Journal ArticleDOI
Structural basis for signaling by exclusive EDS1 heteromeric complexes with SAG101 or PAD4 in plant innate immunity.
Stephan Wagner,Johannes Stuttmann,Steffen Rietz,Raphael Guerois,Raphael Guerois,Elena Brunstein,Jaqueline Bautor,Karsten Niefind,Jane E. Parker +8 more
TL;DR: Although there is evolutionary conservation of α/β hydrolase topology in all three proteins, a noncatalytic resistance mechanism is indicated and the respective N-terminal domains appear to facilitate binding of the essential EP domains to create novel interaction surfaces on the heterodimer.
Journal ArticleDOI
Different roles of Enhanced Disease Susceptibility1 (EDS1) bound to and dissociated from Phytoalexin Deficient4 (PAD4) in Arabidopsis immunity.
Steffen Rietz,Anika Stamm,Stefan Malonek,Stephan Wagner,Dieter Becker,Nieves Medina-Escobar,A. Corina Vlot,Bart J. Feys,Karsten Niefind,Jane E. Parker +9 more
TL;DR: The nature and biological relevance of EDS1 interactions with PAD4 and SAG101 were explored using yeast three-hybrid assays, in vitro analysis of recombinant proteins purified from Escherichia coli, and characterization of Arabidopsis transgenic plants expressing an eds1 mutant protein.
Journal ArticleDOI
The mitochondrial complexome of Arabidopsis thaliana.
Jennifer Senkler,Michael Senkler,Holger Eubel,Tatjana M. Hildebrandt,Christian Lengwenus,Peter Schertl,Markus Schwarzländer,Stephan Wagner,Ilka Wittig,Hans-Peter Braun +9 more
TL;DR: A complexome profiling analysis for leaf mitochondria of the model plant Arabidopsis thaliana is presented for the systematic characterization of protein assemblies and several protein complexes were discovered that have not yet been reported in plants.
Journal ArticleDOI
ATP sensing in living plant cells reveals tissue gradients and stress dynamics of energy physiology
Valentina De Col,Valentina De Col,Philippe Fuchs,Thomas Nietzel,Marlene Elsaesser,Chia Pao Voon,Alessia Candeo,Ingo Seeliger,Mark D. Fricker,Christopher Grefen,Ian M. Møller,Andrea Bassi,Boon Leong Lim,Boon Leong Lim,Marco Zancani,Andreas J. Meyer,Andreas J. Meyer,Alex Costa,Stephan Wagner,Markus Schwarzländer,Markus Schwarzländer +20 more
TL;DR: Progression of hypoxia reveals substantial plasticity of ATP homeostasis in seedlings, demonstrating that ATP dynamics can be monitored in the living plant and establishing MgATP2- measurement in living plants using the fluorescent protein biosensor ATeam1.
Journal ArticleDOI
The ‘mitoflash’ probe cpYFP does not respond to superoxide
Markus Schwarzländer,Stephan Wagner,Yulia G. Ermakova,Vsevolod V. Belousov,Rafael Radi,Joseph S. Beckman,Garry R. Buettner,Nicolas Demaurex,Michael R. Duchen,Henry Jay Forman,Mark D. Fricker,David Gems,Andrew P. Halestrap,Barry Halliwell,Ursula Jakob,Iain G. Johnston,Nick S. Jones,David C. Logan,Bruce A. Morgan,Florian L. Muller,David G. Nicholls,S. James Remington,Paul T. Schumacker,Christine C. Winterbourn,Lee J. Sweetlove,Andreas J. Meyer,Tobias P. Dick,Michael P. Murphy +27 more
TL;DR: It is shown that purified cpYFP is completely unresponsive to superoxide, and that mitoflashes do not reflect superoxide generation or provide a link between mitochondrial free radical dynamics and lifespan.
