Biodiversity of terrestrial algal communities from soil and air-exposed substrates using a molecular approach
(2016-03-08)Terrestrial green microalgae are important primary producers in various habitats like soils, stone (epilithic and endolithic), tree bark and artificial hard substrates. In this thesis, the molecular diversity of green algae ... -
Biodiversity of true lemurs (Eulemur spp.): - Species delimitation and phylogeography in the brown lemur complex
(2013-09-26)Species are the fundamental units of comparison in all subfields of biology. Moreover, species are the currency of biological classification and used to define areas of conservation priority. Hence, central questions of ... -
Biogenesis of respiratory chain: Rcf1 and Rcf2 as a novel assembly factors
(2012-07-04)The mitochondrial respiratory chain consists of four membrane-embedded electron transport complexes (complexes I – IV) and the ATP synthesizing F1F0ATPase. Within the inner mitochondrial membrane these complexes assemble ... -
Bioinformatic analysis of multi-omics data elucidates transcriptional cyclin dependent kinase mediated transcriptional regulation
(2022-08-01)Transcriptional regulation is a highly dynamic biological process which is governed by a complex network of proteins for precise expression of a gene. One of the most important regulators of gene expression are cyclin ... -
Biologische Vielfalt weltweit und regional erhalten - Einflussfaktoren für Handlungsbereitschaften von Schüler(inne)n der Sekundarstufen I und II
(2009-08-19)Although international initiatives already stressed the importance of educational programs as a central role to protect biodiversity (cf. CBD 1992), there is still an urgent need to develop ... -
Biology of odoriferous defensive stink glands of the red flour beetle Tribolium castaneum
(2015-09-15)Chemical warfare is a very common defense strategy in the insect world. A broad range of coleopteran beetles react to predators, invaders, and parasitic microbes with the release of toxic and repellent substances, which ... -
Biophysical characterization and computational modeling of phase separation of immune adapter proteins
(2022-07-07)The processes of B cell activation and development are stimulated by antigen binding to the B cell receptor. Pre-signaling clusters are present in unstimulated, resting B cells and assemble by tripartite phase separation ... -
Biophysical Characterization of SNARE Complex Disassembly Catalyzed by NSF and alphaSNAP
(2008-09-17)SNAREs (SNAP receptors) are small membrane-bound proteins which are key mediators of intracellular membrane fusion. The actual fusion step is believed to occur through complex formation of ... -
Biophysikalische und thermodynamische Charakterisierung der neuronalen SNARE-Komplexbildung
(2008-07-16)Membrane fusion events are mediated by a set of conserved protein machinery, the SNARE proteins. SNARE proteins assemble into a very stable α-helical complex between two membranes. The ... -
Biosynthesis of Aromatic Amino Acids in Yeast and Aspergillus
(2001-02-22)Chorismate mutases (E.C. 5.4.99.5) catalyse the Claisen rearrangement of chorismic acid to prephenate, the first reaction of the tyrosine/phenylalanine-specific branch of aromatic amino acid biosynthesis. Within this ... -
Biotechnological approaches to fight fruit flies of agricultural importance
(2012-10-08)Tephritid fruit flies destroy fruits and vegetables, causing tremendous economic losses and bringing a barrier to trade in fruits, vegetables and their associated products. The Sterile Insect Technique (SIT), a target-specific ... -
Biotoppflege mit Pferden
(2015-04-13)The aim of the research project was to study the vegetation and landscape changes in a grass-dominated nature reserve, under year-round extensive grazing with free-ranging horses. The project area (107 ha) is located at ... -
Blattwasserzustand und Wasserumsatz von vier Buchenwäldern entlang eines Niederschlagsgradienten in Mitteldeutschland
(2003-12-15)1. The aim of the study was to analyze the plasticity of common beech (Fagus sylvatica L.) in water use and the regulation of water balance in adaptation to forest sites with widely differing precipitation regimes. The ... -
Blue light-dependent development of the filamentous fungus Aspergillus nidulans
(2007-11-22)Numerous studies have revealed that fungal development and the production of secondary metabolites are linked although the molecular mechanisms are yet unknown. Light seems to be one of the ... -
Bone Marrow Derived Adult Stem Cells: Characterization and Application in Cell Therapy
(2007-04-25)Due to their high plasticity, ES cells offer a great promise in regenerative medicine; however, the ethical and serious clinical problems limit their application. On the other hand, the ... -
