Influence of clock gene homologs and Pseudomonas spp. on Verticillium dahliae development and host plant interaction
(2024-08-09)The soil-borne phytopathogenic fungus Verticillium dahliae requires a tight regulation to form different developmental structures for infection, colonization of the plant vasculature and survival in soil. The fungal life ... -
Towards the identification and functional characterization of molecular components involved in PEN2-mediated entry control of non-adapted powdery mildews in Arabidopsis
(2021-08-05)The Arabidopsis thaliana cytochrome P450 monooxygenase CYP81F2 and the myrosinase PENE-TRATION2 (PEN2) are important components for broad-spectrum pre-invasion defense against filamentous plant pathogens, including non-adapted ... -
Analysis of the role of Arabidopsis extra-large G protein 2 in cerk1-4-dependent cell death signalling
(2021-06-24)Plants perceive microbe-associated molecular patterns (MAMPs) via so called pattern-recognition receptors (PRRs) at the plasma membrane, which activates an immune response. Heterotrimeric G proteins are intracellular signal ... -
Two cysteine-rich receptor-like protein kinases, CRK7 and CRK43, are required for CERK1-4 dependent cell death responses in Arabidopsis thaliana
(2020-09-22)Plants recognize potential pathogens via conserved molecular patterns. These are perceived by plasma membrane-associated receptor complexes leading to downstream signaling and activation of the plant immune system. In ... -
Cell-specific phytohormone responses mapped by the COLORFUL-biosensors during plant-microbe interactions
(2020-08-11)Plants are concurrently challenged by various invaders that can severely affect their development and productivity. Salicylic acid (SA), jasmonic acid (JA) and ethylene (ET)-dependent defense pathways are generally regarded ... -
Towards the identification and functional characterization of Verticillium effectors involved in xylem hyperplasia formation in Arabidopsis
(2020-05-26)Isolates of the vascular plant pathogen Verticillium spp. can be categorized according to the disease phenotypes they induce on Arabidopsis thaliana Col-0 plants (Thole 2016). While Arabidopsis plants show no obvious disease ... -
Characterization of Populus x canescens LysM-Receptor Like Kinases LYK4/LYK5 and LysM-Receptor Like Protein LYM2 and their Roles in Chitin Signaling
(2020-03-10)Poplar is a model tree to study the molecular biology of woody plant species. It also has commercial benefits as it is used as a renewable energy resource. Poplar plantations suffer from poplar rusts caused by Melampsora ... -
Functional analysis of the Arabidopsis thaliana glutaredoxin ROXY9
(2019-05-24)Glutaredoxins are nearly ubiquitious small enzymes which protect the thiol groups of cellular proteins from oxidative stress, contribute to iron-sulfur cluster biogenesis or regulate protein activities via redox modification. ... -
Sphingolipids in <i>Physcomitrella patens</i>
(2019-05-10)The model organism Physcomitrella patens is a bryophyte in the group of non-vascular plants. Evolutionary, bryophytes evolved shortly after the event when plants developed the ability to grow on land. P. patens can therefore ... -
Metabolic fate of jasmonates
(2019-01-21)Jasmonoyl-isoleucine (JA-Ile) is a phytohormone that orchestrates responses to wounding, feeding insects or necrotrophic pathogens in plants. JA-Ile-metabolism has been studied intensively (Wasternack, 2015) and most of ... -
Identification of Arabidopsis genes involved in differential interaction phenotype establishment by distinct Verticillium spp. and isolates
(2018-04-20)Verticillium longisporum induces developmental reprogramming of A. thaliana Col-0 leading to transdifferentiation of chloroplast-containing bundle sheath cells to functional xylem elements. Moreover, re-initiation of cambial ... -
Plant-specific glutaredoxin ROXY9 regulates hyponastic growth by inhibiting TGA1 function
(2017-04-04)In the rosette plant Arabidopsis thaliana, different environmental cues trigger upward (hyponastic) leaf movement which is evolutionary beneficial when it comes to avoid shading by neighboring plants. Hyponasty results ... -
Towards the identification of Verticillium effector molecules involved in host plant developmental reprogramming
(2016-05-26)Infections of Arabidopsis thaliana Col-0 plants with the Verticillium longisporum isolate VL43 and the Verticillium dahliae isolate VdJR2 results in clearly distinguishable disease symptoms, which are characterized by early ... -
Analysis of CERK1 ectodomain shedding and the role of XLG2 in cerk1-4 cell death execution
(2016-05-20)Conserved microbial signatures are perceived via plasma membrane localized pattern recognition receptors (PRRs). In Arabidopsis, perception of the fungal cell wall component chitin requires the LysM receptor-like kinase ... -
Analysis of the subcellular behavior of Arabidopsis thaliana LysM-proteins and their role in plant innate immunity
(2016-04-20)Health and survival of all higher eukaryotic organisms depend on efficient pathogen detection and rapid activation of defense mechanisms. Plants detect potential pathogens by recognizing conserved microbial molecules, ... -
The role of the putative receptor-like cytoplasmic kinase CLR1 in chitin signalling
(2016-01-19)Plants detect potential pathogens by perception of conserved microbe-associated molecular patterns (MAMPs) through plasma membrane-localized receptors. Signalling initiated by these receptors is a key process of plant ... -
