Research Abstract

Molecular mechanisms of homeostasis of low molecular weight substances were studied in plant cells and tissues. We have focused on the phosphate homeostasis using Arabidopsis plants and cells, or Poplar tree. First we clarified a relationship between root architecture and environmental phosphate status. We found cooperative roles of phosphate and iron are quite important. Second, we analyzed the re-translocation system of phosphate from older leaves to younger leaves of Arabidopsis based on the gene expression. Further, we observed phosphate recovery of poplar leaves during late summer and autumn. Last, we analyzed cell and tissue metabolism of inositol phosphates during seed development.
