| Outline of Final Research Achievements |
Application of glutathione to leaves activated Zn absorption in roots, Zn transport and Zn accumulation in shoots in oilseed rape plants. These activations are induced by some signals that are transported via sieve tubes. The ratio of glutathione, reduced form, to glutathione, oxidized form, has changed by application of glutathione to leaves site-specifically. Abundance of several proteins in sieve tubes also has changed by glutathione treatment. These substances in sieve tubes were expected to be signals. Positron imaging experiments enabled us to visualize Zn movements in oilseed rape plants treated with glutathione.
