| Research Abstract |
Among 17 investigated metal elements, zinc accumulation was drastically different between two Lotus japonicus cultivars Gifu and Miyakojima. By comparing Zn-65 distribution images, zinc uptake and translocation activities were higher in Gifu. The zinc accumulation in shoot was investigated with about 80 RILs and several major QTLs were found. The genes located on these QTL were investigated based on the L. japonicus genome sequence and several genes annotated zinc transporter, which gene expression levels were higher in Gifu, were identified.
