ABA-Dependent and -Independent Regulation of Tocopherol (Vitamin E) Biosynthesis in Response to Abiotic Stress in Arabidopsis
Kreszies, Victoria (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 ... -
Air layers under water on the fern Salvinia: Stability and biomimetic applications
Mayser, Matthias (2014-05-27)Many plants and animals feature superhydrophobic surfaces capable of retaining a layer of air when submerged under water. The most persistent air layers can last for weeks and even month and are maintained by hairy surfaces ... -
Aluminum Stress on Suberin Biosynthesis in Barley (Hordeum vulgare) Roots
Meng, Hongjun (2023-08-29)Aluminum (Al) toxicity is a major factor inhibiting plant growth in acidic soils worldwide, and the root barrier formed by suberized cells is an important mechanism for plants to resist environmental stress. The aim of ... -
Amyloid β-peptide-induced progressive neurodegeneration in an APP-transgenic mouse model for Alzheimer’s disease
Capetillo Gonzalez de Zarate, Estibaliz (2006)The amyloid beta-protein (Abeta) is the main component of Alzheimer's disease (AD)-related senile plaques. In the human brain Abeta-deposition occurs in a hierarchical sequence in which different areas of the brain become ... -
Analyse der Wurzelarchitektur von Gerste (Hordeum vulgare) unter verschiedenen Umweltbedingungen
Schaprian, Tamara (2015-05-11)Innerhalb der letzten Jahre zeigte der Aufruf zu einer "second green revolution" die Notwendigkeit zur Entwicklung leistungsfähiger Kulturpflanzen mit robustem Verhalten auf wechselnde Umweltbedingungen und limitierte ... -
Analysis of the AtMRS2 magnesium transporter family in Arabidopsis thaliana via gene-GFP fusions, heterologous complementations, and protein interaction studies
Weyand, Katrin (2007)Magnesium is unique in its chemical properties compared to the other biologically relevant cations. It plays an important role in many biological functions, e.g. as a cofactor for numerous enzymes, as the central atom of ... -
Analytik von ozoninduzierten phenolischen Sekundärmetaboliten in Nicotiana tabacum L. cv Bel W3 mittels LC-MS
Koch, Imke (2008)In der vorliegenden Arbeit wurde untersucht, welche löslichen, phenolischen Sekundärmetabolite unter einem akuten Ozonstress verstärkt oder neu in der ozonsensitiven Tabakvarietät Nicotiana tabacum L. cv Bel W3 ... -
Applikation des Chloroplasten-Thylakoid-Biosensors auf nitroaromatische Verbindungen am Beispiel von Rüstungsaltlasten
Schulz, Oliver (2006)Für die menschliche Gesundheit bedeutet eine Exposition zu nitroaromatischen Verbindungen ein hohes Risiko, da bereits deutliche Gefährdungen für aquatische und terrestrische Systeme, inklusive Säugern, festgestellt werden ... -
Aufreinigung und Charakterisierung des D1-Proteins aus dem Photosystem II höherer Pflanzen: Entwicklung eines Biosensors auf der Basis der Oberflächen-Plasmon-Resonanz-Technologie
Schulten, Carmen (2006)Rückstände von Pflanzenschutzmitteln (Pestizide), insbesondere von Herbiziden, stellen eine immer weiter zunehmende Gefährdung für den Menschen und die Ökosysteme dar. Zum Schutz der menschlichen Gesundheit und der Umwelt ... -
Autophagy and Vesicle Trafficking in Arabidopsis: Emerging Roles of Gamma Secretase Complex Subunits and AP4 Complex
Hassan, Ammar (2020-02-17)Presenilins are the catalytic component of γ-secretase complex which was first identified in the genetic screens of the patients suffering from the Alzheimer's disease. Macroautophagy is a major route which encompasses ... -
Biodiversität und Erhalt der Hochlagenvegetation der Insel Fogo (Kap Verde): Ausarbeitung eines Konzeptes für ein Schutzgebiet
Leyens, Teresa (2003)The presented PhD thesis „Biodiversity and Conservation of the Vegetation of the High Altitudes of the Island of Fogo (Cape Verde): Elaboration of a Concept for a Protected Area“ was elaborated within the bounds of a grant ... -
Biogeographical Analyses and Applications: The Study of Plant Distribution Patterns in West Africa
García Márquez, Jaime Ricardo (2011-03-10)Studies and applications in biogeography aim at understanding the causes and determinants of past, current, and future diversity distribution patterns. In this context, niche models are currently important tools. They make ... -
Biogeomorphic dynamics in the Turtmann glacier forefield, Switzerland
Eichel, Jana (2017-05-19)Worldwide, glacier retreat enlarges glacier foreland areas, which are characterized by pronounced geomorphic and ecologic dynamics. Feedbacks between these dynamics are believed to drive glacier foreland landscape development, ... -
