摘　要：摘　要：铝毒是作物在酸性土壤中生长的主要限制因素，水稻作为耐铝毒较强的作物，有着精细的抗铝机制。水稻的高抗铝性受多基因控制，其中包括抗铝转录因子基因、多药及毒性化合物外排家族(multidrug and toxic compound extrusion， MATE)基因、铝特异转运蛋白基因、液泡ATP结合盒(ATP binding cassette， ABC)转运蛋白基因、细菌型ABC转运蛋白基因、镁转运蛋白基因等。主要围绕以上基因概述水稻抗铝机制的最新研究进展和对未来的研究进行展望。

Abstract: Abstract: Aluminum (Al) toxicity is the major factor limiting crop productivity on acidic soils. Rice (Oryza sativa L.) is one of the most Al-resistant crops， and has complicated mechanisms for Al tolerance. Many Al-resistant genes in rice have been cloned， including Al resistance transcription factor 1 (ART1)， multidrug and toxic compound extrusion (MATE) gene， nramp aluminum transporter 1 gene， tonoplast-localized half-size ABC transporter gene， bacterial-type ABC transporter gene， magnesium transporter gene， etc. We reviewed the recent studies on the Al-resistant mechanisms and predicted the future directions in this field.
