Investigations carried out on maize roots under microgravity and hypergravity revealed that
gravity conditions have strong effects on the network of plant electrical activity. Both the
duration of action potentials (APs) and their propagation velocities were significantly affected
by gravity. Similarly to what was reported for animals, increased gravity forces speed-up APs
and enhance synchronized electrical events also in plants. The root apex transition zone
emerges as the most active, as well as the most sensitive, root region in this respect.
