The Lysin Motif Receptor-like Kinase (LysM-RLK) CERK1 Is a Major Chitin-binding Protein in Arabidopsis thaliana and Subject to Chitin-induced Phosphorylation
Elena Petutschnig,Elena Petutschnig,Alexandra M. E. Jones,Liliya Serazetdinova,Ulrike Lipka,Volker Lipka,Volker Lipka +6 more
TL;DR: The data suggest that in Arabidopsis, CERK1 is a major chitin, chitosan, and chito-oligomer binding component and that chit in signaling depends on CERk1 post-translational modification and kinase activity.

AvrPtoB targets the LysM receptor kinase CERK1 to promote bacterial virulence on plants.
Selena Gimenez-Ibanez,Dagmar R. Hann,Vardis Ntoukakis,Elena Petutschnig,Volker Lipka,John P. Rathjen +5 more
TL;DR: This work shows that the Arabidopsis LysM receptor kinase CERK1, which is critical for chitin elicitor signaling and resistance to fungal pathogens, plays an essential role in restricting bacterial growth on plants and reveals a new pathway for plant immunity against bacteria.

Broad-Spectrum Suppression of Innate Immunity Is Required for Colonization of Arabidopsis Roots by the Fungus Piriformospora indica
Sophie Jacobs,Bernd Zechmann,Alexandra Molitor,Marco Trujillo,Elena Petutschnig,Volker Lipka,Karl-Heinz Kogel,Patrick Schäfer +7 more
TL;DR: In this paper, the authors show that P. indica is confronted with a functional root immune system and that its ability to suppress host immunity is compromised by various microbe associated molecular patterns (MAMPs).
LYM2-dependent chitin perception limits molecular flux via plasmodesmata
Christine Faulkner,Christine Faulkner,Elena Petutschnig,Yoselin Benitez-Alfonso,Martina Beck,Silke Robatzek,Volker Lipka,Andrew J. Maule +7 more
TL;DR: Chitin-triggered regulation of molecular flux between cells is required for defense responses against the fungal pathogen Botrytis cinerea, and thus it is concluded that the regulation of symplastic continuity and molecular flux at plasmodesmata flux is a vital component of chitin's triggered immunity in Arabidopsis.

Stress-Induced GSK3 Regulates the Redox Stress Response by Phosphorylating Glucose-6-Phosphate Dehydrogenase in Arabidopsis
Silvia Dal Santo,Hansjörg Stampfl,Julia Krasensky,Stefan Kempa,Yves Gibon,Elena Petutschnig,Wilfried Rozhon,Alexander Heuck,Tim Clausen,Claudia Jonak +9 more
TL;DR: It is shown that a Glycogen Synthase Kinase3 from Arabidopsis thaliana (ASKα) regulates stress tolerance by activating Glc-6-phosphate dehydrogenase (G6PD), which is essential for maintaining the cellular redox balance.
