- More recently, however, the Arabidopsis root movements were reinterpreted as the combined effect of essentially three processes, circumnuation, gravitropism and negative thigmotropism.
- Negative thigmotropism is movement away from an object, such as a root away from a rock in the soil.
- One of the most common examples of thigmotropism is seen in tendrils, which wrap around any object with which they come in contact.
- Example sentences
- In the absence of this force, the root pattern will depend only on the circumnutating movement, since the negative thigmotropic reaction, dependent on gravitropism, will also be excluded.
- Clematis petioles are positively thigmotropic and its fun to make your own observations of this phenomenon.
- Later experiments proved that the thigmotropic response is possibly the strongest tropic response in plants.
