Rice ( Oryza sativa L.) is a typical silicon (Si)-accumulating plant, but the mechanism responsible for the translocation from the root to the shoot is poorly understood. In this study, the form of Si in xylem sap was identified by 29 Si-nuclear magnetic resonance (NMR) spectroscopy. In rice (cv....
Cells of Chlamydomonas reinhardtii differentiate into gametes under conditions of nitrogen (N) starvation, expressing the genes for the N-adaptation program and the gamete program. To investigate the regulatory networks of transcription among the N-starvation-inducible genes, we examined the gene...
