Outline of Final Research Achievements

Multi-mineral accumulation observed in Lotus japonicus B-129 line, compared to MG-20 line, was investigated based on mineral behavior within the plant and gene expressions in the root tissue. In this research, zinc and cesium were focused on as one of the essential and non-essential element for plant, respectively. Although the integrated mechanism regulating the accumulation of multi-mineral was not clear, the highly controlled mineral transport system in B-129 involved in the adaptation to the nutrition deficiency for essential element was observed. And that suggests the multi-mineral accumulation in B-129 is the results of the difference of the regulation pattern of mineral acquisition and transport.
