In the long term, it is aimed to modify plants by breeding or genetic engineering in a way that they can germinate, grow and reproduce under space conditions as optimal as possible, because they play an important role for the nutrition and the psychological well-being of humans and in the frame of bioregenerative life support systems.mehr...
Die Gravitation ist der einzig konstante Reiz, der während der Evolution die Entwicklung des Lebens, so wie wir es kennen, beeinflusst hat. Die Wahrnehmung der Schwerkraft ist für lebende Organismen elementar für die Orientierung im Raum. Vom Einzeller bis zum Menschen entwickelten sich verschiedene Strategien, Zellen sowie Organe, um die Richtung der Erdanziehung zu perzipieren und physiologisch zu verarbeiten.mehr...
By this project we want to further contribute to the understanding of the mechanisms of gravity perception, signaling and adaptation in plants. It is already known that posttranslational modifications (phosphorylation etc.) of proteins are essential for a fast initial response to changes of the environment, which in turn activate or deactivate proteins before the de novo protein biosynthesis starts.mehr...
The alga Euglena gracilis and the moss Physcomitrella patens are both highly sensitive in the perception of gravity (g). The stationary moss Physcomitrella patens shows a negative gravitropism of the protonemata while the mobile Euglena gracilis displays a negative gravitaxis and additionally phototaxis to reach optimal growth conditions in the water column.mehr...
These experiment campaigns, carried out by the Institut für Zoologie of the university of Hohenheim in Stuttgart, investigate the behaviour of fish under microgravity conditions.mehr...
The aim of the study is to investigate the effects of micro and hyper gravity on the activity of artificial and native ion channels as well in artificial lipid membranes as in living cells.mehr...
The University of Bonn were able to detect for the first time extreme early signals in roots of Zea mays which are triggered by microgravity.mehr...
