Phylogeny and evolution of the epiphytic Rhipsalideae (Cactaceae)
(2012-01-11)
Cactaceae are one of the major floristic components of the New World’s arid as well as seasonally moist tropical regions and at the same time one of the most popular plant families in horticulture. The taxonomic units ...
Molekulare Architektur epikutikularer Wachskristalle und die Generierung biomimetischer Oberflächen zur Analyse von Grenzflächeninteraktionen in mikro- und nanoskaligen Dimensionen
(2011)
Die Ziele dieser Arbeit waren die Gewinnung neuer oder die Bestätigung bzw. Widerlegung bekannter Ergebnisse im Forschungsbereich epikutikularer Wachsstrukturen. In drei aufeinander aufbauenden und verknüpften Schwerpunkten ...
Studien zur Aufklärung der Biosynthese apoplastischer Polyester in höheren Pflanzen
(2011-11-15)
Suberinablagerungen in den Wurzeln höherer Pflanzen tragen entscheidend zur Regulation des Wasserhaushaltes bei. Sie ermöglichen der Wurzel eine selektive Aufnahme von Nährstoffen, erlauben den Ausschluss toxischer Substanzen ...
Biogeographical Analyses and Applications: The Study of Plant Distribution Patterns in West Africa
(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 ...
Compost and residues from biogas plant as potting substrates for salt-tolerant and salt-sensitive plants
(2013-01-10)
Compost and residues from biogas plant have been increasingly recognized as potting substrates in horticulture. To investigate the suitability of both materials to grow salt tolerant plants in 2010 a pot experiment was ...
Functional Characterization of Transgenic Arabidopsis thaliana Plants Co-over expressing Aldehyde dehydrogenases and Genes for Soluble Osmolytes
(2010-09-16)
Plant growth and productivity is largely hampered by a number of abiotic stresses. These stresses affect the physiological and metabolic pathways leading to the production of many harmful substances like aldehydes, reactive ...
Spatial patterns of West-African plant diversity along a climatic gradient from coast to Sahel
(2010-07-20)
Understanding species distribution patterns and the corresponding environmental determinants is a crucial step in the development of effective strategies for the conservation and management of plant communities and ecosystems. ...
Genetic Diversity and Population Differentiation Analysis of Ethiopian Barley (Hordeum vulgare L.) Landraces using Morphological Traits and SSR Markers
(2010-06-08)
Morphological and simple sequence repeats (SSR) were used to analyze a total of 199 landraces collected from 10 administrative regions of Ethiopia and four released cultivars of barley. For the morphological data; experiments ......

Trans-Golgi Network as independent organelle from Golgi apparatus in plant cells
(2009-09-14)
In eukaryotic cells, GTPase-Activating Proteins (GAPs) are a family of proteins, which acts on small GTP-binding proteins of the Ras superfamily. GAP proteins have a conserved structure and use similar mechanisms, promoting ...
Dynamics and distribution of ARFB1b and ARFB1c GTPases in N. tabacum plant cells
(2009-09-14)
Eukaryotic cells are characterized by a complex of endomembranes. The main organelles of this complex are the endoplasmic reticulum, the Golgi apparatus, the trans-Golgi network, the vacuoles, and the plasma membrane. In ...
