Untersuchungen zum anatomischen, physiologischen und molekularbiologischen Abwehrverhalten an gesunden und geschädigten Buchen (Fagus sylvatica L.) mit der Symptomatik „Buchenkomplexkrankheit”
(2006-12-13)One of the most important disease of European Beech trees (Fagus sylvatica L.) is called Beech Bark Disease which was first described by ROBERT HARTIG in 1878. The European Beech ... -
Untersuchungen zum Fettsäuretransport durch zelluläre und peroxisomale Membranen
(2010-11-12)Despite intensive research and numerous publications the precise mechanism by which free fatty acids cross the plasma membrane is still controversial. Within this work we addressed the ... -
Untersuchungen zum Mechanismus der katalytischen Aktivierung von Spleißosomen aus Saccharomyces Cerevisiae
(2013-02-13)Pre-mRNA splicing is catalyzed by the spliceosome, a multimegadalton ribonucleoprotein (RNP) complex. It assembles anew on each pre-mRNA intron by the stepwise binding of five snRNPs (U1, U2, U4, U5 and U6) and numerous ... -
Untersuchungen zur antiangiogenen Aktivität des matrizellulären Proteins Thrombospondin-2
(2008-07-21)The formation of new tumor vessels (tumorangiogenesis) is an important mechanism for the growth and progression of tumors. Tumorangiogenesis depends on a complex interplay between pro-and ... -
Untersuchungen zur Bedeutung der sal-ähnlichen Gene bei der Maus
(2002-01-11)The region-specific homeeotic gene spalt (sal) of Drosophila melanogaster is required for the specification of larval posterior head and anterior tail structures during embryogenesis. ... -
Untersuchungen zur Dynamik des Nährstofftransports im Xylem von Pappeln unter besonderer Berücksichtigung der Stickstoffversorgung des Sprosses
(2001-10-02)Long-distance transport of nutrients from root to shoot occurs in the xylem. The aim of this study was to characterise the nutrient transport in the xylem of young poplar. The transport of ... -
Untersuchungen zur Expression, Funktion und Regulation ausgewählter Gene der Insulinfamilie
(2006-10-16)In the present study, expression and functional analyses of two novel members of the insulin-superfamily, Insl5 and Insl6, were performed. Northern blot analysis on mRNA extracted from the ... -
Untersuchungen zur Funktion des basischen Helix-Loop-Helix (bHLH)-Transkriptionsfaktors ME2 bei Lern- und Gedächtnisprozessen in der Maus
(2009-08-20)ME2 (Tcf4) belongs to the basic helix-loop-helix (bHLH) transcription factor family, activates transcription of target genes by binding to so-called E-boxes elements and its mRNA expression ... -
Untersuchungen zur Funktion des RanGAP1 Proteins
(2007-08-07)Beyond its main function in nucleocytoplasmic transport the RanGTPase cycle has been implicated in the regulation of various aspects of mitotic progression. The RanGTPase activating protein ... -
Untersuchungen zur genetischen Regulation der CO<sub>2</sub>-Assimilation in <i>Ralstonia</i> spp.
(2006-05-02)Autotrophic CO2 assimilation in Ralstonia eutropha H16 and Ralstonia metallidurans CH34 involves the enzymes of the Calvin-Benson-Bassham (CBB) cycle. The expression of the two ... -
Untersuchungen zur Inaktivierung und Reaktivierung der Coenzym B12-abhaengigen Glycerin-Dehydratasen aus Citrobacter freundii und Clostridium pasteurianum
(2002-01-11)The coenzyme B12-dependent glycerol dehydratase of Citrobacter freundii is subject to suicide inactivation by the natural substrate glycerol during catalysis. We identified dhaF and dhaG ... -
Untersuchungen zur Inhibierung der Expression der Poly(ADP-ribose)Polymerase (PARP) nach Infektion mit Toxoplasma gondii
(2008-11-17)Toxoplasma gondii is a world wide spread and obligate intracellular protozoan parasite, which induces mostly asymptomatic, lifelong persisting infections in humans. Furthermore, it is an ... -
Untersuchungen zur Physiologie des Essigsäurebakteriums Gluconobacter oxydans 621H
(2006-08-22)Gluconobacter oxydans 621H is a Gram-negative alpha-proteobacterium that belongs to the family Acetobacteriaceae. This strictly aerobic organism is adapted to growth in substrate-rich ... -
Untersuchungen zur Regulation des Insl3 Gens
(2003-02-05)Insl3 is a testisspecific hormone which governs the development of the gubernaculum ligament needed for the migration of the embryonal testis to its adult scrotal position. We ... -
Untersuchungen zur Rolle des <i>MPH1</i>-Gens aus <i>Saccharomyces cerevisiae</i> bei der Reinitiation der Replikation nach schadensinduzierten Arresten
(2003-12-10)For the error-free removal of DNA damages the damaged bases are usually removed by mechanisms like nucleotide or base excision repair (NER, BER), mismatch repair etc. and the resulting gap ... -
Untersuchungen zur Rolle von Mph1 aus Saccharomyces cerevisiae und seines menschlichen Orthologen FANCM bei der Erhaltung der genomischen Integrität
(2022-07-22)Living is life-threatening. Cells can only endure the diverse exogenous and endogenous attacks on their genome because they are equipped with a network of coordinated security measures: the DNA damage response. Repair ... -
Untying Gordian knots: The evolution and biogeography of the large European apomictic polyploid Ranunculus auricomus plant complex
(2021-10-19)Polyploidy, the presence of two or more full genomic complements, repeatedly occurs across the tree of life. In plants, not only the economic but particularly the evolutionary importance is overwhelming. Polyploidization ... -
