In the Asia regions, the most important staple food consumed by nearly one-half of the world’s population is the rice. However, important diseases of rice namely blast, brown spot, sheath blight and grain discoloration are major limitations on rice production and are becoming more severe on rice grown in silicon (Si) depleted soils, with blast being the most devastating disease. fi00175This review presents the research findings on the role of Si in plant protection against diseases, focusing on rice. Absorption of Si in plants takes place in the form of monosilicic acid and rice is known for its capability to actively absorb Si in high amounts. The possible mechanisms of Si mediated alleviation of disease infection are also being explored in this paper.
