低磷（Pi）的有效性和高铝（Al）的毒性构成了两个主要的植物矿质营养胁迫，限制植物生产力在酸性土壤。在模式植物如拟南芥和水稻（Oryza sativa）以及其他植物中，对参与两种胁迫的基因和信号网络的鉴定的进展已经揭示了一些因素如有机酸（OAs）、细胞壁性质、植物激素和铁（Fe）稳态相互关联。此外，OAs参与招募许多植物生长促进细菌，这些细菌能够分泌OAs和磷酸酶，以增加Pi的可用性并降低Al毒性。在这篇综述文章中，我们总结了这些相互作用机制，植物处理铝毒和磷饥饿，重点是OA分泌调节，植物生长促进细菌，转录因子，转运蛋白，激素和细胞壁相关激酶的背景下，根发育和根系结构重塑，在提高磷利用效率和铝抗性酸性土壤中起着决定性作用。
Low phosphate (Pi) availability and high aluminum (Al) toxicity constitute two major plant mineral nutritional stressors that limit plant productivity on acidic soils. Advances toward the identification of genes and signaling networks that are involved in both stresses in model plants such as Arabidopsis thaliana and rice (Oryza sativa), and in other plants as well have revealed that some factors such as organic acids (OAs), cell wall properties, phytohormones, and iron (Fe) homeostasis are interconnected with each other. Moreover, OAs are involved in recruiting of many plant-growth-promoting bacteria that are able to secrete both OAs and phosphatases to increase Pi availability and decrease Al toxicity. In this review paper, we summarize these mutual mechanisms by which plants deal with both Al toxicity and P starvation, with emphasis on OA secretion regulation, plant-growth-promoting bacteria, transcription factors, transporters, hormones, and cell wall-related kinases in the context of root development and root system architecture remodeling that plays a determinant role in improving P use efficiency and Al resistance on acidic soils.
