铝(Al)毒胁迫会引起植物一系列的生理生化响应。本文针对 Al 毒胁迫下植物的不同响应机制展开了综述,分别介绍了根系有机酸的分泌、根表黏胶物质、细胞壁成分的变化及 pH 和酚类物质的变化与抗 Al 性的关系,尤其以细胞壁胼胝质的形成为重点给予了详细的论述。最后结合 Al 毒的研究现状,为未来相关领域的研究提出了自己的一些看法。
Abstract:
Al stresses could induce a series of physiological and biochemical changes in plants. In this paper, different response mechanisms of plants against Al stresses were reviewed. These responses, including exudation of organic acids by roots, formation of mucilage on root surfaces, component changes of cell wall, changes of pH and phenolic constituent, were introduced respectively. The component changes of cell wall under Al stresses were described particularly in detail. Finally, some suggestions on further study of Al toxicity were put forward based on the current research.
