    Abstract
  • In this review, the biological effects of gravity change on plant cells based on the data obtained from both ground-based research and space experiment on board the Chinese spaceship Shenzhou-8 are discussed. These data demonstrate the impact of direction and intensity changes of gravity on cell wall metabolism during plant gravitropism and cells in the state of weightlessness. The maintaining of cell shape requires the balance between cell wall rigid and cell turgor pressure is assumed. When the turgor pressure is greater than the rigid, the balance is broken which may lead to increased cell volume. Therefore the change of gravity may affect the growth of cells through the influence of the balance between cell wall rigidity and cell turgor pressure.
