Thigmomorphogenesis

Definition

Thigmomorphogenesis is the process by which plants change their growth patterns in response to mechanical stimulation such as touch, wind, or rain. It involves alterations in plant structure and physiology that enhance their ability to withstand physical stress.

5 Must Know Facts For Your Next Test

1. Thigmomorphogenesis can result in shorter, thicker stems and increased root growth.
2. The process helps plants become more resistant to environmental stresses like strong winds.
3. Mechanoreceptors in plant cells detect mechanical stimuli and trigger signaling pathways for growth changes.
4. Thigmomorphogenesis involves hormonal changes, including increased ethylene production.
5. This phenomenon is observed in both natural environments and agricultural settings where plants may be mechanically stimulated by farming practices.
