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 ...

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...

ProteomicsProteomic response of the early divergent liverwort Marchantia polymorpha during infection with the oomycete pathogen Phytophthora palmivora
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...

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...

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 ...

ProteomicsIn planta bacterial multi-omics illuminates regulatory principles underlying plant-pathogen interactions
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...

ProteomicsFirst description of Botrytis cinerea Extracellular vesicles proteome: Unrevealing new tools for its infection process
Extracellular vesicles (EVs) are membranous particles released by different organisms. EVs carry several kinds of macromolecules implicated in cell communication. EVs have become an important topic in the study of pathogenic fungi, due to their relation with the fungal-host interactions. One of the ...

ProteomicsConservation and divergence of UVR8-COP1/SPA-HY5 signaling in UV-B responses of Marchantia polymorpha
Ultraviolet-B radiation (UV-B) poses a major challenge to all forms of plant life. The liverwort Marchantia polymorpha (Marchantia) serves as a key model organism to study signaling pathways and to infer their evolution throughout the green lineage. Marchantia expresses key components of UV-B signal...

ProteomicsRole of CHR4 during floral transition
Several pathways conferring environmental flowering responses in Arabidopsis converge on developmental processes that mediate floral transition in the shoot apical meristem. Many characterized mutations disrupt these environmental responses, but downstream developmental processes have been more refr...

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...
