Over 40% of arable land in the world is acidic. Al stress has become a global agricultural problem affecting plant growth and limiting crop production in acidic soils. Plants have evolved different regulatory mechanisms of adaptation to exogenous environmental challenges, such as Al stress, by altering their growth patterns. In the past decades, several key genes involved in plant response to Al stress and the mechanism of Al detoxification have been revealed. However, the signaling pathways of plant response to Al stress and the regulatory mechanism of plant Al tolerance remain poorly understood. In this review, we summarized the findings of recent studies on the plant Al tolerance mechanism and the molecular regulation mechanism of phytohormones in response to Al stress. This review improves our understanding of the regulatory mechanisms of plants in response to Al stress and provides a reference for the breeding of Al-tolerant crops.
世界上超过 40%的可耕地呈酸性。铝胁迫已成为全球性农业问题，影响植物生长并限制酸性土壤中作物的产量。植物通过改变其生长模式，进化出了不同的适应外源环境挑战的调节机制，如铝胁迫。在过去的几十年中，已经揭示了几种参与植物对铝胁迫反应的关键基因和铝解毒的机制。然而，植物对铝胁迫的信号通路以及植物耐铝性的调节机制仍知之甚少。在这篇综述中，我们总结了最近关于植物耐铝性机制和植物激素对铝胁迫响应的分子调节机制的研究结果。这篇综述增进了我们对植物应对铝胁迫的调节机制的理解，并为耐铝作物的培育提供了参考。
