Outline of Final Research Achievements

It is needed to understand a role of the heavy metal-sensitivity of normal plants to establish the technologies of heavy metal decontamination by hyperaccumulators. We analyzed a His-type metal binding peptide (dehydrin) which is commonly found in plants. Although the peptide shows the intrinsically disordered state under the normal condition, it forms aggregates with generating reactive oxygen species which can damage cells at the high concentration of heavy metals. Such characteristics of the peptide are similar to those of amyloids in brain diseases. This peptide can control the sensitivity to heavy metals in plants.
