In space with no gravity, which way do plant roots grow?

Okay I remember from high school that if you plant a seed in dirt, the seed automatically knows which way to direct its roots due to gravity. But imagine a scenario similar to the movie Walle where we are traveling through space in the middle of the galaxy without any local planets or stars influencing our ship. If we stuck a seed into a dirt container in our ship, would the roots branch out randomly, or point towards the nearest system? 

Another question if we were in one of those spinning cylindrical colonies (similar to the ones in gundam) in space that simulates gravity. Gravity is the attraction of mass, but could the seed tell that this centripetal force isn’t really gravity? Or would it be tricked to thinking it is gravity and still plant it’s roots outward of this spinning colony.

Follow up extremely hypothetical question assuming the seed roots do grow normally in a spinning colony: if we planted a seed here on earth, but made a small device that spun the dirt and seed in a circle (similar to the colony in space), but the force acting on the seed was greater than earths gravity, would the roots point outward in our little device or still down towards gravity?

Long answer short: there is more than just gravity directing the roots. Soil density, water, and nutrient locations all play a factor. Likely, with the right soil and light source, plants will grow with relative normalcy in no, low, or simulated gravity.
