Abstract:
The study of gravitropism dates back about two hundred years, and although significant progress has been made in this field, the central question in gravitropism research is still unanswered. How is a physical stimulus transduced into a biochemical signal which ultimately elicits a response (curvature) in a plant? Simply put, how does a plant 'know' which way is down?
