2-D clinorotation alters the uptake of some nutrients in Arabidopsis thaliana.

Future long-term spaceflight missions rely on bioregenerative life support systems (BLSS) in order to provide the required resources for crew survival. Higher plants provide an essential part since they supply food and oxygen and recycle carbon dioxide. There are indications that under space conditions plants might be inefficient regarding the uptake, transport and distribution of nutrients, which in turn affects growth and metabolism.

Actin, actin-related proteins and profilin in diatoms: a comparative genomic analysis.

Diatoms are heterokont unicellular algae with a widespread distribution throughout all aquatic habitats. Research on diatoms has advanced significantly over the last decade due to available genetic transformation methods and publicly available genome databases. Yet up to now, proteins involved in the regulation of the cytoskeleton in diatoms are largely unknown.
