缓解植物铝毒害的相关基因调控研究进展

Research progress in the regulation of genes involved in alleviating plant aluminum toxicity

铝是导致土壤酸化、阻碍植物生长的重要因素之一。铝对植物从生长到生理生化过程,从细胞水平到基因水平均有不同程度的负面影响。如何提高植物耐铝能力、缓解铝对植物的毒害,是多年来人们关注的问题。本文从有机酸、活性氧代谢、植物激素、矿质营养元素等方面,对缓解植物铝毒害的相关基因调控的研究进展进行了综述。研究表明,有机酸在缓解植物铝毒害中具有至关重要的作用,这是迄今人们在该领域取得的最重要的进展,本文对此方面的相关研究成果做了重点介绍。提出未来应继续重视有机酸缓解铝毒害的研究,加强与缓解林木铝毒害密切相关的基因、转录因子及其机制方面的研究。

Aluminum is one of the most important factors that lead to soil acidification and inhibition of plant growth.It has negative effects with different magnitudes on plant growth,physiological and biochemical process,as well as processes at cell level and gene level.How to improve the aluminum tolerance of plants and alleviate the toxicity to plants has been a concern for many years.Here,we gave a review on the research progress of gene regulation related to alleviating aluminum toxicity in plants from the aspects of organic acids,active oxygen metabolism,plant hormones,and mineral nutrients.It is well known that organic acids play an important role in mitigating aluminum toxicity in plants.This is the most important progress in this field,which were mainly introduced in this review.We suggested that more attention should be paid to the research of organic acids in alleviating aluminum toxicity,and that the research on genes,transcription factors and their mechanisms closely related to alleviating aluminum toxicity in trees should be strengthened.
