Cellulose intrafibrillar mineralization of biological silica in a rice plant

Abstract The essence of morphological design has been a fascinating scientific problem with regard to understanding biological mineralization. Particularly shaped amorphous silicas (plant opals) play an important role in the vital activity in rice plants. Although various organic matters are associa...
