Research Area

Gravity is an ever-present environmental factor that regulates the growth direction and architecture of individual plants. From the evolutionary perspective, acquiring the capability to sense and respond to gravity dramatically expanded the living space of plants. How plants perceive and respond to gravity is a fundamental question in biology, which has attracted scientific investigation for centuries. However, the core mechanism of gravity perception is still a mystery. My lab uses Physcomitrella, Arabidopsis and Rice as models to investigate gravity perception and signal transduction. We are particularly interested in: (1) The molecular mechanism of gravity perception; (2) The molecular mechanism of the determination of gravitropic orientation. These studies will benefit the improvement of crop traits on earth and even crop breeding in space with microgravity environment.
