Climate- and Human-Induced Vegetation Changes in Northwestern Turkey and the Southern Levant since the Last Glacial
(2017-04-20)
Northwestern Turkey and the southern Levant are key regions for studying vegetation and climate developments during migration phases of modern humans and the origin and expansion of agriculture. Both regions have a long ...
Physiological and molecular studies of different aldehyde dehydrogenase (ALDH) genes in response to high temperature and functional analyses of the ALDH7B4 promoter in Arabidopsis thaliana
(2017-04-06)
In this study, the function of aldehyde dehydrogenase (ALDH) genes in response to heat stress alone and in combination with dehydration, salinity, or wounding stress was investigated using selected ALDH genes ...
Biogeomorphic dynamics in the Turtmann glacier forefield, Switzerland
(2017-05-19)
Worldwide, glacier retreat enlarges glacier foreland areas, which are characterized by pronounced geomorphic and ecologic dynamics. Feedbacks between these dynamics are believed to drive glacier foreland landscape development, ...
Systematics, Taxonomy, and Evolution of Urtica L. (Urticaceae)
(2017-04-25)
The systematics of Urtica have puzzled scientists for the past 200 years and no single comprehensive attempt at understanding infrageneric relationships has been published in the past, nor have species delimitations ...
Evaluating the phylogenetic structure and microstructural evolution of organellar markers from both compartments in the reconstruction of a carboniferous radiation (mosses)
(2017-09-12)
In the reconstruction of the plant tree of life, sequence data from the plastid genome is currently favored as it contains a mixture of coding and noncoding regions, spanning different patterns of substitution rates and ...
Interaction of surfactants with leaf surfaces: Analysis of time-dependent changes in leaf surface wetting, foliar uptake of surfactants and surfactant-induced transcriptomic changes in barley leaves
(2022-08-31)
Since a long time it is well known, that the cuticle covering above ground primary plant organs and provides a barrier against uncontrolled water loss between the plant and the atmosphere. In plant protection one of the ......
The chloroplast calcium sensor protein CAS is part of the STN7/STN8 kinase phosphorylation network and is required for photoacclimation
(2020-03-10)
In the present work, the phosphorylation profile of the chloroplast-localized Calcium Sensing Receptor (CAS) from A. thaliana was investigated and it could be shown that CAS is a target of multiple protein kinases acting ......
Untersuchungen zu Biotensid produzierenden epiphyllen Pseudomonaden
(2019-10-16)
Die Phyllosphäre umfasst den gesamten Lebensraum auf Blattoberflächen und bildet eine der größten ökologischen Nischen für mikrobielles Leben auf organischen Oberflächen. Zu den häufigsten Bewohnern der Phyllosphäre gehören ......
Evolution of floral organisation and architecture in Boraginales and Geraniales
(2020-08-13)
In this thesis, development, morphology and anatomy of structures from selected taxa from the Gera- niales and Boraginales are studied. Furthermore, the integration of structures such as stamen-corolla tube modifications ......
Molecular and biochemical studies of the Craterostigma plantagineum cell wall during dehydration and rehydration
(2020-02-17)
Craterostigma plantagineum belongs to the desiccation tolerant angiosperm plants. Upon dehydration leaves fold and the cells shrink which is reversed during rehydration. To understand this process changes in cell wall ......
