ProteomicsCRK2-mediated control of ROS production by phosphorylation of the RBOHD C-terminus in Arabidopsis
Reactive oxygen species (ROS) are important messengers in eukaryotic organisms. Extracellular ROS production by NADPH oxidases in plants is triggered by receptor-like protein kinase (RLK)-dependent signaling networks. This ROS production is tightly controlled by multiple mechanisms including phospho...

ProteomicsFlorigen activation complex forms via multifaceted assembly in Arabidopsis
'Florigen', encoded by FT genes, is synthesized in leaves and transported to the shoot apical meristem (SAM) to induce flower development. At the SAM, 14-3-3 proteins are proposed to act as receptors for FT and to mediate the indirect interaction between FT and the bZIP transcription factor FD to fo...

ProteomicsUstilago maydis disrupts carbohydrate signaling networks to induce hypertrophy in maize mesophyll cells (total and phospho proteome data)
Ustilago maydis is a biotrophic fungus that infects arial parts of maize, secreting effector proteins to facilitate host colonization and manipulate cellular processes, creating nutrient-rich environments for its growth and reproduction. Here, we identified three effectors (Hap1-3; hypertrophy-assoc...

ProteomicsPhosphoproteomics of Arabidopsis seedlings under carbon/nitrogen-nutrient stress
Nutrient availability, in particular that of carbon (C) and nitrogen (N), is one of the most important factors for the regulation of plant metabolism and development. In addition to independent utilization, the ratio of C to N metabolites in the cell is also important for the regulation of plant gro...

ProteomicsCATALASE INTERACTING RCC1-LIKE 1 contributes to hydrogen peroxide homeostasis in Arabidopsis
Reactive oxygen species (ROS) are central regulators of plant growth and stress responses, and their cellular levels are tightly controlled by antioxidant systems, including the evolutionarily conserved catalases that decompose hydrogen peroxide (H2O2) predominantly within peroxisomes and glyoxysome...

ProteomicsOXI1 coordinates programmed cell death by promoting salicylic acid, N-hydroxypipecolic acid and reactive oxygen species accumulation in Arabidopsis
The protein kinase OXI1 is induced by a large number of stress conditions and regulates the interaction of plants with pathogenic and beneficial microbes but little is yet known on the underlying mechanisms. In this work, we generated Arabidopsis OXI1 knock out and overexpression lines and show by t...

ProteomicsActive protein ubiquitination regulates xylem vessel functionality
Xylem vessels function in the long-distance conduction of water in land plants. The NAC transcription factor VASCULAR-RELATED NAC-DOMAIN7 (VND7) is a master regulator of xylem vessel cell differentiation in Arabidopsis (Arabidopsis thaliana). We previously isolated seiv (suppressor of ectopic xylem ...

ProteomicsSts2, a transcriptional activator effector of Ustilago maydis, regulates hyperplasia in maize during pathogen-induced tumor formation
Ustilago maydis causes common smut in maize, which is characterized by tumor formation in aerial parts of maize. Tumor comes from the de novo cell division of highly developed bundle sheath and subsequent cell enlargement. However, its mechanism is still unknown. Here, we characterize the U. maydis ...

Here, we define the proteomic response of the early divergent liverwort Marchantia polymorpha during infection with the oomycete pathogen Phytophthora palmivora. We sampled whole liverwort thalli that were mock-inoculated (water) or infected with P. palmivora zoospores at 4 and 8 days post inoculati...

Gene regulation of bacterial pathogens in the host is not comprehensively understood due to the difficulty in analyzing genome-wide mRNA and protein expression of bacteria during infection. Here, we jointly analyzed transcriptome and proteome of a foliar bacterial pathogen in plants. Bacterial trans...
