Dissertation on Arabidopsis and Microgravity is Comprehensive, Powerful

Christina Johnson, a PhD candidate at the Miami University Graduate School has completed her dissertation on Arabidopsis Thaliana grown in microgravity.

Dr. Johnson analyzed data from STS-131 (BRIC-16).  STS-131 was a shuttle launch in April of 2010.  STS-131 has yielded valuable data for astrobotany researchers.  Other papers include Kwon et al., 2015, which examined transcriptional response to spaceflight and revealed interactions with peroxidases and cell wall remodeling.

I can’t possibly do this 198 page dissertation justice by summarizing it (also I’ve only just skimmed it), but I highly recommend it for any spaceflight plant biology researcher.  Dr. Johnson provides insight on genomic changes to A. Thaliana, including actin cytoskeleton rearrangement, cell wall development and stress response.
