Plant Nutritional Physiology


Plant Nutritional Physiology laboratory is focusing on sustainable crop production and the conservation of agricultural environment by introducing not only applicable field techniques but also molecular-level gene technologies.

1) Improving crop productivity and quality under adverse environmental conditions (Saneoka, H.)

2) Molecular physiology and genetic engineering of abiotic stress tolerance in plants (Ueda, A.)
