Microgravity alters plant transcriptional networks via coordinated gene set regulation
Explains the reasoning connecting microgravity exposure to the observed pattern of upregulation of auxin, vesicle-mediated transport, and gravitropism-related genes, and concurrent downregulation of stress response and chloroplast/photosynthesis related genes, as indicated by RNA-Seq analyses in two independent spaceflight experiments using on-orbit 1g controls. Highlights the coherence and specificity of the transcriptional reprogramming attributed to microgravity, distinct from other spaceflight-associated factors, and rationalizes key shifts in HY5 target gene regulation and miRNA-mediated modulation.
