Dr. John Kiss's research is based on root phototropisims. Generally, roots grow away from light, but based on experiements with Arabidopsis plants the roots grew toward red light but away from blue light. Another reason roots grow downward could be gravity, so Dr. Kiss worked with NASA to perform the experiments with root phototropisim in environments with different levels of gravity using the European Modular Cultivation System (EMCS) in space. I found Dr. Kiss's presentation very informative and interesting. As a NASA enthusiast, I really enjoyed learning about an experiment performed in space making use of microgravity.
