Abstract:

Aluminum toxicity in acid soils is one of the main factors limiting agricultural production and yields. Plants respond differently to aluminum toxicity. External exclusion and internal detoxification are the mains mechanisms for plants to resist aluminum toxicity. This review is including aluminum toxicity to plants,the role of exogenously added regulatory factors in plants to alleviate aluminum toxicity,the function and transcriptional regulation of aluminum-tolerant genes,and the impact of microbial communities on plants under aluminum ion stress. As well as the future research direction is prospected,aiming that this paper will provide a basis for related research in the future.

Key words: aluminum toxicity, aluminum-tolerant mechanism, aluminum-tolerant gene, aluminum-tolerant bacteria
