Molecular analysis of the plastid-targeted gene and protein (CpPTP-1) associated with desiccation tolerance in the resurrection plant Craterostigma plantagineum
(2021-01-28)
Water scarcity causes drought stress and enormous losses in agricultural production, and consequently this leads to a worldwide food crisis. Craterostigma plantagineumis one of the best studied resurrection plants that is ......
Die konvergente Totalsynthese von Ajudazol A über Oxazolmodifikationen
(2020-07-14)
In der vorliegenden Dissertation wird die erste Totalsynthese von Ajudazol A, einem Vertreter der Naturstofffamilie der Ajudazole, beschrieben. Da diese zu den Polyketiden gehörende Naturstoffklasse selektiv die mitochondriale ...
Characterization of the Sulfite-Generating rDsrABL Complex of Allochromatium vinosum
(2020-12-16)
Microbial pathways of sulfur dissimilation have strongly contributed to the evolution of the biogeochemical sulfur cycle and still play a major role in it today. Dissimilatory sulfite reductases, which occur in both sulfate ......
Functional Integration of Floral Plant Traits: Shape and Symmetry, Optical Signal, Reward and Reproduction in the Angiosperm Flower
(2020-05-12)
Pollination syndromes represent groups of floral phenotypes that have originated and diversified in interaction with biotic and abiotic pollen vectors. Plant trait pattern that constitute respective syndromes have been ...
Underwater flight in sea turtles and plesiosaurs: Dissection, muscle reconstructions, analog models, and finite element structure analyses inform on flipper twisting and muscle forces in plesiosaurs
(2020-08-13)
This dissertation contributes to our understanding of plesiosaur locomotion by providing foreflipper and hindflipper muscle reconstructions and studying aspects of their muscle physiology (functions, forces, muscle length ......
The Role of TRIM71 in Male Germ Cell Development
(2020-09-02)
Germ cells are the key to continuation of life as they are the unique cell lineage capable to transfer the complete genetic information to the next generation. Both, infertility and testicular cancers are usually originating ......
Simultaneous identification of nucleotide-modified aptamers with different properties by multiplexed click-SELEX
(2020-06-18)
Voltage-gated sodium channels (VGSC) are important key regulators in excitable tissue that initiate and propagate the action potential in specifically excitable tissue such as brain nerves or muscle. In order to understand ...
Design & generation of an efficient E. coli cell-factory for the overproduction of the compatible solutes ectoine & hydroxyectoine
(2020-07-01)
The compatible solutes ectoine and hydroxyectoine are produced by halophilic or halotolerant bacteria in order to balance and adapt to osmotic alterations in their habitat. Besides this, the potent ability of these compounds ...
Analyse von periplasmatischen Schwefeltransferasen aus Allochromatium vinosum
(2021-07-19)
Die ersten Schritte der Schwefeloxidation in Allochromatium vinosum finden im Periplasma statt, wo reduzierte Schwefelverbindungen oxidiert und in diesem Zuge Schwefelkugeln aufgebaut werden. Es ist denkbar, dass ...
Loss of Inhibitory CD33 Signaling Results in Increased Microglial Activation
(2021-06-23)
CD33 is expressed on immune cells of myeloid origin, such as macrophages and microglia. Upon activation, CD33 recruits and activates protein tyrosine phosphatases, which results in attenuation of the activatory signaling ...
