中文摘要：

铝胁迫是酸性土壤上影响作物产量最重要的因素之一．目前，全球土壤酸化程度进一步加剧了铝胁迫．植物可通过将铝离子与有机酸螯合储藏于液泡和从根系中排出铝毒．排出铝毒主要通过苹果酸转运蛋白ALMT和柠檬酸转运蛋白MATE的跨膜运输来实现．编码ABC转运蛋白和锌指转录因子的基因与植物抗铝胁迫有关．这些抗铝毒基因的鉴别使得通过转基因和分子标记辅助育种等生物技术来提高农作物的抗铝毒能力成为可能。最后提出了植物抗铝胁迫研究中需要解决的关键问题及今后的研究方向．

英文摘要：

Aluminum （A1） stress is one of the most important factors affecting the plant growth on acid soil. Currently, global soil acidification further intensifies the A1 stress. Plants can detoxify A1 via the chelation of ionic A1 and organic acids to store the ionic A1 in vacuoles and extrude it from roots. The A1 extrusion is mainly performed by the membrane-localized anion channel proteins A13~- activated malate transporter （ALMT） and multi-drug and toxin extrusion （MATE）. The genes en- coding ABC transporter and zinc-finger protein conferred plant A1 tolerance have also been found. The identification of these Al-resistant genes makes it possible to increase the A1 resistance of crop plants and enhance their production by the biological methods such as gene transformation and mark-associated breeding. The key problems needed to be solved and the possible directions in the researches of plant A1 stress resistance were proposed.
