| Abstract: | Acid soils extensively exist on the globe and aluminum toxicity is one of the main factors limiting crop growth therein. A review was presented to address aluminum toxicity to plants and mechanism of aluminum tolerance of plants, and summarized advancements in the study on biological means mitigating aluminum toxicity to plants in acid soils, such as genetic rebuilding of plants tolerance to aluminum toxicity, and inoculating of exotrophic mycorrhizal fungi or other aluminum-tolerant microorganisms into the soil or plants. The above-mentioned biological means will have bright prospects in application to remedying eco-environment of acid soils. |
