| Outline of Final Research Achievements |
Nodes of graminaceous plants containing highly developed and fully organized vascular systems, which involved in “inter-vascular transfer” of mineral nutrients. In this study, we identified novel node localized mineral transporters for phosphorus, boron and iron in rice. Each transporter mediate inter-vascular transfer and contribute to preferential distribution control of each elements. In addition, we conducted promoter analysis of rice silicic acid channel Lsi6, which highly express in xylem transfer cells in enlarged vascular bundles in node. We estimate a regulatory promoter region for the tissue specific gene expression.
