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 ...
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 ......
Autophagy and Vesicle Trafficking in Arabidopsis: Emerging Roles of Gamma Secretase Complex Subunits and AP4 Complex
(2020-02-17)
Presenilins are the catalytic component of γ-secretase complex which was first identified in the genetic screens of the patients suffering from the Alzheimer's disease. Macroautophagy is a major route which encompasses ......
Constraint-based automated reconstruction of grape bunches from 3D range data for high-throughput phenotyping
(2019-10-25)
With increasing global population, the resources for agriculture required to feed the growing number of people are becoming scarce. Estimates expect that by 2050, 60 % more food will be necessary. Nowadays, 70 % of fresh ...
