The invention discloses a rice OsCASP1 gene; the sequence of the gene is shown as SEQ ID NO.1; the encoded protein of the rice OsCASP1 gene contains four transmembrane structural domains; and the sequence of the encoded protein is shown as SEQ ID NO.2. In the technical scheme of the invention, an OsCASP1 over-expressed transgenic strain is constructed; and the fact that the over-expressed strain enhances the calcium tolerance under a high-calcium condition is found. OsCASP1 over-expression can induce early-stage formation of a root tip casparian band; accumulation of calcium in stems is selectively reduced; and therefore the adaptability of rice to the high-calcium environment is improved. According to the invention, the understanding of the relationship among the formation of the casparian band, calcium absorption and calcium tolerance in rice is enhanced; and a method for obtaining a high-calcium-tolerance material is provided for preventing and treating heavy metals. 本发明公开了一种水稻OsCASP1基因，所述基因的序列如SEQ ID NO.1
