Astronauts in low-earth orbit could use a fresh salad to brighten up all those freeze-dried meals. But the microgravity space environment can affect plant growth in ways we’re only beginning to understand. In research presented in a recent issue of Applications in Plant Sciences, Drs. Anna-Lisa Paul and Robert Ferl, and colleagues at the University of Florida Space Plants Lab, showed that two different transcriptomic approaches could feasibly be used to understand how subcomponents of plant organs respond to the space environment.
