Schematic representation of advanced plant structures. Graviperception takes place in specialized gravity-sensing cells (statocytes) in the root cap. These statocyte cells are most probably present in the endodermal region of the plant cells, where starch granule amyloplast sedimentation occurs under stimulated gravity conditions. A The PIN-formed protein also contributes to the facilitation of auxin efflux and influx under stimulated gravity conditions, and B shows that different parts of the plants perceive gravistimulation, adopted from Kolesnikov et al [25]. whereas C shows the amyloplast position in the roots and shoot part of the plant. It also describes the amyloplast sedimentation in normal gravity, microgravity, and simulated microgravity conditions
