Plant Nutrition


In this laboratory, wide aspect of activities on both pure research and technological development has been carried out. Both experimental plants, such as Arabidopsis and cultured tobacco cells as well as crops including rice and soybeans are used for the studies. The research topics include: Protein modification, localization and protein degradation in plant cells: Regulation of organelle dynamics during plant cell growth and differentiation: Physiological, molecular biological and biochemical aspecs of sulfur, phosphate and nitrogen nutrition: Symbiotic nitrogen fixation in legumes: Rational fertilizer use.

Research Theme

  1. Nutritional control of protein localization and protein degradation in plant cells (Autophagy, endocytosis)
  2. Regulation of cellular and organelle dynamics (Cytokinesis, nutritional regulation of cell cycle, exocytosis)
  3. Production of useful compounds in crops using transgenic approach (Recombinantprotein production, regulation of protein glycosylation)
  4. Symbiotic nitrogen fixation in legumes (nodulation, Rj-gene)
  5. Rational fertilizer use (Efficiency, nitrogen loss, pollution, resource recycling)
  6. Physiological and biochemical aspects of mineral and nitrogen nutrition (Mineral absorption, nitrogen metabolism, carbon skeleton, abiotic stress, sulfur assimilation and metabolism)
  7. Transcriptional regulation responding to nutrient starvation (Sulfur deficiency, regulatory element, transcriptional network)
