Studies on mountain vegetation, plant diversity, fire and forest line dynamics of the Southeastern and Central Ecuadorian Andes during the Late Quaternary
(2015-02-05)The Ecuadorian Andes in northwestern South America are well known for being among the hot spots of global vascular plant diversity due to their complex topography (uplift of the mountain chain), varying climatic conditions ... -
Studies on the control and function of chromatin fragmentation during apoptosis
(2005-08-10)Apoptosis in eukaryotic cells is often accompanied by chromatin cleavage resulting in nucleosomal fragments. This cleavage is catalyzed by a DNase (named DFF40 or CAD) which is specifically ... -
Studies on the DEAD-box RNA-helicase Dbp5 and the ABC-protein Rli1 in translation termination and identification of a novel function of Dbp5 in ribosomal transport
(2015-09-03)The DEAD-box RNA-helicase Dbp5/Rat8 is well-known for its function in nuclear mRNA export. By using its Gle1 and IP6-stimulated ATPase activity, Dbp5 displaces export factors such as Mex67 from the mRNAs at the cytoplasmic ... -
Studies on vegetation-, fire-, climate- and human history in the mid- to late Holocene - a contribution to protection and management of the forest-steppe-biome in the Mongolian Altai
(2020-09-10)In this thesis, several sedimentological archives from Altai Tavan Bogd National Park are studied to reconstruct the vegetation-, fire-, climate- and human history of the forest-steppe biome in the Mongolian Altai. The ... -
Study of genes of the phytopathogenic fungus Verticillium longisporum involved in the colonization of xylem vessels of its host Brassica napus
(2009-04-22)Verticillium longisporum is a devastating soil - borne fungal pathogen of the rapeseed (Brassica napus). It colonizes the xylem vessels of the host plants but the nutritional status ... -
Study of synaptic vesicle cycling during exo- and endocytosis using optical approaches
(2012-09-25)In the central nervous system, communication between nerve cells mainly occurs at synapses via chemical neurotransmitters. Upon stimulation the transmitters are released by Ca2+-triggered exocytosis of synaptic vesicles ... -
Studying synaptopathies using Mecp2 transgenic mouse models
(2013-09-05)The MECP2 gene is located in the Xq28, which encodes for methyl-CpG binding protein 2 (MeCP2). Mutations in MECP2 gene is the primary cause of postnatal neurodevelopmental disorder, Rett syndrome (RTT) (loss-of-function). ... -
Studying the regulation and development of circadian clock by systems biology approaches
(2020-09-24)System biology approaches, coupled with emerging omics tools, have been widely used and greatly accelerated biological and medical research and discovery. In this thesis, I will focus on applying those tools and technologies ... -
Subcellular and functional analyses of two small heat shock proteins and protein kinases from peroxisomes of Arabidopsis thaliana L.
(2006-08-18)To gain first insights into mechanisms of polypeptide refolding and post-translational regulation of matrix enzymes from plant peroxisomes, the Arabidopsis genome was screened for annotated ... -
Subcellular Localization of Nicotiana tabacum TGA Transcription Factors
(2003-02-11)Salicylic acid (SA) is an important signaling molecule in the regulation of plant defense against pathogens. as-1-like cis-elements in the promoters of many defense genes mediate SA- and ... -
Subcellular trafficking of proteolipid protein (PLP/DM20) and novel mechanisms of ER retention in Pelizaeus-Merzbacher disease
(2006-11-22)Missense mutations that predict the misfolding of membrane proteins have been associated with a number of neurogenetic diseases. However, it is not known how apparently minor changes in the ... -
Submembrane cytoskeleton-regulated assembly and functional activity of gap junctions
(2004-08-23)Connexins form gap junctions that mediate the transfer of ions, metabolites and second messengers between contacting cells. Many connexin functions, e.g cellular transport, plaque assembly ... -
SUMOylierung von NFYA
(2009-02-13)Reversible post-translational modification with SUMO (small ubiquitin-related modifier) is an important mechanism to regulate the function, activity or localization of target proteins. ... -
Die Suszeptibilität der prämeiotischen und meiotischen männlichen Keimzelle zur malignen Transformation
(2001-07-25)Until now it is not known at which specific stage of spermatogenesis the germ cell gets its potency to malignant transformation. In the present thesis the susceptibility of premeiotic and ... -
Symbiotic adaptation of prokaryotic microorganisms in extreme deep-sea environments
(2019-04-10)Extreme deep-sea environments are widespread and intensively studied in the last decades. They are of special interest since living organisms in those habitats happen to live at the expenses of the fluids emitted from the ... -
Synaptic modifications in hippocampal CA3 pyramidal cells in an Alzheimer's mouse model
(2018-03-01)Memory encoding is thought to proceed from durable changes in the activity of synaptic circuits, leading to the storage of patterns of electrical events in a sparsely distributed ensemble of neurons. Located at the entry ... -
Synaptic physiology of the developing <i>Drosophila</i> neuromuscular junction
(2007-04-25)There is a large increase in the number of synapses, and a constant structural and functional remodelling of already established synaptic sites, during the development of both the vertebrate ... -
Synaptic Targeting of Neurotransmitter Receptors is Regulated by Neurobeachin
(2011-11-14)In neuronal network, information is transferred mainly via chemical synapses. Typically, a neuron receives thousands of inputs, which are transmitted by the activation of a large number of ... -
Synaptic vesicle recycling <i>in Vivo</i>
(2012-03-12)The basic mechanism of neurotransmitter release at synapses is relatively well understood: upon arrival of an action potential, calcium influx into the nerve terminal triggers fusion of ... -
Der Syntaxin 1-Cluster - Organisation und Dynamik einer supramolekularen Struktur der Plasmamembran
(2007-06-27)The plasma membrane of a eukaryotic cell shows much more lateral heterogeneity as would be expected according to the fluid mosaic model proposed by Singer and Nicolson in 1972. Many proteins ...
