Aminosäuretransport in Raps unter besonderer Berücksichtigung des Entwicklungsstadiums der Pflanze und der Stickstoffdüngung
(2003-11-18)Oilseed rape (Brassica napus L.) is the most important oil crop plant in Europe. Despite a very efficient uptake of nitrogen (N) from the soil, oilseed rape has a low nitrogen use ... -
Änderung der Glycindecarboxylase- und Serinhydroxymethyltransferase-Aktivität in Blättern:
(2005-09-28)In C3/C4-intermediate plant species, photorespiration is avoided by compartmentation of CO2 evolution and glycine production in the bundle sheath of the leaves. This CO2 concentration ... -
Carbon partitioning in nitrogen-fixing root nodules
(2003-02-28)Nitrogen-fixing root nodules represent strong carbon sinks. Sugar partitioning was studied in three different symbiotic systems, namely a legume, Medicago truncatula, and two actinorhizal ... -
Cloning and characterization of organic anion systems in the adrenal cortex and their role in steroid release
(2001-06-06)The adrenal steroid hormones have a central role in maintaining homeostasis, as they have influence on almost every physiological process. Their movement across the cell membrane is still ... -
I. Etablierung eines induzierbaren Suizidsystems zur Identifizierung von Mutanten der salizylsäureabhängigen Signaltransduktion II. Expression von tierischen Signaltransduktionskomponenten in Tabak zur Herstellung eines induzierbaren Expressionssystems
(2002-09-04)During pathogen defense in plants the salicylic acid concentration increases. In response to this signal a number of defense genes is activated via a signal transduction chain few steps of ... -
Isolierung und Charakterisierung der gamma-Tocopherolmeth yltransferase
(2001-12-18)The tocopherols and tocotrienols are well known antioxidants and play an important role in protecting cells from free radical damage and in the prevention of many diseases, e.g. cancer and ... -
Mechanisms of proton translocation in Methanosarcina mazei Gö1
(2001-12-19)Methanogenesis from methanol and H2 plus CO2 is coupled to the generation of a transmembrane ion gradient, which is the driving force for ATP formation from ADP plus Pi.In this work three ... -
Nachweis und Aufreinigung von Abscisinsäure-bindenden Proteinen aus dem Cytosol von Spinat- und Arabidopsis-Pflanzen
(2003-01-09)Goal of this work was to isolate abscisic acid binding proteins of spinach and Arabidopsis plants. Therefore the use of different proteinbiochemic methods like ammoniumsulfate-precipitation ... -
On the role of sugar compartmentation and stachyose synthesis in symplastic phloem loading
(2002-03-08)Compartmentation of phloem-translocated carbohydrates and localization of the synthesis of one specific transport form, stachyose, was studied in leaves of symplastic phloem loaders. In ... -
Proteome studies on leaf peroxisomes from Spinacia oleracea L. and Arabidopsis thaliana (L.) Heynh.
(2004-05-26)A proteome analysis of leaf peroxisomes was initiated to further increase our understanding of the functions of this ubiquitous eukaryotic subcellular entity. A reported method for the ... -
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 ... -
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 ... -
Zur Bedeutung von Saccharose-Transportern in Pflanzen mit offener Phloemanatomie
(2001-12-04)Plants translocate photoassimilates, e.g. sucrose, through a specialized transport tissue called phloem. This long distance transport between different parts of the plant is essential for ...
