Journal ArticleDOI
S-nitrosylation: an emerging post-translational protein modification in plants.
Jeremy Astier,Sumaira Rasul,Emmanuel Koen,Hamid Manzoor,Angélique Besson-Bard,Olivier Lamotte,Sylvain Jeandroz,Joerg Durner,Christian Lindermayr,David Wendehenne +9 more
TL;DR: A review of efforts made in the identification of plant proteins modified by NO at the post-translational level, notably by S-nitrosylation, as well as the Biotin Switch Technique and its recent adaptations, to describe the basic principle and impact on the structure/function of selected proteins.
Journal ArticleDOI
Nitric oxide production mediates oligogalacturonide-triggered immunity and resistance to Botrytis cinerea in Arabidopsis thaliana.
Sumaira Rasul,C. Dubreuil-Maurizi,C. Dubreuil-Maurizi,Olivier Lamotte,Emmanuel Koen,Emmanuel Koen,Benoît Poinssot,Benoît Poinssot,G. Alcaraz,David Wendehenne,David Wendehenne,Sylvain Jeandroz +11 more
TL;DR: It is demonstrated that NO modulates RBOHD-mediated reactive oxygen species (ROS) production and participates in the regulation of OG-responsive genes such as anionic peroxidase (PER4) and a β-1,3-glucanase and that L-NAME affected NO production by interfering with NR activity, thus questioning the mechanisms of how this compound impairs NO synthesis in plants.
Journal ArticleDOI
Protein S-nitrosylation: what's going on in plants?
Jeremy Astier,Anna Kulik,Anna Kulik,Emmanuel Koen,Emmanuel Koen,Angélique Besson-Bard,Angélique Besson-Bard,Stéphane Bourque,Stéphane Bourque,Sylvain Jeandroz,Olivier Lamotte,David Wendehenne,David Wendehenne +12 more
TL;DR: There is now compelling experimental evidence that NO partly operates through posttranslational modification of proteins, notably via S-nitrosylation and tyrosine nitration and these discoveries greatly extend knowledge of NO functions and of the molecular processes inherent to signal transduction in plants.
Journal ArticleDOI
Nitrate efflux is an essential component of the cryptogein signaling pathway leading to defense responses and hypersensitive cell death in tobacco.
TL;DR: The results indicate that anion channels are involved intimately in mediating defense responses and hypersensitive cell death in tobacco plants.
Journal ArticleDOI
Mechanisms of nitric-oxide-induced increase of free cytosolic Ca2+ concentration in Nicotiana plumbaginifolia cells.
Olivier Lamotte,Cécile Courtois,Grażyna Dobrowolska,Angélique Besson,Alain Pugin,David Wendehenne +5 more
TL;DR: Evidence is provided that NO might activate plasma membrane Ca(2+) channels by inducing a rapid and transient plasma membrane depolarization and that NtOSAK was activated in response to hyperosmotic stress through a NO-dependent process, supporting the hypothesis that NO also promotes protein kinase activation during physiological processes.
