Changes in Protein Turn-over Rates Regulate Tryptophan and Glucosinolate Biosynthesis, IAA Transport and Photosynthesis in Arabidopsis Growth and Defense Transitions

M. Abukhalaf, C. Proksch, D. Thieme, J. Ziegler, W. Hoehenwarter

The paper measures protein synthesis and degradation rates in Arabidopsis during growth and defense transitions, finding that protein turnover, not just mRNA levels, drives changes in key metabolic and immune pathways.

Prioritization of abiotic and biotic plant stress responses through ABI1 phosphatase and CPK5 calcium-dependent protein kinase switch

H. Seybold, J. Bortlik, X. Jiang, A. Liese, B. Conrads, W. Hoehenwarter, S. Matschi, T. Romeis

This paper identifies a biochemical switch involving ABI1 phosphatase and CPK5 kinase that prioritizes abiotic over biotic stress responses in plants through reversible phosphorylation at T98.

Bacterial-type plant ferroxidases tune local phosphate sensing in root development

C. Naumann, M. Heisters, W. Brandt, P. Janitza, C. Alfs, N. Tang, A. T. Nienguesso, J. Ziegler, R. Imre, K. Mechtler, Y. Dagdas, W. Hoehenwarter, G. Sawers, M. Quint, S. Abel

The paper shows that bacterial-type ferroxidases in Arabidopsis thaliana modulate phosphate sensing in roots by regulating iron homeostasis and growth under phosphate limitation.

LC-MS Based Draft Map of the Arabidopsis thaliana Nuclear Proteome and Protein Import in Pattern Triggered Immunity

M. Ayash, M. Abukhalaf, D. Thieme, C. Proksch, M. Heilmann, M. Schattat, W. Hoehenwarter

The paper uses LC-MS to map the Arabidopsis thaliana nuclear proteome under untreated and PTI conditions, identifying putatively imported proteins and changes in nuclear abundance.

Reshaping of the Arabidopsis thaliana proteome landscape and co-regulation of proteins in development and immunity

M. Bassal, P. Majovsky, D. Thieme, T. Herr, M. Abukhalaf, M. Ayash, M. R. Al Shweiki, C. Proksch, A. Hmedat, J. Ziegler, S. Neumann, W. Hoehenwarter

The paper quantifies the Arabidopsis thaliana proteome across its lifecycle and identifies co-regulated proteins in development and immunity, revealing new roles for transcription factors and signaling modules.

Phosphorylation of the CAMTA3 transcription factor triggers its destabilization and nuclear export.

X. Jiang, W. Hoehenwarter, D. Scheel, J. Lee

Flg22 activates two kinase pathways that phosphorylate and degrade CAMTA3, removing it from target promoters to de-repress defense genes.

Flexibility of intrinsically disordered degrons in AUX/IAA proteins reinforces auxin co-receptor assemblies

M. Niemeyer, E. Moreno Castillo, C. H. Ihling, C. Iacobucci, V. Wilde, A. Hellmuth, W. Hoehenwarter, S. L. Samodelov, M. D. Zurbriggen, P. L. Kastritis, A. Sinz, L. I. A. Calderon Villalobos

The paper investigates how flexible intrinsically disordered regions in AUX/IAA proteins modulate auxin receptor assemblies by positioning AUX/IAAs on TIR1 for ubiquitylation.

Phosphorylation of the exocyst subunit Exo70B2 contributes to the regulation of its function

O.-K. Teh, C.-W. Lee, F. A. Ditengou, T. Klecker, G. Furlan, M. Zietz, G. Hause, L. Eschen-Lippold, W. Hoehenwarter, J. Lee, T. Ott, M. Trujillo

This study shows that phosphorylation of Exo70B2 regulates its function in secretion and immunity by modulating its localization and interaction with the secretory pathway.
