Aluminium (Al) toxicity is one of the major abiotic stress problems around the globe where acidic soil is present. Al shows a toxic effect between the soil pH 4.5 and 5.5. Root growth inhibition is the most prodigious symptom of Al toxicity in plants. Aluminium toxicity adversely affects the plant growth and development which ultimately reduces the yield. However, the extent of toxicity depends on the genotype of the plant, that is the plant is either the Al-sensitive or Al-tolerant type. Plants have several mechanisms to cope with the toxic effects of aluminium which include exclusion mechanism and internal tolerance mechanism. This review discusses the harmful impacts of aluminium on morphological, anatomical, physio-biochemical, and molecular aspects of the plant. This review also discusses the strategies to reduce the toxic effects of aluminium in plant and various aluminium-responsive genes which can be used in genetic manipulation for better crop development.

铝（Al）毒性是存在酸性土壤的全球主要非生物胁迫问题之一。Al在土壤pH 4.5至5.5之间显示毒性作用。根生长抑制是植物中铝毒性的最严重症状。铝的毒性会对植物的生长和发育产生不利影响，最终降低产量。但是，毒性程度取决于植物的基因型，即植物是对铝敏感的类型还是对铝耐受的类型。植物有多种机制来应对铝的毒性作用，包括排斥机制和内在耐受机制。这篇综述讨论了铝对植物形态，解剖，生理生化和分子方面的有害影响。
