Plant Gravitational and Space Biology

Abstract

Being sessile, plants avoid or mitigate various stresses by controlling their growth and development in response to environmental stimuli such as gravity, light, water, and touch. For example, plants display gravitropism to grow their shoots upward and roots downward. The gravitropic responses play important roles in plant survival and productivity by obtaining light, carbon dioxide, water, and nutrients for photosynthesis and growth.

I have studied plant responses to gravity and their influences on other growth phenomena by conducting both ground-based and spaceflight experiments. These studies revealed unique regulatory mechanisms for plant gravimorphogenesis controlled by a plant hormone, auxin, and gravity-influenced growth phenomena like hydrotropism in roots. Based on the knowledge obtained to date, I am currently studying plant responses to the space environment and genetic traits useful for plant cultivation in space, aiming at supplying foods for the long-term stay of human beings in space.
