From glycosidase activity profiling to inhibitor discovery in the plant pathogen Pseudomonas syringae
(2018-05-25)
Retaining glycosidases are important in plants for various biological processes. Plant genomes encode for more than 200 retaining glycosidases but the physiological roles and activities of many remain poorly understood. ...
Characterization of the transcription factor ANAC058 and its role in suberin regulation
(2018-08-28)
The hydrophobic polymer suberin is present in plant roots. Its biosynthesis and composition is of importance for tolerance towards environmental stresses. In the model plant Arabidopsis thaliana transcription factors ......
Phytyl Ester Synthases from Arabidopsis thaliana and Solanum lycopersicum
(2018-07-20)
Chlorophyll is the most abundant pigment in the biosphere, and its degradation leads to the release of large amounts of chlorophyll breakdown products, i.e. pheophorbide and phytol. Only a minor fraction of the released ......
Suberin biosynthesis in barley roots in response to osmotic stress
(2018-10-31)
In future climate change will intensify extreme weather conditions, such as drought, which will lead to decreased yields of crops. A decrease in soil water potential is the first signal of potential drought stress for ...
Identification of components and substrates of Snf1-related kinase 1 (SnRK1) complexes in Arabidopsis thaliana
(2019-04-04)
Similarly to yeast Sucrose nonfermenting 1 (Snf1) and animal AMP-activated protein kinases (AMPKs), plant Snf1-related (SnRK1) kinases play a central role in the regulation of cellular energy homeostasis and responses to ......
Characterization of the Morphological and Cellular Effects of Arabidopsis thaliana Glutamate Receptor AtGLR3.7 on Plant Growth and Physiology
(2019-01-22)
There is a ubiquitous involvement of glutamate receptor-like receptors in all major physiological processes in plants and these proteins have similar operating properties as animal ionotropic glutamate receptors. The aim ...
Contribution of phenylpropanoids to the suberin barrier in roots of Arabidopsis thaliana
(2019-02-05)
The apoplastic polyester suberin forms a barrier in root endodermal and peridermal tissue. Transmission electron microscopy (TEM) displays the lamella-like structure of suberin which is divided into light (electron-translucent) ...
ABA-Dependent and -Independent Regulation of Tocopherol (Vitamin E) Biosynthesis in Response to Abiotic Stress in Arabidopsis
(2019-05-15)
Abiotic stresses in plants lead to elevated levels of reactive oxygen species that can have detrimental effects on photosystems and thylakoid lipids. To limit damage, plants increase the production of antioxidants such as ......
Silica Cell Wall Morphogenesis and Cytoskeletal Dynamics of the Centric Diatom Odontella sinensis
(2019-01-25)
The architecture and the distribution of the cytoskeleton in a diatom cell has not been systematically reported before, and its function during the cell cycle has remained largely unexplored. In this thesis, I used Odontella ...
Phylogeny, Biogeography and Systematics of Loasaceae subfam. Loasoideae
(2019-02-01)
Loasaceae subfam. Loasoideae is a mostly South American group of angiosperms that reaches its highest diversity in the Andean mountain ranges but also extends into Central America, Africa and Oceania. Although some molecular ...
