植物应答铝毒的分子机制研究进展

Research Progress on the Molecular Mechanism of Plants Response to Aluminum Toxicity

酸性土壤中的铝毒是限制农业生产和作物产量的主要因子之一,不同植物对铝毒响应不同。外部排斥机制和内部耐受机制是植物抗铝毒的最主要的两种生理机制。综述了铝毒对植物的危害;外源添加调节因子在植物缓解铝毒中的作用;耐铝基因的功能和转录调控;以及微生物群落在铝离子胁迫下对植物的影响;展望了未来的研究方向,并希望为之后相关研究提供依据。

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.
