We recently received a space flight certificate for the Arabidopsis plants launched in to space as a part of a project to understand responses to simulated space radiation. This study compared the similarities and differences in Arabidopsis's response(s) to simulated GCR and SPE exposure at different developmental stages, i.e. seeds vs. 10-day old seedlings. KEGG pathway analysis for DEGs showed enrichment of pathways associated with base excision repair, mismatch repair, DNA replication, homologous recombination, non-homologous end-joining and RNA polymerase activity in 10-day old seedlings and seeds irradiated wand grown after simulated GCR exposure.
Data analysis and interpretation efforts for GCR/SPE exposed mizuna and tomato seeds is ongoing.
