Many plant species, but also other organisms have developed mechanisms to tolerate such stresses, such as the expression of LEA proteins. Many studies report on physiological protective functions of LEA proteins but lack information about their precise mechanisms on a molecular level. Most LEA proteins are intrinsically disordered in dilute solution but may adopt a distinct secondary structure upon changes in solvent conditions. Understanding the molecular mechanism of how LEA proteins contribute to the counteraction of cellular damage during water-deficits may in the long-term pave the way for breeding crops that are resistant to the effects of global warming. The objective of the work at hand is to improve the biophysical understanding of the sequencestructure-function relationship of LEA proteins as membrane stabilizers, based on the LEA_4 family of the model plant A. thaliana. This is pursued by using a combination of spectroscopic and scattering techniques, supported by bioinformatics and computational analyses. Eight out of the 18 LEA_4 proteins are experimentally assessed revealing that a coil-helix transition in response to water-deficit is a common feature, as predicted for the entire family. In addition, they all stabilize simple membrane models during a freeze/ thaw cycle. Three-dimensional structure prediction of representative members suggests that their completely folded states are represented by a sequential arrangement of alpha-helical segments connected by unstructured linkers, which is experimentally verified for the LEA_4 protein COR15A. The unstructured linker region of COR15A represents a conserved motif among its closest homologs and is, therefore, of particular interest. Facilitating a set of seven designed and investigated COR15A mutants uncovers a complex interplay of transient interactions between the amphipathic alpha-helical segments, mediated by the linker, which fine-tunes folding transitions and structural ensembles upon reduced water-availability. Finally, alpha-helicity is also induced in COR15A upon temperature decrease, which is enhanced in the presence of osmolytes. In addition, high solution osmolarity induced secondary structure is followed by oligomerization of COR15A. Interestingly, the functionality of COR15A, in terms of liposome stabilization, strongly correlates with its alpha-helix ratio in the folded state. The present work significantly improves the understanding of the sequence-structure-function relationship for LEA_4 proteins and offers novel findings on folding mechanisms and oligomerization of COR15A.}, language = {en} } @phdthesis{Eydam2021, author = {Eydam, Ulrich}, title = {Essays on Macroeconomics}, school = {Universit{\"a}t Potsdam}, pages = {161}, year = {2021}, abstract = {This dissertation consists of four self-contained papers. Each paper deals with a specific macroeconomic question. The first paper assesses the distributional implications of environmental policies from a general equilibrium macroeconomic perspective. I develop a New-Keynesian model with several types of uncertainties and frictions that incorporates liquidity constrained households. The model is calibrated to match the German economy and the numerical results show that climate policy instruments can be associated with regressive welfare effects. Furthermore, the analysis shows that these effects can be mitigated through an appropriate revenue recycling scheme. The second paper deals with short-run inequality dynamics within a real business cycle model. An empirical evaluation shows that the cyclical components of income inequality, the capital share and real GDP are correlated. We develop tractable representation of common inequality indicators in the general equilibrium model and show that the observed pattern is driven by innovations in the capital share. A Bayesian estimation of the model for the United States with data for the period 1948 to 2017 indicates that the model provides a reasonable fit for the data and successfully replicates the observed pattern of cyclical correlations. The third paper empirically examines the effects of banking regulation on the risk-relationship between sovereigns and banks. Based on a comprehensive data set of the European banking sector, we find that the implementation of the novel European banking regulation framework significantly contributed to a weakening of the risk-link between sovereigns and banks.The fourth paper empirically examines the role of institutional experience for institutional development in transition economies. To capture institutional experience, we develop a novel index, based on historical country records. The results of cross-sectional and panel estimations suggest that institutional experience helps to explain the divergent economic and institutional development in transition economies after the dissolution of the Soviet Union.}, language = {de} } @phdthesis{Baeseler2021, author = {Baeseler, Jessica}, title = {Trace element effects on longevity and neurodegeneration with focus on C. elegans}, school = {Universit{\"a}t Potsdam}, pages = {X,114,VIII}, year = {2021}, abstract = {The trace elements zinc and manganese are essential for human health, especially due to their enzymatic and protein stabilizing functions. If these elements are ingested in amounts exceeding the requirements, regulatory processes for maintaining their physiological concentrations (homeostasis) can be disturbed. Those homeostatic dysregulations can cause severe health effects including the emergence of neurodegenerative disorders such as Parkinson's disease (PD). The concentrations of essential trace elements also change during the aging process. However, the relations of cause and consequence between increased manganese and zinc uptake and its influence on the aging process and the emergence of the aging-associated PD are still rarely understood. This doctoral thesis therefore aimed to investigate the influence of a nutritive zinc and/or manganese oversupply on the metal homeostasis during the aging process. For that, the model organism Caenorhabditis elegans (C. elegans) was applied. This nematode suits well as an aging and PD model due to properties such as its short life cycle and its completely sequenced, genetically amenable genome. Different protocols for the propagation of zinc- and/or manganese-supplemented young, middle-aged and aged C. elegans were established. Therefore, wildtypes, as well as genetically modified worm strains modeling inheritable forms of parkinsonism were applied. To identify homeostatic and neurological alterations, the nematodes were investigated with different methods including the analysis of total metal contents via inductively-coupled plasma tandem mass spectrometry, a specific probe-based method for quantifying labile zinc, survival assays, gene expression analysis as well as fluorescence microscopy for the identification and quantification of dopaminergic neurodegeneration.. During aging, the levels of iron, as well as zinc and manganese increased.. Furthermore, the simultaneous oversupply with zinc and manganese increased the total zinc and manganese contents to a higher extend than the single metal supplementation. In this relation the C. elegans metallothionein 1 (MTL-1) was identified as an important regulator of metal homeostasis. The total zinc content and the concentration of labile zinc were age-dependently, but differently regulated. This elucidates the importance of distinguishing these parameters as two independent biomarkers for the zinc status. Not the metal oversupply, but aging increased the levels of dopaminergic neurodegeneration. Additionally, nearly all these results yielded differences in the aging-dependent regulation of trace element homeostasis between wildtypes and PD models. This confirms that an increased zinc and manganese intake can influence the aging process as well as parkinsonism by altering homeostasis although the underlying mechanisms need to be clarified in further studies.}, language = {en} } @phdthesis{HeywoodJones2021, author = {Heywood Jones, David}, title = {Moses Hirschel and Enlightenment Breslau}, publisher = {Palgrave Macmillan}, address = {Cham}, isbn = {978-3-030-46234-5}, doi = {10.1007/978-3-030-46235-2}, pages = {viii, 264}, year = {2021}, abstract = {Breslau has been almost entirely forgotten in the Anglophone sphere as a place of Enlightenment.

In contrast to what is observed in our solar system, where gaseous planets orbit at wide orbits, Jupiter type exoplanets were detected in foreign stellar systems surrounding their host stars within few days, in close orbits, the so called hot- and ultra-hot Jupiters. The most well studied ones are HD209458b and HD189733b, which are the first exoplanets where absorption is detected in their atmospheres, namely from the alkali line sodium. For hot Jupiters, the resonant alkali lines are the atmospheric species with one of the strongest absorption signatures, due to their large absorption cross-section. However, al- though the alkali lines sodium and potassium were detected in low-resolution observations for various giant exoplanets, potassium was absent in different high-resolution investiga- tions in contrast to sodium. The reason for this is quite puzzling, since both alkalis have very similar physical and chemical properties (e.g. condensation and ionization proper- ties). Obtaining high-resolution transit observations of HD189733b and HD209458b, we were able to detect potassium on HD189733b (Manuscript 1), which was the first high-resolution detection of potassium on an exoplanet. The absence of potassium on HD209458b could be reasoned by depletion processes, such as condensation or photo-ionization or high-altitude clouds. In a further study (Manuscript II), we resolved the potassium line and compared this to a previously detected sodium absorption on this planet. The comparison showed, that the potassium lines are either tracing different altitudes and temperatures compared to the sodium lines, or are depleted so that the planetary Na/K- ratio is way larger than the stellar one. A comparison of the alkali lines with synthetic line profiles showed that the sodium lines were much broader than the potassium lines, probably being induced by winds. To investigate this, the effect of zonal streaming winds on the sodium lines on Jupiter-type planets is investigated in a further study (Manuscript III), showing that such winds can significantly broaden the Na- lines and that high-resolution observations can trace such winds with different properties. Furthermore, investigating the Na-line observations for different exoplanets, I showed that the Na-line broadening follows a trend with cooler planets showing stronger line broadening and so hinting on stronger winds, matching well into theoretical predictions. Each presented manuscript depends on the re- sults published within the previous manuscript, yielding a unitary study of the exoplanet HD189733b. The investigation of the potassium absorption required to account for different effects: The telluric lines removal and the effect of center-to-limb variation (see Manuscript I), the residual Rossiter-Mc-Laughlin effect (see Manuscript II) and the broadening of spectral lines on a translucent atmospheric ring by zonal jet streams (see Manuscript III). This thesis shows that high-resolution transmission spectroscopy is a powerful tool to probe sharp alkali line absorption on giant exoplanet atmospheres and to investigate on the properties and dynamics of hot Jupiter type atmospheres.}, language = {en} } @phdthesis{Bebnowski2021, author = {Bebnowski, David}, title = {K{\"a}mpfe mit Marx}, series = {Geschichte der Gegenwart}, journal = {Geschichte der Gegenwart}, number = {25}, publisher = {Wallstein}, address = {G{\"o}ttingen}, isbn = {978-3-8353-5031-1}, school = {Universit{\"a}t Potsdam}, pages = {534}, year = {2021}, abstract = {Die Wiederentdeckung des Marxismus durch die Neue Linke: eine spannungsvolle Geschichte.Schon vor 1968, in den 1950er Jahren, entstand eine Neue Linke.
