植物铜耐性机理的研究进展
Research Progress of the Tolerance Mechanism of Plants to Copper
-
摘要: 主要从植物根细胞壁积累固定、细胞膜对铜的吸收控制、金属配体的螯合作用、铜在系统液泡的分隔机制及胁迫蛋白的合成5个方面,分别阐述植物对铜分子的耐性机制的研究进展,全面了解了铜在植物中的亚细胞分布、铜在植物根系到地上部分运输过程的转运机制以及植物在铜胁迫下的抗性反应等。并在此基础上提出了存在的问题以及今后研究的重点。Abstract: Research progress of the tolerance mechanism of plants to copper was reviewed in five aspects:i) the copper accumulation of plant cell wall; ii) the absorption and control of plant membrane; iii) the chelation of metal ligands; iv) the separation of vacuole; and v) the synthesis of Cu-responsive proteins. The review provided us a better understanding of the subcellular distribution of copper in plant, the transport mechanism of copper from root to shoot of plants and the resistance of pants under copper stress. Based on the progress, the prospects of future studies were suggested.
