A membrane-bound group of starch grains ( seeamyloplast) that according to the starch statolith hypothesis acts as a sensor to gravity. Starch statoliths are found in specialized cells (statocytes) in the root cap at the growing tip, and in the tissues close to the vascular bundles in shoots.

WebOur results indicate that auxin-mediated statolith production relies on the TIR1/AFB-AXR3-mediated auxin signaling pathway. In summary, we propose a dual role for auxin in gravitropism: the regulation of both gravity perception and response.
