Related to Statoliths: statocyst, thigmotropism


1. One of the small movable calcareous particles in a statocyst.
2. One of the starch grains or other solid particles in a plant cell thought to function in the plant's response to gravity.


1. (Zoology) Also called: otolith any of the granules of calcium carbonate occurring in a statocyst: movement of statoliths, caused by a change in position of the animal, stimulates hair cells, which convey the information to the brain by nerve fibres
2. (Botany) any of various movable inclusions, such as starch grains, that occur in plant cells and are thought to function in geotropic responses
ˌstatoˈlithic adj


(ˈstæt l ɪθ)

any of the granules of lime, sand, etc., contained within a statocyst.

Otoliths are calcareous structures that act as statoliths in the internal ear of fish (Su, 2005) and are well known for their time-recording structure that is widely used in studies to assess age (Lowerre-Barbieri et al.

The jellies have genes for the calcium carbonate needed to make sensory structures called statoliths, as well as other genes for collagen.
When auxins are present in the root, they act hand in hand with columel statoliths (which are sensitive to gravity), leading to positive geotropic growth (ALONI et al.
When the plant is placed in the horizontal position, statoliths fall to the bottom of the cell, which causes changes in IAA gradients resulting in differential growth.
At 4[degrees]c, starch-containing statoliths sedimented normally in wildtype but auxin transport was abolished indicating that the mutants are affected in an aspect of signal transduction that occurs after statolith sedimentation but prior to auxin transport.
