Research Abstract

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.
