A Review on the Effects of Cell Wall on the Resistance of Plants to Metal Stress
植物根系细胞壁在提高植物抵抗金属离子毒性中的作用

The mechanisms of the cell walls of plants to resist metal toxicity are reviewed in this paper. Two kinds of mechanisms are involved: One is the compartmenzation of cell walls; the other is the adaptability of cell walls. The resistance of plants to metals is enhanced largely by both mechanisms of cell walls. The possibility of enhancing the resistance of plants to metals by modulating the physical-chemical characteristics of cell walls is also reviewed. The mechanisms of resistance increased to metals by arbuscular mycorrhizal fungi colonization can also be explained by the changes of cell walls.
