| Research Abstract |
Phytate is the storage form of phosphorus in plants. Our aim of this study was to create the phytate-accumulator rice and the low-phytate rice grains by controlling biosynthesis of phytate through genetically modified technology. The phytate-accumulator rice plant can be used for the phosphorus collection from the lakes and marshes that was polluted by excessive phosphorus. The low-phytate rice grains can be used as fodder with a high nutritive value with a good digestive absorption, and they reduce the impact of animal manures on the pollution load of water bodies. In this study, the low-phytate rice at the practical use level was achieved, and the strategy for the production of phytate-accumulator rice became clear.
