Aluminum (Al) is a major growth-limiting factor for plants in acid soils. The primary site of Al accumulation and toxicity is the root meristem, and the inhibition of root elongation is the most sensitive response to Al. Al cannot catalyze redox reactions but triggers lipid peroxidation and reactive oxygen species (ROS) production in roots. Furthermore, Al causes respiration inhibition and ATP depletion. Comparative studies of Al toxicity in roots with that in cultured plant cells suggest that Al causes dysfunction and ROS production in mitochondria, and that ROS production, but not lipid peroxidation, seems to be a determining factor of root-elongation inhibition by Al.
