Plants use a myriad of environmental cues to inform their growth and development. The force of gravity has been a consistent abiotic input throughout plant evolution, and plants utilize gravity sensing mechanisms to maintain proper orientation and architecture. Despite thorough study, the specific mechanics behind plant gravity perception remain largely undefined or unproven. At the center of plant gravitropism are dense, specialized organelles called starch statoliths that sediment in the direction of gravity. Herein I describe a series of experiments in Arabidopsis that leveraged RNA sequencing to probe gravity response mechanisms in plants, utilizing reorientation in Earth's 1g, fractional gravity environments aboard the International Space Station, and simulated fractional and hyper gravity environments within various specialized hardware. Seedlings were examined at organ-level resolution, and the statolith-deficient pgm-1 mutant was subjected to all treatments alongside wildtype seedlings in an effort to resolve the impact of starch statoliths on gravity response. In all, 132 unique genotype/tissue/treatment datasets were collected to help further our understanding of the gravitropic mechanisms in plants.
