Glycome profiling and immunohistochemistry uncover changes in cell walls of Arabidopsis thaliana roots during spaceflight: Advanced Plant EXperiment (APEX) 03-1 Raw Dataset

Based on our previous space flight studies using the Biological Research in Canisters (BRIC) hardware on the STS-131 Space Shuttle mission, we found that plants respond to microgravity in large part through the transcriptional reprogramming of genes that control cell wall remodeling.

This follow-up spaceflight experiment called the Advanced Plant EXperiments (APEX 03-1) in Space was designed to use Veggie unit on the ISS and on the ground unit on the Space Station Processing Facility (SSPF) to probe deeper into spaceflight-induced cell wall associated transcript expression changes. In this study we used RNA-Seq in combination with glycome profiling (glycomics) to correlate spaceflight-induced gene expression changes with actual cell wall modifications within seedlings.
