| Outline of Final Research Achievements |
A major inhibitory factor of crop production in acidic soils is aluminum (Al) ion. Using cultured tobacco cell lines and seedlings of tobacco, we found (1) a novel avoidance mechanism of ROS production in mitochondria by repression of TCA cycle but enhancement of fermentations in cytosol even under normoxia, which is similar to the Warburg effect reported in cancer cells, (2) an increase in Al tolerance by the over-expression of sucrose transporter in the plasma membrane, and (3) the involvement of vacuolar processing enzyme in cell death mechanism under Al stress.
