What happens to plant growth when you remove gravity?

It is well known that plant growth patterns are influenced by a variety of stimuli, gravity being one amongst many. On Earth plant roots exhibit characteristic behaviors called 'waving' and 'skewing', which were thought to be gravity-dependent events. However, Arabidopsis plants grown on the International Space Station (ISS) have demonstrated this theory wrong, according to a new study: root ‘waving’ and ‘skewing’ occur in spaceflight plants independently of gravity.
