Characterization of Populus x canescens LysM Receptor-Like Kinases CERK1-1 and CERK1-2 and their Role in Chitin Signaling
(2022-03-22)Poplar trees have been established as a model organism to study woody perennial plants. The first fully sequenced tree species was Populus trichocarpa. Nevertheless, for experiments in the laboratory often other Populus ... -
Community structure and guild patterns of soil decomposers in pure and mixed forests of European beech, Norway spruce and Douglas fir
(2021-10-28)Anthropogenic global warming is creating new challenges for forest management in many parts of the world. One vital aspect is the choice of tree species and whether to cultivate monospecific or mixed timber plantations. ... -
The velvet protein Vel1 controls initial plant root colonization and conidia formation for xylem distribution in Verticillium wilt
(2021-08-24)The velvet family of regulatory proteins is well-conserved in fungi and links developmental processes and secondary metabolite production. These proteins comprise a velvet domain for DNA binding and dimerization with ... -
Antagonistic fluorescent pseudomonads cause evasion of the plant pathogen Verticillium by controlling hyphal growth and polarity
(2021-04-09)Abstract Soil borne phytopathogenic Verticillia constitute increasing yield losses. Due to a lack of resistant cultivars as well as appropriate fungicides, the usage of biocontrol agents like fluorescent pseudomonads might ... -
Impact of rainforest conversion: How prokaryotic communities respond to anthropogenic land use changes
(2020-12-03)In this thesis, the impact of rainforest conversion to the managed land use systems jungle rubber, rubber plantation and oil palm plantation on structure and function of soil microbial communities was investigated. The ... -
Compositional and functional shifts in belowground fungal communities in tropical land-use systems
(2020-06-23)Tropical low-land rainforests are one of the most diverse ecosystems in the world and provide valuable ecosystem services such as climate change mitigation. They are immensely threatened by expanding human land-use. ... -
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 ... -
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. ... -
Functional study of potential sHSPs in Arabidopsis and tomato under environmental stress.
(2019-05-10)Small heat shock proteins (sHSPs) respond to many environmental stresses, stabilizing early unfolding protein intermediates and avoiding their irreversible aggregation. In plants, organellar sHSPs are a unique cellular ... -
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 ... -
Impact of Rain Forest Transformation on Roots and Functional Diversity of Root-Associated Fungal Communities
(2017-12-07)Tropical rain forests are representing biodiversity hotspots, but their species richness is threatened by human driven land use changes. Between 1990 and 2015 most of the global deforestation of about 129 million hectares ... -
Land-use Control on Abiotic and Biotic Mechanisms of P Mobilization
(2017-10-13)Phosphorus (P) is the most limiting nutrient for plant growth and productivity in many regions worldwide especially in the tropics. Aside intrinsic low P availability controlled by physicochemical and biological reactions, ... -
Phosphorus nutrition of poplar
(2017-05-29)Phosphorus (P) is a major plant nutrient required for the biosynthesis of nucleic acids, nucleotides, membrane lipids and metabolites such as organic esters. P further plays a role in enzyme regulation by phosphorylation. ... -
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 ... -
Molecular analysis of importin-α-mediated nucleocytoplasmic signaling in plant innate immunity
(2015-04-30)IMPORTIN-αs are a family of nuclear transport receptors that mediate the translocation of nuclear localization signal (NLS)-containing cargo proteins from the cytoplasm into the nucleus through nuclear pores. The IMPORTIN-α3, ... -
Roles of the Cpc1 regulator of the cross-pathway control in the Verticillium plant pathogens
(2014-06-20)Verticillium longisporum is a soil-borne fungal pathogen of oilseed rape (Brassica napus). Infection is initiated by hyphae from germinating microsclerotia which invade the plant vascular system through penetration of the ... -
The sumoylation and neddylation networks in Aspergillus nidulans development
(2013-10-22)Proteins can be post-translationally modified by the attachment of members of the ubiquitin-like protein family which requires the action of three enzymatic steps. The protein becomes activated by an E1 enzyme, transferred ... -
Signals and metabolic consequences during the interaction of Brassicaceae and <i>Verticillium longisporum</i>
(2013-01-14)The soil-borne, hemibiotrophic pathogen Verticillium longisporum is a severe threat for oilseed rape (Brassica napus) cultivation. In order to develop effective, defensive treatments for infected plants a thorough understanding ... -
Arabidopsis thaliana class II TGA transcription factors provide a molecular link between salicylic acid and ethylene defense signalling
(2011-11-15)Since plants are exposed to a multitude of different attackers, a complex innate immune system has evolved to protect them from devastating diseases. Depending on the type of pathogen or ... -
