Plant Ribonucleic Acid (RNA) Regulation Harvest

iss049e008853 (9/23/2016) --- NASA astronaut Kate Rubins is photographed performing the second harvest of the Plant RNA Regulation experiment by removing the European Modular Cultivation System (EMCS) Seed Cassettes from EMCS Rotors A and B stowing them in an EMCS Cold Stowage Pouch. The Plant RNA Regulation investigation studies the first steps of gene expression involved in development of roots and shoots. Scientists expect to find new molecules that play a role in how plants adapt and respond to the microgravity environment of space, which provides new insight into growing plants for food and oxygen supplies on long-duration missions.
