechanisms, crosstalks, and functional significance
Yves Meyer,Christophe Belin,Valérie Delorme-Hinoux,Jean-Philippe Reichheld,Christophe Riondet +4 more
TL;DR: Interestingly, recent development integrating biochemical analysis, proteomic data, and genetics have revealed an extensive crosstalk between the cytosolic NTR/Trx and GSH/Grx systems, which reveals the high plasticity of the redox systems in plants.
Journal ArticleDOI
Inactivation of Thioredoxin Reductases Reveals a Complex Interplay between Thioredoxin and Glutathione Pathways in Arabidopsis Development
Jean-Philippe Reichheld,Mehdi Khafif,Christophe Riondet,Michel Droux,Géraldine Bonnard,Yves Meyer +5 more
TL;DR: Interestingly, plants of the ntra ntrb knockout mutant are viable and fertile, although with a wrinkled seed phenotype, slower plant growth, and pollen with reduced fitness, demonstrating that neither cytosolic nor mitochondrial NTRs are essential in plants.
Journal ArticleDOI
Thioredoxin, a master regulator of the tricarboxylic acid cycle in plant mitochondria
Danilo M. Daloso,Danilo M. Daloso,Karolin Müller,Toshihiro Obata,Alexandra Florian,Takayuki Tohge,Alexandra Bottcher,Christophe Riondet,Laetitia Bariat,Fernando Carrari,Adriano Nunes-Nesi,Bob B. Buchanan,Jean-Philippe Reichheld,Wagner L. Araújo,Alisdair R. Fernie +14 more
TL;DR: In vivo confirmation of earlier in vitro results and further show that mitochondria resemble plastids in using TRX and redox status to regulate the main carbon flux pathway of the organelle, finding TRX to be a redox-sensitive mediator of TCA cycle flux.
Journal ArticleDOI
A comprehensive study of thiol reduction gene expression under stress conditions in Arabidopsis thaliana.
Christophe Belin,Talaat Bashandy,Jana Cela,Valérie Delorme-Hinoux,Christophe Riondet,Jean-Philippe Reichheld +5 more
TL;DR: By collecting information from gene expression databases, this work has performed a comprehensive in silico study of the expression of all members of different classes of thiol reduction genes (TRX, GRX) in Arabidopsis thaliana.
Journal ArticleDOI
NTR/NRX define a new thioredoxin system in the nucleus of arabidopsis thaliana cells
Corinne Marchal,Valérie Delorme-Hinoux,Laetitia Bariat,Wafi Siala,Wafi Siala,Christophe Belin,Julio Sáez-Vásquez,Christophe Riondet,Jean-Philippe Reichheld +8 more
TL;DR: It is shown that Arabidopsis thaliana has two NRX genes (AtNRX1 and AtNRX2), respectively, belonging to subgroups I and III, and it is found that NTRA, previously identified as a cytosolic protein, is also partially localized in the nucleus, suggesting that a complete TRX system is functional inThe nucleus.
