ARABIDOMICS- Integration of alterations on transcript, protein and metabolite level of Arabidopsis thaliana exposed to simulated microgravity

Abstract

The requirement for plants as food and oxygen sources during prolonged manned space travels caused an increased interest in the identification of genes involved in plant-adaptation to microgravity. Transcriptomic, proteomic and metabolomic techniques provide a sensitive high-throughput approach to identify regulations in response to changes of the gravitational force. The ARABIDOMICS project generated and correlated omics data (on the transcript, protein and metabolite level) that support the assumption that simulated microgravity has a strong impact on plant cell wall biosynthesis and structure, phytohormone biosynthesis and signaling, generation of toxic compounds (reactive oxygen species), secondary metabolite biosynthesis and cytoskeleton organisation in Arabidopsis thaliana roots.
