Thigmomorphogenesis

Thigmomorphogenesis (Thigma --> to touch in Greek) is the response by plants to mechanical sensation (touch) by altering their growth patterns. In the wild, these patterns can be evinced by wind, raindrops, and rubbing by passing animals.

Botanists have long known that plants grown in a greenhouse tend to be taller and more spindly than plants grown outside. M.J. Jaffe discovered in the 1970s that regular rubbing or bending of stems inhibits their elongation and stimulates their radial expansion, resulting in shorter, stockier plants.
