- Thigmotropism abstract "It is a directional growth movement of curvature which occurs in response to stimulus of contact. Thigmatotropism is found in twiners and tendrils. After initial contact with support due to nutation, the tendril or twiner shows less growth in the region of contact and more growth on the other side. As a result they bend over the support. Later on bending or coiling may occur in lower parts of the tendril as well. Thigmotropism is a movement in which a plant moves or grows in response to touch or contact stimuli. The prefix thigmo- comes from the Greek for "touch" (θιγμός). Usually thigmotropism occurs when plants grow around a surface, such as a wall, pot, or trellis. Climbing plants, such as vines, develop tendrils that coil around supporting objects. Touched cells produce auxin and transport it to untouched cells. Some untouched cells will then elongate faster so cell growth bends around the object. Some seedlings also exhibit triple response, caused by pulses of ethylene which cause the stem to thicken (grow slower and stronger) and curve to start growing horizontally.Roots also rely on touch to navigate their way through the soil. Generally, roots have a negative touch response, meaning when they feel an object, they would grow away from the object. This allows the roots to go through the soil with minimum resistance. Because of this behavior, roots are said to be negatively thigmotropic. Thigmotropism seems to be able to override the strong gravitropic response of even primary roots. Charles Darwin performed experiments where he found that in a vertical bean root, a contact stimulus could divert the root away from the vertical.Other kinds of tropisms include gravitropism, phototropism, hydrotropism, and heliotropism. Gravitropism is the principle of turning based on gravity. Phototropism is the principle of turning based on the source of the plant's light. Hydrotropism is when the plant's roots grows toward a source of water. Heliotropism is when a plant follows the sun throughout the day. The helianthus (sunflower) is a plant that uses heliotropism.".
