thigmotropism

This is an example of thigmotropism, or acting in response to a touch stimulus.

When insects are first trapped, the leaves roll lengthwise by thigmotropism toward the center.

Usually thigmotropism occurs when plants grow around a surface, such as a wall, pot, or trellis.

Interestingly, thigmotropism seems to be able to override the strong gravitropic response of even primary roots.

It is an example for Thigmotropism.

Thigmonasty differs from thigmotropism in that it is independent of the direction of the stimulus.

Some species can bend their leaf edges slightly by thigmotropism, bringing additional glands into contact with the trapped insect.

Once attached, the spore germinates by growing a germ tube and eventually locates a stoma by a touch responsive process known as thigmotropism.

The time scale of thigmonastic responses tends to be faster than thigmotropism because thigmonasty depends on turgor and bistable mechanisms rather than growth or cell division.

It is implicated in regulating such diverse and fundamental cellular process as cytoplasmic streaming, thigmotropism, gravitropism, cell division, cell elongation, cell differentiation, cell polarity, photomorphogenesis and plant defense and stress responses [ 1, 3, 4].

The sundew genus (Drosera) consists of over 100 species of active flypapers whose mucilage glands are borne at the end of long tentacles, which frequently grow fast enough in response to prey (thigmotropism) to aid the trapping process.

Further stimulation of the lobe's internal surfaces by the struggling insects causes the lobes to close even tighter (thigmotropism), sealing the lobes hermetically and forming a stomach in which digestion occurs over a period of one to two weeks.
