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. ...
Quantitative Bestimmung der Permeabilität und Analyse der chemischen Zusammensetzung ausgewählter Kutikula-Mutanten von Arabidopsis thaliana
(2010-12-22)
Die Kutikula bildet die Grenzfläche zwischen den oberirdischen Pflanzenorganen und der Umwelt. Für viele Spezies (z.B. P. laurocerasus) wurden bereits transportphysiologische Untersuchungen mit isolierten Kutikularmembranen ...
Gravity-sensing processes and gravity-dependent gene expression in plants: studied under altered gravity conditions
(2010-11-05)
The present study focused on the cellular and molecular gravisensing-related processes in Arabidopsis and in the unicellular rhizoids of the green alga Chara. Experiments during sounding-rocket and parabolic plane flights ...
Gewebsspezifische Expression von Mitogen-aktivierten Proteinkinasen und Signalübertragung an das Mikrotubuli- Zytoskelett in Arabidopsis thaliana
(2010-01-04)
In dieser Arbeit sind drei MAPK aus A. thaliana näher charakterisiert wurden. Wie bereits bekannt ist, sind MPK3, MPK4 und MPK6 an vielen abiotischen und biotischen, sowie entwicklungsspezifischen Signalwegen beteiligt. ...
Comparative and functional promoter analysis of desiccation-related genes from three closely related plant species differing in desiccation tolerance
(2010-03-23)
The closely related resurrection plants C. plantagineum and L. brevidens have the rare ability to withstand desiccation of their vegetative tissues. The species L. subracemosa is a close relative of C. plantagineum and L. ...
Exploring non-coding mitochondrial DNA sequences in bryophyte molecular evolution
(2010-04-28)
The thesis presented here focussed on the molecular evolution of non-coding mitochondrial DNA in liverworts and mosses.
To address remaining questions in moss phylogeny, three mitochondrial gene regions were investigated ......

Phosphoproteomic Analysis of Craterostigma plantagineum upon Abscisic Acid and Desiccation Stress
(2010-04-20)
Studies aimed at understanding the molecular basis of the desiccation tolerance in angiosperms have mainly focused on the South African plant Craterostigma plantagineum. C. plantagineum belongs to the Linderniaceae family, ...
Evolution and Diversification of the Hookeriales (Bryopsida) with emphasis on Distichophyllum (Daltoniaceae) and its allied genera
(2010-04-01)
Unbiased by human intuition in interpreting morphological criteria and by convergence of morphological traits, recent methods in molecular phylogeny is offering an independent option to guide our postulations on phylogeny. ......
Superhydrophobe Oberflächen: Funktionserhaltung durch Regeneration
(2010-03-03)
Viele pflanzliche Oberflächen weisen eine räumliche Mikrostrukturierung auf. Diese Mikrostrukturen sind häufig zusätzlich mit hydrophoben Wachsstrukturen bedeckt. Aufgrund dieser hierarchischen Strukturierung und der Chemie ...
