| Abstract: |
| Abiotic stress has an effect on the normal growth of plants, and the plant cell wall is the first barrier to resist external stress. Pectin, hemicellulose, protease and other components of cell wall participate in the physiological response to stress. The pectin can combine with the metal ions through the negatively charged carboxyl group, and increase the metal ion binding ability to reduce the transhipment of metal ions to cell wall by reducing the level of pectin methyl. Hemicellulose can also combine with metal ions, including wood glucan in combine with metal ions play an important role. The cell wall also participates in the physiological response to plant salt stress. The expression of the cell wall extension protein gene regulates the plant’ s salt tolerance, and the changes in the cell wall are also perceived by the plant and regulate the plant’ s salt tolerance. In this paper, recent studies on the roles of cell wall polysaccharides and cell wall proteins in the tolerance of
harmful metals and salt in plants were reviewed in order to have a comprehensive understanding of the role of plant cell wall in resistance to abiotic stress. |
