Effects of aluminum on energy metabolism

铝离子是酸性土壤中抑制植物生长的主要因子。研究了铝对植物的毒性和耐受性机制，重点研究了主要培养的烟草细胞系和烟草植株的能量（糖）代谢。我们的研究结果提示了一种新的耐铝机制，该机制将能量代谢从呼吸转移到乳酸发酵，从而避免了铝胁迫下线粒体功能障碍产生活性氧（ROS）。

Aluminum ion is a major factor to inhibit plant growth in acidic soils. Mechanisms of aluminum toxicity and tolerance in plants were examined, focusing on energy(sugar) metabolism in mainly cultured tobacco cell lines and tobacco plant. Our results suggest a novel aluminum tolerant mechanism which shifts energy metabolism from respiration to lactate fermentation so that the production of reactive oxygen species(ROS) via dysfunction of mitochondria under aluminum stress could be avoided.
